Аннотация: Quantitative dynamics, water surface area, and water level of lakes in the Trans-Baikal forest-steppe zone have been studied by spectroradiometry (Landsat satellite), gravimetry (GRACE satellite), and altimetry (Envisat satellite). The number of lakes and their water surface area correlated with precipitation (r = 0.84-0.85), summer and annual temperature (r =-0.77 to-0.9), and drought index (r = 0.95-0.97). During extremely dry periods (2006-2010), the number of lakes decreased by four (compared to 1989) and their water surface area decreased by three (compared to 2000). The rate of change in the water level of the lakes (periods of similar to 29 years) was determined.

Аннотация: Abstract: This paper substantiates the necessity of improving the principles of using natural basis for ecosystem-focused forest management in mountain conditions using all the collected knowledge, regional databases, and new remote sensing facilities. The results of applying the spectral features of vegetation using the thermal range for studying the altitudinal differentiation of forest cover are given based on the example of the mountains of the Altai-Sayan region. Thus, forest-steppe, subtaiga light-coniferous small-leaved deciduous, mountain dark coniferous chern, mountain dark coniferous taiga, and subalpine classes of altitudinal belt complexes (ABC) can be defined in the Yenisei part of the Sayans. Particular forest-management systems should be used for each of them, taking into account the natural features of forests and their management purpose. One important task for mountain forestry and whole multipurpose forest use is to improve the ecological and geographical basis and present it in the form of medium-scale maps, which reflect not only the formational composition of forest cover, but also the altitudinal classes of ecosystems. Modern satellite remote sensing systems coupled with GIS technologies open up new possibilities for forest cover inventory, monitoring, and study methods. This makes it possible to introduce a high-quality natural basis into forest management, which is currently highly relevant at all levels of forest planning: from exploitation projects for separate forest plots to forest plans of federal subjects of the Russian Federation. © 2020, Pleiades Publishing, Ltd.
