城市湖泊湿地是镶嵌于城市建成区硬质基底中的湿地斑块，是城市生态系统的重要组成部分，对区域环境具有巨大的调节功能和环境效益。然而在众多类型的湖泊湿地中，由于其面积、形状、位置及环境类型等不同，所发挥的生态效应也不同。本项目以武汉城市为例，采用小尺度指标测试与空间插值相结合的技术方法，对城市湖泊湿地的生态环境效应进行定量化研究，分别测定与分析其在春、夏、秋、冬四季生态效应，探明城市湖泊湿地的面积指数、形状指数（LSI）、位置指数（距城区中心的距离）、环境类型指数（测试点外侧500m范围内非硬质下垫面所占比例）四者与其温湿效应、空气质量（空气负离子、含菌量、粉尘PM2.5，PM10）的相互关系。在此基础上，建立城市湖泊湿地生态环境效应评价指标，系统全面的评价城市湖泊湿地生态环境效应，为城市人类理想聚居环境的建设及合理的城市湿地规划与保护提供科学依据。

As an important part of urban ecosystem, urban lake wetland is a wetland patch which set in hard basement of the urban built-up area. It serves the function of environmental adjustment and ecological benefits on the regional environment. As the area, geometry, location and environmental types of the urban lake wetlands are varying, the ecological effect is different. This project will analyze the effect of urban lake wetland with four descriptors on the temperature(T), relative humidity(RH), negative ion concentration(NAI), bacteria levels(B) and dust concentration(PM2.5,PM10), including the lake wetland area(WA), landscape shape index(LSI), location in reference to a defined city center(DIST), and surrounding non-built-up proportion around 500m of wetland(PB), using individual-scale of quantitative measurement and spatial interpolation respectively in spring , summer, autumn and winter. Datas of land cover are extracted from Landsat8 OLI images of Wuhan city. Further it will establish systematic and scientific index evaluation on the ecological effect of urban lake wetland. This project will provide scientific basis for the construction of human ideal settlement environment and wetland protection and planning.
