Аннотация: Soil and water protection functions of boreal forests in West Sayan and Northern Priangarye are greatly effected by forest industry, firstly, timber cutting. After concentrated timber felling all ecological forest functions are changing. On the base of long time forest and hydrology investigations on cuts and in secondary forest an estimation of water balance was made taking into account forest structure change during regeneration succsssion. Obtained data showed soil erosion rate depending on soil properties, topography, and moisture conditions, the latter determining surface runoff development.

Аннотация: The relative role of fire and of climate in determining canopy species composition and aboveground carbon stocks were investigated. Measurements were made along a transect extending from the dark taiga zone of central Siberia, where Picea and Abies dominate the canopy, into the Larix zone of eastern Siberia. We test the hypotheses that the change in canopy species composition is based (1) on climate-driven performance only, (2) on fire only, or (3) on fire-performance interactions. We show that the evergreen conifers Picea obovata and Abies sibirica are the natural late-successional species both in central and eastern Siberia, provided there has been no fire for an extended period of time. There are no changes in performance of the observed species along the transect. Fire appears to be the main factor explaining the dominance of Larix and of soil carbon. Of lesser influence were longitude as a proxy for climate, local hydrology and active-layer thickness. We can only partially explain fire return frequency, which is not only related to climate and land cover, but also to human behavior. Stand-replacing fires decreased from 300 to 50 yrs between the Yenisei Ridge and the upper Tunguska. Repeated non-stand-replacing surface fires eliminated the regeneration of Abies and Picea. With every 100 yrs since the last fire, the percentage of Larix decreased by 20%. Biomass of stems of single trees did not show signs of age-related decline. Relative diameter increment was 0.41 +/- 0.20% at breast height and stem volume increased linearly over time with a rate of about 0.36 t C ha(-1) yr(-1) independent of age class and species. Stand biomass reached about 130 t C ha(-1)(equivalent to about 520 m(3) ha(-1)). Individual trees of Larix were older than 600 yrs. The maximum age and biomass seemed to be limited by fungal rot of heart wood. 60% of old Larix and Picea and 30% of Pinus sibirica trees were affected by stem rot. Implications for the future role of fire and of plant diseases are discussed.

Аннотация: Siberian Rivers account for a great part of water discharge into the Arctic Ocean. Along with the regional climate and the presence permafrost, hydrological processes occurring in catchments of the boreal taiga rivers are controlled by forest harvesting levels. Forests of the Lower Angara region have been harvested extensively over the past fifty years. As a result, forest area has been reduced and forest age structure and composition have changed. These changes are reflected in the natural water budget structure and hydrological regimes of areas. The study revealed that hydrological effects of forest logging conducted in Siberia characterized by a highly continental climate and, hence, severe forest growing conditions differ from those observed for the European Russia.

Аннотация: The time series of various parameters of satellite imagery (NDVI/EVI, temperature) during the growing season were considered in this work. This means that satellite images were considered not like a number of single scenes but like temporal sequences. Using time series enables estimating the integral phenological properties of vegetation. The basis of the developed technique is to use one of the methods of transformation of the multidimensional space in order to get the principal components. The technique is based on considering each dimension of the multidimensional space as satellite imagery for a specific date range. The technique automatically identifies spatial patterns of vegetation that are similar by phenology and growing conditions. Subsequent analysis allowed identification of the belonging of derived classes. Thus, the technique of revealing the spatial distribution of different dynamical vegetation patterns based on the phenological characteristics has been developed. The technique is based on a transformation of the multidimensional space of states of vegetation. Based on the developed technique, areas were obtained with similar interannual trends. В© 2011 SPIE.

Аннотация: River flow is vitally important to many human activities. River flow is influenced by climatic and land-cover changes. Land-use practices have a significant effect on water flow and quality. Land use can change surface runoff, which in turn can be used as an environmental indicator of a land use level of sustamability. Along with the regional climate, hydrological processes occurring in river basins in Siberia and mountainous Kyrgyzia are controlled by forest logging and afforestation. The method used to analyse annual river flow genesis to date allowed the onset of, and assessment of, the level of human activities in the watersheds. Moreover, river flow genesis can be used in land use decision-making. River flow reflects all watershed changes, which can have opposite effects, thus compensating for each other. This study confirmed that river flow changes in time, thus reflecting land cover changes in watersheds. Copyright В© 2009 IAHS Press.

