应用无偏对应分析（DCA）及二歧指示种分析（TWINSPAN）对塔里木河流域荒漠河岸林33个植物群落样方资料进行了多元分析--排序和数量分类，并应用植物群落的排序值与环境参数的多元回归分析给出各群落类型的定量环境解释，探讨了该区植物群落的基本类型、生态梯度及其与环境因子的定量关系。结果表明，塔里木河流域荒漠河岸林的群落类型及其分布主要取决于土壤湿度和盐分含量，并可通过环境参数的数字表达式定量的确定

In this paper，33 plant community samples collected from Tarimbasin,Xinjiang were multivariately analyzed by the detrained correspondence analys is （DCA）and the two-way indicator species analysis（TWINSPAN）.The quantitati ve environmental interpretation of various plant community types is given by the multivariate regression analysis which connects the ordination scores with envi ronmental parameters.The primary plant community types,ecology gradients and the ir quantitative relations with the environmental factors were studied.It is shown by the analysis that the community types and their distribution are mainly determined by the moisture and saline gradients of soil.They are quantitatively determined by the mathematical formulas which contains environmental parameters
