摘要
本文根据1954年设置的29块标准地的调查,分析了大兴安岭林区主要森林群落的演替趋势,指出兴安落叶松林是该区的演替顶极,樟子松林是土壤演替顶极,白桦林、黑桦林及蒙古栎林等次生林正向着兴安落叶松林演替。
The succession of the main forest communities in the forest region of the Greater Xingan Mountain has been analysed according to checking of 29 plots which were set up in 1954. It was found that the forest dominated by Larix gmelinii was the climax in this region, the forest Pinus sylvestris var. mongolica was the edaphic climax, and the forest Betula platyphylla, Betula davurica and Quercus mongolica were secondary forests respectively. They are evolving towards Larix gmelinii forest.