Аннотация: Forest areas can intercept surface runoff from upslope bare areas and transfer it to interflow. Therefore, planting protective forests along the banks of rivers, reservoirs, and lakes preserves natural water sources from pollution. Depending on the particular landscape conditions, the streamside forest shelterbelt (SFS) width is often either wider or narrower than the ecologically substantiated width. As a result, either water quality worsens or the ecologically unjustified prohibition of forest use leads to economic losses. The assessment of SFS width using GIS technologies allows considerable simplification of evaluation procedures and their application in practice. DEM processing is integrated into most modern GIS software packages. For example, the popular ESRI ArcGIS package with its Spatial Analyst module provides extra options for calculating a series of relief-based hydrological features, which include calculation procedures for surface flow direction, length of flow-producing slopes and surface flow accumulations. Two algorithms for GIS-based SFS construction were tested for several rivers of the Yenisei basin and Krasnoyarsk Reservoir, Siberia. The first algorithm is technically simple and based on empirical equations of runoff slope length, slope steepness and soil infiltration. The second one includes a three-dimensional flow accumulation procedure and thus it is more sensitive to real surface structure. Both algorithms are ready to be used in practice. The results obtained indicate that, on average, the SFS width along banks of large rivers might be reduced, while in some cases it should be widened along the banks of small streams.

Аннотация: With reference to 2001-2005, the fluxes of dissolved organic matter (DOM) are analyzed in a water stream of the northern taiga subzone of continuous permafrost. Dynamics of hydroclimatic parameters is shown during a frost-free period. It is found that, in spite of a potential decrease in the DOM concentrations with the increased thickness of a seasonally thawed layer, one observes their direct dependence on the precipitation amount and part that enters the water stream. Seasonal variations in the DOM qualitative composition are determined. The basic DOM part exported from the watershed is observed during the regimes of a maximum water content (spring flooding and floods). В© Allerton Press, Inc. 2007.

Аннотация: Monitoring the dynamics of the tundra-taiga boundary is critical for our understanding of the causes and consequences of the changes in this area. Because of its inaccessibility, remote sensing data will play an important role. In this study we examined the use of several remote sensing techniques for identifying the existing tundra- taiga ecotone. These include Landsat, MISR and RADARSAT data. High-resolution IKONOS images were used for local ground truth. It was found that on Landsat ETM+ summer images, reflectance from tundra and taiga at band 4 (NIR) is similar, but different at other bands such as red, and MIR bands. When the incidence angle is small, C-band HH-pol backscattering coefficients from both tundra and taiga are relatively high. The backscattering from tundra targets decreases faster than taiga targets when the incidence angle increases, because the tundra targets look smoother than taiga. Because of the shading effect of the vegetation, the MISR data, both multi-spectral data at nadir looking and multi-angle data at red and NIR bands, clearly show the transition zone.

Аннотация: Northern Eurasian ecosystems play an important role in the global climate system. Northern Eurasia (NE) has experienced dramatic climate changes during the last half of the 20th century and to present. To date, how evapotranspiration (ET) and water availability (P-ET, P: precipitation) had changed in response to the climatic change in this region has not been well evaluated. This study uses an improved version of the Terrestrial Ecosystem Model (TEM) that explicitly considers ET from uplands, wetlands, water bodies and snow cover to examine temporal and spatial variations in ET, water availability and river discharge in NE for the period 1948-2009. The average ET over NE increased during the study period at a rate of 0.13 mm year(-1) year(-1). Over this time, water availability augmented in the western part of the region, but decreased in the eastern part. The consideration of snow sublimation substantially improved the ET estimates and highlighted the importance of snow in the hydrometeorology of NE. We also find that the modified TEM estimates of water availability in NE watersheds are in good agreement with corresponding measurements of historical river discharge before 1970. However, a systematic underestimation of river discharge occurs after 1970 indicates that other water sources or dynamics not considered by the model (e.g., melting glaciers, permafrost thawing and fires) may also be important for the hydrology of the region.

Аннотация: Stable Zn isotopes fractionation was studied in main biogeochemical compartments of a pristine larch forest of Central Siberia developed over continuous permafrost basalt rocks. Two north-and south-oriented watershed slopes having distinctly different vegetation biomass and active layer depth were used as natural proxy for predicting possible future climate changes occurring in this region. In addition, peat bog zone exhibiting totally different vegetation, hydrology and soil temperature regime has been studied. The isotopic composition of soil profile from Central Siberia is rather constant with a delta Zn-66 value around 0.2 parts per thousand close to the value of various basalts. Zn isotopic composition in mosses (Sphagnum fuscum and Pleurozium schreberi) exhibits differences between surface layers presenting values from 0.14 to 0.2 parts per thousand and bottom layers presenting significantly higher values (0.5 - 0.7 parts per thousand) than the underlain mineral surface. The humification of both dead moss and larch needles leads to retain the fraction where Zn bound most strongly thus releasing the lighter isotopes in solution and preserving the heavy isotopes in the humification products, in general accord with previous experimental and modeling works [GCA 75:7632-7643, 2011]. The larch (Larix gmelinii) from North and South-facing slopes is enriched in heavy isotopes compared to soil reservoir while larch from Sphagnum peatbog is enriched in light isotopes. This difference may result from stronger complexation of Zn by organic ligands and humification products in the peat bog compared to mineral surfaces in North- and South-facing slope. During the course of the growing period, Zn followed the behavior of macronutrients with a decrease of concentration from June to September. During this period, an enrichment of larch needles by heavier Zn isotopes is observed in the various habitats. We suggest that the increase of the depth of rooting zone, and the decrease of DOC and Zn concentration in soil solution from the root uptake zone with progressively thawing soil could provoke heavy isotopes to become more available for the larch roots at the end of the vegetative season compared to the beginning of the season, because the decrease of DOC will facilitate the uptake of heavy isotope as it will be less retained in strong organic complexes.

