Summary:East Dongting Lake is one of the national nature reserves in China, and an important habitat for the wintering of waterfowls in China, and even, global wetlands. To study the relationships between waterfowl community and environmental factors is of vital significance in providing useful data and necessary information for the restoration of bird habitat. In the winters of 2010 and 2011, a survey was conducted on the wintering waterfowls in East Dongting Lake wetland, and canonical correspondence analysis (CCA) was adopted to reveal the relationships between the distribution of dominant wintering waterfowl species and environmental factors. The partial CCA was also employed to assess the respective importance of environmental factors on the waterfowl species distribution and diversity. The factors including the distance to roads, distance to residents, patch density, number of vegetation types, water area, and sedge area had significant effects on the waterfowl distribution (P<0.05), with the affecting intensit
