In this study the main experiment site located between the Pochu ancient mountain at Mudan Township Dongyuan Village and the North Mudan Pool Mountain. It has abundant water resources to form the natural ecological pond. The Dongyuan Village has a large area of the natural ecological pond with a very shallow groundwater table. It therefore needs to protect the natural condition. The present results of studies, the characteristics of an ecological pond covers the influence of the catchment hydrology, soil and plants at the Mudan Township Dongyuan Village of science and technology which includes the amount of precipitation, evapotranspiration, surface runoff and groundwater infiltration. The research indicates that the principal water sources in the wetland from precipitation, and the main outflows output from evapotranspiration and groundwater infiltration. The soil has a low permeability. During the research period from May 1,2012 to September 30,2012 the variation in water level lies between 1.045m to 1.288m in the regulator pool. From water budget view, the amount 38500m3 of the inflow is large than outflow 50500m3 to be a natural wetland.
