本文通过对一个温带－针阔叶林草原生态系统的调查研究得出，在人类强烈的生给活动影响下，山地针－阔叶林被的演替依坡向、坡度和海拔高低呈如下序谱：在北向坡，原Ｐａａｔｓｔａｂｕｌａｅ－ｆｏｒｍｉｓ—Ｓｉｎａｒｕｎｄｉｎａｒｉａｎｉｔｉｄａ群落由高而低依次变为Ｂｅｔｕｌａａｌｂｏ－ｓｉｎｅｎｓｉｓ－Ｓｉｎａｒｕｎｄｉｎａｒｉａｎｉｔｉｄａ，Ｂ．ｐｌａｔｙｐｈｙｌｌａ─Ｐｏｐｕｌｕｓｄａｖｉｄｉａｎａ，Ｑｕｅｒｃｕｓｌｉａｏｔｕｎｇｅｎｓｉｓ－Ｑ．ｓｐｉｎｏｓａ，Ｐｉｎｕｓａｒｍａｎｄｉｉ－Ｔｉｌｉａｐａｖｃｉｃｏｓｔａｔａ，高杂灌；而在南向坡，依次为亚高山禾草——莎草科草甸—Ｓａｌｉｘｐｕｒｐｕｒｅａ灌丛、Ｓａｌｉｘｐｕｒｐｕｒｅａ—Ａｒｔｅｍｉｇｉａｔａｎｇｕｔｉｃａ、农耕地、裸岩一砾石坡。其总的演进趋向是：生境依次变干，植物量依次减少，土壤肥力依次降低，种的多样性经历着由“较单一到复杂再到单一”的贫化过程。
Based on the investigation of a temperate-coniferous and broad-leaved forest grassland ecosystem, the succession of mountain acacia-broadleaf forest under the influence of human’s intense biological activities is as follows Spectrum: On the north slope, the original Paatstabulae-formis-Sinarundinarianitida community turns from high to low into Betulaalbo-sinensis-Sinarundinarianitida, B. platyphylla -Populus davidiana, Quercusliaotungensis-Q. Spinosa, Pinusarmandii-Tiliapavcicostata and Pinus armandii-Tiliapavcicostata, respectively. On the south slope, the order was subalpine grass-Cyperaceae -Salixpurpurea shrub, Salixpurpurea-Artemigiatangutica, farmland and bare rock-gravel slope. The general trend of their evolution is: Habitat turn dry, followed by the reduction in the amount of plants, soil fertility in turn reduce the species diversity experienced by the “more complex to single from the single” of the depletion process.
