Особенности формирования почвенного и растительного покрова техногеных ландшафтов Приморского края

Особенности формирования почвенного и растительного покрова техногеных ландшафтов Приморского края

Abstract

Исследованы почвы и растительность техногенных ландшафтов Приморского края. Исследования проводились по формирующимся техногенным катенам представленными отвалами вскрышных и вмещающих пород. Установлено, что во всех зонах эволюция формирующихся почв реализуется в последовательной смене четырех основных типов эмбриоземов: инициальный – органо-аккумулятивный – дерновый – гумусово-аккумулятивный. Их эволюция определяется особенностями развития биологических процессов. Показано, что каждому типу молодых почв сингенетична определенная стадия развития фитоценоза. Установлено, что стадии развития растительности и молодых почв зависят от положения их в рельефе. Наибольшая скорость педогенеза наблюдается в трансаккумулятивных и аккумулятивных позициях техногенных ландшафтов в верхнем корнеобитаемом горизонте. На элювиальных позициях биогеоценозы эволюционируют медленнее. Установлено, что пионерами зарастания являются экологически пластичные виды, способные переносить экстремальные условия техногенной среды.

Soils and vegetation of man-made landscapes Pavlovsk and Luchegorsk brown coal strip mines are investigated. It is shown that to each type of young soils syngenetic a certain stage of development phytocoenosis. The questions of syngenetic formations of soils in connection with the development processes of the restoration vegetation on man-made landscapes are researched. The taxonomic belonging of plants has been defined. The researches were made on technogenic catena. It has been shown that development stages of vegetation and young soils depend on the position in a relief. As a result of vegetation studying on different elements of a relief it is established that the greatest speed of accumulation and transformation of organic substance is observed in transaccumulative and accumulative positions of man-made landscapes The basis of a soil cover of man-made landscapes of Primorsky Territory is made by four types of soil. Their evolution is defined by features of development of biological processes.