Аннотация: Fire can transform the boreal forest landscape, thereby leading to potential changes in the loading of organic matter and nutrients to receiving streams and in the retention or transformation of these inputs within the drainage network. We used the Tracer Additions for Spiraling Curve Characterization (TASCC) method to conduct 17 nutrient-addition experiments (9 single additions of NO3- and 8 combined additions of NH4+ and PO43-) in 5 boreal headwater streams underlain by continuous permafrost and draining watersheds with a range of burn histories (4->100 y since last burn) in the Nizhnyaya Tunguska River watershed in Central Siberia. Hydrology, ambient nutrient concentration, and the ratio of dissolved organic C (DOC) to nutrients drove rates of nutrient uptake in the streams. Nutrients were taken up with greater efficiency and magnitude under conditions with high flow and reduced diffusive boundary layer (DBL), regardless of watershed burn history. Ambient molar ratio of DOC: PO43- explained some variation in ambient uptake velocity (upsilon(f)) for NH4+ and PO43-. We also observed tight coupling between ambient rates of NH4+ and PO43- uptake across the watershed burn-history gradient. These data suggest that fire-driven changes in stream chemistry may alter N and P retention and subsequent export of materials to downstream receiving waters. Climate change is likely to enhance the frequency and intensity of boreal forest fires and alter the extent of permafrost. Therefore, understanding the interactions among C, N, and P in these Arctic systems has important implications for global biogeochemical cycling.

Аннотация: Stable oxygen isotope ratios (δ18O) in trees from high latitude ecosystems are valuable sources of information for recent and past environmental changes, but the interpretation is hampered by the complex hydrology of forests growing under permafrost conditions, where only a shallow layer of soil thaws in summer. We investigated larch trees (Larix gmelinii) at two sites with contrasting soil conditions in Siberia and determined δ18O of water from different soil depths, roots, twigs, and needles as well as δ18O of soluble carbohydrates regularly over two growing seasons. A comparison of results from the 2 yrs revealed an unexpected 'inverse' climate-isotope relationship, as dry and warm summer conditions resulted in lower soil and root δ18O values. This was due to a stronger uptake of isotopically depleted water pools originating from melted permafrost or previous winter snow. We developed a conceptual framework that considers the dependence of soil water profiles on climatic conditions for explaining δ18O in needle water, needle soluble carbohydrates and stem cellulose. The negative feedback of drought conditions on the source isotope value could explain decreasing tree-ring δ18O trends in a warming climate and is likely relevant in many ecosystems, where a soil isotope gradient with depth is observed. © 2016 New Phytologist Trust.

Аннотация: The interannual variations in the characteristics of the seasonal cycle (annual and seasonal amplitudes, winter emission, dates of annual minimum and maximum, and phase) and in the growth rate of atmospheric carbon dioxide concentration over Central Siberia are analyzed for the period from May 2009 to January 2016. The results are based on the continuous monitoring of CO2 concentration at the Zotino Tall Tower Observatory (ZOTTO, www.zottoproject.org). It is found that the seasonal amplitude of CO2 concentration in the atmo spheric surface layer over Western Siberia is 26.4 ± 0.8 ?mol/mol (no long-term trend toward its increase was revealed), the annual mean growth rate of CO2 is 2.34 ?mol/mol per year, its variations range from 1 to 4 ?mol/mol per year. © 2018, Allerton Press, Inc.

Аннотация: A complex approach is considered to the estimation of emissions of carbon gases formed during wildfires in the middle taiga subzone in the Yenisei region of Siberia. Based on the large-scale Siberian wildfires in 2012, the relative contribution of emissions to the values of background concentration of carbon gases (CO2, CH4, CO) in the atmospheric boundary layer measured at the 300-m ZOTTO tall tower is assessed. The degree of ecosystem damage caused by wildfires is estimated depending on their intensity and combustion phase (flame or flameless). Emission factors are calculated for the major carbon gases in wildfire plumes which are the key component for assessing wildfire emissions to the atmosphere. © 2018, Allerton Press, Inc.

