It was an important precondition for wetland ecosystem health recovery, management improvements, and the sustainable use of resources to carry out an accurate and reasonable urban wetland function zoning. Taking Beijing wetlands as an example, according to the result of the wetlands ecological service functional value evaluation, the method of principal component analysis was used in comprehensive evaluation of urban wetland ecological service functions. Then the space partitioning method of weighted Voronoi diagram was applied, through the main steps of the attribute weights being determined by using Newton-Breaking point model, to build urban wetlands function zoning model based on weighted Voronoi diagram. Based on the method, the typical wetlands patches were selected in the research of a "bottom-up" quantitative Beijing wetland function zoning. The results showed that: firstly, the wetland ecosystem service function of north wetland groups was very important, especially the Miyun Reservoir wetlands comprehensive value indicating the most important role of the wetland ecosystem services in Beijing. Secondly, Beijing wetland function zoning showed a three hierarchical framework, which included 4 wetland functional zones for the first level, 15 wetland functional zones for the second level, and 43 wetland functional important units for the third level in the homogeneous plane space. At last, the function magnitude of value on wetland resources was combined with the spatial relationship in wetland patches, in order to implement wetland function zoning by a double distance constraint on both attribute and space. This research not only promoted the in-depth application on value assessment of wetland ecosystem services in the decision-making management, but also provided technical supports to the urban wetland function zoning, and met the needs of urban wetlands management as well.
