【摘要】 根据内蒙古大青山山地分布的天然林植被和大规模分布的人工林植被构成的森林生态系统,分别就白桦次生林、华北落叶松人工林、油松人工林和虎榛子灌木林等4个主要森林类型进行了林分生物量与森林群落结构的调查。估算了大青山4种主要森林植物类型地上部分碳储量总量为305.25 t/hm2,为大青山森林生态功能评价提供依据。更多还原

【Abstract】 Based on the forest ecosystem formed by natural forest vegetation and plantation vegetation distributed in large scale in Daqing Mountains,stands biomass and forest community structure have been investigated for Betula platyphylla secondary forest,Larix principis-rupprechtii plantation,Pinus tabulaeformis plantation and Ostryopsis davidiana shrubs.The total amount of aboveground carbon storage is estimated to 305.25 t/hm2 for the main four kinds of forest plant types in Daqing Mountains,which can provide basis for evaluating the forest ecological function.更多还原
