摘要

利用1988年和2007年TM遥感影像，计算修正归一化差水指数(MNDWI)，通过调整阀值提取成都市城区2年湿地信息。在此基础上分析了湿地的变化和空间分异。研究证明，城市扩张占用大量湿地是导致湿地资源减少的主要原因。在城市化进程中，应加强对湿地的保护，大力规划湿地公园，以改善城市人居环境质量。

Dynamic Monitoring and Evaluation of the Wetland Resource in the Urban of Chengdu City Using Remote Sensing

Using TM remote sensing image in 1988 and 2007, Modified Normalized Difference Water Index (MNDWI) was calculated, and then wetlands information of two years in the urban of Chengdu City was extracted by adjusting valve values. Analyzed wetland change and spatial variation based on above work. Research proved that urban expansion taking up a large number of wetlands is the main reason for the decrease of wetland resources. During the course of urbanization, we should strengthen the protection of wetland and much planning for wetland parks to improve the quality of city human settlements environment.