Аннотация: Subregional occurrence of fires in Siberian forests and seasonal variations in heat and moisture supply are analyzed. Instrumental data on wildfires registered through satellite monitoring data for the period of 1996-2016 are used. The dynamics of the weather fire danger index (PV-1) and intraseasonal anomalies of the Selyaninov's hydrothermal coefficient (HTC) defining fire occurrence variation are revealed using meteorological data series for the Siberian subregions. The statistical regularities of the dynamics of the weather fire danger index are summarized for subregions. The separated scenarios are formalized by model functions. The projections of the probability of the scenarios' implementation, the fire return period, and the respective relative burned area are determined.

   Перевод заглавия: New look at understanding hydrological role of forest

УДК	630*2+556.5

Аннотация: Статья посвящена раскрытию причин противоречий, существующих в оценке гидрологической роли лесов. Авторы утверждают, что накопление новой информации в отношении, казалось бы, хорошо изученных процессов и явлений обусловливает необходимость пересмотра традиционных взглядов и приводит к получению новых знаний о гидрологической роли лесов. Рассмотрены разные концептуальные подходы к оценке гидрологической роли лесов в различных географических условиях. Системный анализ собственных материалов и литературных данных позволил выявить особенности гидрологического цикла в зависимости от структуры лесов и климатических условий. В работе использованы данные 460 снегосъемок в период максимальных снегозапасов в 212 насаждениях, произрастающих в неодинаковых климатических и лесорастительных условиях. Сопоставление особенностей баланса снеговой влаги лесных и безлесных экосистем в несхожих климатических условиях позволило понять причины противоречивых оценок гидрологической роли лесов. Авторы показали, что в условиях мягких и теплых зим леса по сравнению с безлесными пространствами являются более мощными испарителями снеговой влаги, а в условиях жестких зим с частыми метелями - накопителями снеговой влаги и источниками формирования стока рек. В работе представлена концептуальная модель, описывающая механизмы влагооборота в лесах бореальной зоны, которые определяют особенности влияния лесных экосистем на речной сток в зависимости от геофизического фона.
The article is concerned with the discussion of the reasons for the contradictions existing in the assessment of the hydrological role of forests. The authors believe that the accumulation of new information related to seemingly well-studied processes and phenomena necessitates revisions of traditional views and leads to new knowledge of the hydrological role of forests. Various conceptual approaches to assessing the hydrological role of forests in different geographic conditions are considered. System analysis of the materials obtained by the authors and literature data made it possible to identify the features of the hydrological cycle depending on the structure of forests and climatic conditions. The data of 460 snow surveys in the period of maximum snow reserves in 212 forest stands growing in different climatic and ecological conditions were used. The comparison of the features of snow moisture balance of the forest and treeless ecosystems in different climatic conditions contributed to understanding the reasons for the contradictory assessments of the hydrological role of forests. The authors showed that in the conditions of mild and warm winters, forests are more powerful evaporators of snow moisture than treeless sites and in conditions of severe winters with frequent snowstorms, they are the accumulators of snow moisture and sources of river flow. The paper presents a conceptual model describing the mechanisms of water cycle in the forests of the boreal zone, which determine the features of the influence of forest ecosystems on the river runoff depending on the geophysical background.

Аннотация: Wildfire is one of the main disturbances affecting forest dynamics, succession, and the carbon cycle in Siberian forests. The Zabaikal region in southern Siberia is characterized by one of the highest levels of fire activity in Russia. Time series of Landsat data and field measurements of the reforestation state were analyzed in order to estimate post-fire vegetation recovery. The results showed that the normalized burn ratio time series can be used to estimate forest recovery in the pine- and larch-dominated forests of the Zabaikal region. Multiple factors determine a forest's recovery rate after a wildfire, including fire severity, tree species characteristics, topography, hydrology, soil properties, and climate. Assessing these factors is important if we are to understand the effects of fire on forest succession and to implement sustainable forest management strategies. In this work we used the field data and Landsat data to estimate post-fire vegetation dynamics as a function of several environmental factors. These factors include fire severity, pre-fire forest state, topography, and positive surface temperature anomalies. A regression model showed that fire frequency, fire severity, and surface temperature anomalies are the primary factors, explaining about 58% of the variance in post-fire recovery. High frequency of fire and positive surface temperature anomalies hamper the post-fire reforestation process, while more severe burns are followed by higher recovery rates. Further studies are necessary to consider other important factors such as soil properties, moisture, and precipitation, for better explanation of post-fire vegetation recovery.
