| 摘 要： | 对塔里木河下游公益林30个样地的实际调查资料，运用二元指示种分析（TWINSPAN）对该区植物群落进行了分类，采用物种多样性指数、丰富度和均匀度指数对塔里木河下游的天然植被的物种多样性进行了分析。结果表明，研究区内的植物区系组成贫乏，群落结构简单，多样性指数和丰富度指数均较低，TWINSPAN程序将30个样地划分为9个群落类型。

| Abstract: | In the lower reaches of the Tarim River,many environmental problems have been brought about by the irrational exploitation and utilization of natural resources,especially water resources,which mainly include the reduction of streamflow of the mainstream,salinization of surface water,stream cutting off,degeneration of vegetation,enlargement of the area of land desertification,unceasing deterioration of ecological environment,etc.Based on the data obtained from 30 plots of natural plant community in the lower... |
