Spatial Characteristics of Water Quality of Wetland in Northeast China– the Case of Zhalong Wetland

Water quality of wetland has multi spatial distribution characteristics which are the integral impact of pollutant distribution, hydrodynamics field and topography. This article analyzed the hydrochemical field characteristics to indentify the water purification function of Zhalong Wetland. The result indicated that the water of Zhalong Wetland was purified remarkably in the wetland ecosystem.
