A case study was conducted in Hongze County. A scheme combining a storage pond,corridor,facultative pond,and surface flow wetland was determined. The treatment process and the landscape construction were combined to build a comprehensive demonstration project with integration of ecology, landscape, recreation, education, and other functions. The collection,treatment,and utilization of tail water were also conducted.
