摘要: 本文采用国际通用软件TWINSPAN把科尔沁沙丘41个植物样方按盖度分成5组,每组代表1种沙丘植物群落类型。同时把17个植物种也分为5组,各组植物种从流动沙丘到固定沙丘出现的顺序为:Ⅴ→Ⅳ+Ⅰ→Ⅲ→Ⅱ。

Abstract: In this paper the international current program and-Two way indicator species analysis(TWINSPAN) method were used to analyse the coverage data of sand dune plant community in Horqin. The result shows that 41 quadrats can be divided into 5 groups,and each group indicates one type of community. We further expounded the characteristics of each community. The results show that17 species can be divided into 5 groups and each group shows the sequence from shifting sand dune to fixed sand dune:Ⅴ→Ⅳ+Ⅰ→Ⅲ→Ⅱ.In addition the characteristics of the soil environment inrelation to the type of community were discussed.

Key words: Horqin Sandy Land, Plant community, Quantitative analysis, Two-way indicator species analysis
