Wetlands are considered as one of the most productive ecosystems on earth, and more vulnerable and sensitive compared to other ecosystems. With the development of the society, wetlands are suffering serious degradation and loss due to intense anthropogenic disturbance, such as wetland pollution, land use, etc. As one of the effective management measurements, regionalization of wetland function is helpful to have resources in a sustainable development pattern. This paper takes Widgeon Lake, in Beijing, as study region, combining with multi-source remote sensing data, wetland investigation, and the field and meteorological observation data, to analyzes natural features of wetland surrounding, rare feature of wetland type, rare feature of wetland species and the impact of human activities on the wetland. On the other hand, the species and species distribution, soil type and soil moisture, vegetation type and vegetation growing feature, soil erosion and land cover are analyzed, in order to implement regionalization of wetland. Consequently, based on the principles of landscape ecology and wetland science, the function division is conducted, and the leading function area is determined based on GIS technique and overlay analyses, correlation analyses, and leading index methods. As to the management district, according to the hydrological situation and the DEM, the supplement region and protection region are marked out firstly. Then the center, buffer and experiment regions are ascertained in the protection region. As to the leading function area, the protection region is divided into bird protection, vegetation protection, water environment, material supplement, recreation and service regions.
