摘要：

在样方调查的基础上，对塔里木河下游的英苏、喀尔达依、阿拉干和依干不及麻4个监测断面的样地植被状况进行调查，在2×2列联表基础上，采用方差比率法(VR)，应用联结系数(AC)、c²检验与M.Godron稳定性测度方法对植被群落进行了种间联结分析与稳定性研究，得到如下结论：① 总体相关性检验结果表明，4个断面中没有出现显著正联结的植物群落，塔里木河下游植物群落演替目前尚未达到稳定水平，且阿拉干与依干不及麻断面的植物群落正处于发育初期。② 植物群落种间关系不显著，分布松散，更倾向于独立分布。群落的结构不稳定，存在于同一个样地内种对之间的依赖性不强，个别区域植物群落物种之间存在一定的竞争关系与排它作用。③ 根据已有的种间关系，可将塔里木河下游的植物群落划分为3个生态种组。

Abstract:

On the basis of plot survey, the vegetation status along the four monitoring sections including Yengisu, Karday, Aragan and Yiganbjima in the lower reaches of the Tarim River was investigated. Based on the 2×2 contingency tables, the variance ratio method (VR), correlation coefficient (AC), c²test and M. Godron stability measurement were used to research the interspecific association and stability of the plant communities in the lower reaches of the Tarim River. The test results of the overall correlation revealed that there were no the plant communities with significantly positive associations along the four sections. The vegetation succession in the study area did not reach a stable level yet, and the plant communities along the Aragan and Yiganbjima sections were still at the early developing stage. The interspecific association of the vegetation communities was not significant, the distribution was loose and even independent. Structure of the communities was unstable, and the dependence among the species in the same plot was not strong. There was a certain competition and exclusive effect between the plant species in some plant communities. According to the interspecific association, the plant communities in the lower reaches of the Tarim River could be divided into three ecological species groups.
