The wetland reserve of Danjingkou reservoir is the typical representation of wetlands transiting from subtropical zone to warm temperate in China. There are abundant resources of zonic and botanic in the studied area. According to existing problems, the protecting and managing measures were suggested as follows: (1) to set up a national wetland reserve; (2) to make use of forestry ecological projects and other projects for soil and water conservation; (3) to develop resource management information system of the reserve. These measures are of significance in ensuring bio-diversity, water quality of the water diversion project at the middle line and economic sustainable development.
