Diversity of Wild Plant in the Wetland of West Dongting Lake Investigated during the Over wintering

We statistically investigated the diversity of wild plants in the wetland of West Dongting Lake during the overwintering period in 2008-2009 based on the approach of spot sampling in this research.The results showed that the vegetation types are abundant in the wetland of West Dongting Lake during the overwintering,there are seventy three species which might be assigned to twenty nine families have been found in this area,in which compositae and cruciferae would be as the main habitants.The statistical data generally demonstrated that the wild plant communities in the wetland of West Dongting Lakein are characterized by rich variety,homogeneous distribution,and large possibility of encountering other species,which all together illustrated the diversity of wild plants in this area.To some degree,this paper provides a scientific basis for the protection of the diversity of wild plant in the wetland West Dongting Lake,located in the Hanshou county,Hu'nan province,China.
