摘要

为进一步保护塔里木河流域胡杨林,对该流域胡杨群落物种种类及数量组成特征、群落高度级物种组成性状进行研究,结果表明:胡杨群落中具有明显的分层性,其结构较简单,最主要的分层为乔木层、灌木层、草本层。塔里木河上游胡杨群落物种数量特征为灌木层>乔木层>草木层,中游为草本层>灌木层>乔木层,下游为灌木层>乔木层>草本层。中游群落中所含的物种个体最多,密度最大;其次是上游;下游所含物种最少,密度最小。
        In order to further enrich the basic data of Populus euphratica community in the Tarim River,the species and quantitative composition of the Tarim River,and the species traits of the community were studied. Result shows that: There is obvious stratification in Populus euphratica community,and the structure of Populus euphratica community is relatively simple. The most important stratification is arbor layer,shrub layer & herb layer. The species characteristics of Populus euphratica community in the upper reaches of Tarim River is: Shrub layer > arbor layer > grass layer. The species characteristics of populus euphratica community in the middle reaches of Tarim River is: Herb layer > shrub layer > arbor layer. The species characteristics of populus euphratica community in The downstream of Tarim River is: Shrub layer > arbor layer > herb layer. The comparative analysis of the individual density of Populus euphratica community shows that the mid-stream community contain the most species & highest density,follows by the upstream; the least species &lowest density are the downstream.
