Abstract: ,According to 25 major vegetation in 47 sampling plot presence-absence data from Ebinur Lake wetland nature reserve in Xinjiang, the methods of TWINSPAN and DCA were respectively employed to analyze quantitative classification and ordination of the main plants. The results showed that the main plant species in Ebinur Lake wetland was classified into eight community types by TWINSPAN, and the habitats were similar with each community. The first axis of DCA ordination expresses the gradients of soil humidity, while the second one depicts the height change of elevation. The results of TWINSPAN were corresponding to those of DCA, which indicated that both the methods have good performance in handling the vegetation sparsely in Ebinur Lake wetland. Additionally, it is more practical value to study the lake wetland restoration and protection of plant diversity in arid areas.
