Through visiting and investigation the Dongting Lake Little Swan living habits, diet, migration, quantity, main habitat landscape pattern this study obtained the following results: Little Swan habitat suitability was gained by the method of landscape ecology, using 3S technique to map out the Little Swan distribution map as well as water, vegetation coverage, food, road, residents of swans the Dongting Lake wintering habitat of distribution, to determine the weight of influence factors of habitat value by the analytic hierarchy process(AHP), we established the habitat suitability assessment model (HSI), the better for Dongting Lake swans wintering habitat for the analysis of the status quo, and as ecological pre-warning basis;at the same time natural protection area. The paper puts forward the corresponding countermeasures of Dongting Lake wetland, providing a scientific basis for the effective protection and management to carry out the Little Swan habitat.
