Аннотация: В работе рассматриваются вопросы продуктивности сосновых лесов на европейской территории России в связи с почвенно-гидрологическими и климатическими условиями Обсуждаются результаты изучения влияния солнечного тепла, атмосферных осадков, механического состава почв, глубины залегания и проточности грунтовых вод на рости производительность насаждений. Приводится оригинальная методика сбора материалов математического моделирования лесных биогеоценозов. Значительное внимание уделено плодородию лесных почв и разработке земельного кадастра, выявлению общих закономерностей в строении древостоев, динамике фитомассы насаждений. Книга предназначена для специалистов в области лесной экологии, работников лесного хозяйства,преподавателей и студентов лесных вузов.The work dwells upon the problems of pine forests productivity on the European territory of Russia in connection with soil- hydrological and climate conditions. The results of the study of solar heat, atmospheric precipitation, soil texture, ground waters depth of bedding and flowage effect on the stand's growth and productivity are discussed Original technique of material collecting and forest biocenosis modelling is given. Considerable attention has been payed to forest soils fertility and land cadaster elaboration, to revealing the general laws stand structure and stand phytomass dynamics. The book is meant for the specialists in the field of forest ecology, forestry management workers, forestry higher educational istitutions professors and students

Аннотация: This book contains information about carbon storage in the vegetation, soils, and peatlands of Russia, estimates of carbon storage in forests, statistical data from the 1998 national forest inventory of Russia and from other sources. Methods are presented for converting data on timber stock into phytomass of tree stands, and for estimating carbon storage in forest soils and peatlands in Russian's administrative territories and natural ecoregions. Also information is included on the timber stock of Russia's primary tree species and phytomass of forest vegetation, mortmass, and peat

Аннотация: This paper describes a long-term study of aboveground phytomass before and after the clearfelling of two Norway spruce stands. The clearfelled areas were treated in different ways:(1) slash was left in situ, as in conventional forestry; (2) slash was removed, as in whole-tree harvesting; and (3) controlled burning was carried out, as was common practice in northern Sweden about 40 Years ago. The phytomass of the field-layer vegetation was determined 1, 4. 10, and 16 years after clearfelling. The phytomass of the ground-layer vegetation was measured one and four years after clearfelling.
