The Zoige Plateau peatland,which is located in the key area of biodiversity conservation in China,is an important representative type of wetland and has valuable wetland resources. With the increase of human activities and global climate change,the wetland degradation is serious and the plant diversity is also affected. The changes of wetland plants and the status of aquatic plants in Zoige were analyzed,The results show that the plant community of Zoige wetland is successively evolved from aquatic to terrestrial. At present,the species number of aquatic plant in Zoige are few and the distributive area of aquatic plant is small. Aquatic vegetation in Zoige wetland show a trend of gradually decrease and community composition tend to single dominant species. In addition,the diversity of aquatic plant in each region of Zoige differ obviously. The diversity of aquatic plant in whole Zoige is low. Accordingly,the corresponding protection strategy is put forward.
