| 摘 要： | 湿地具有多种独特的环境功能和生态效益,在维持地球表面生态平衡中起着极为重要的作用,因而受到人们的极大关注.因此如何快速准确的获取湿地基础信息,成为湿地研究的关键.文章以安庆沿江湖湿地为例,通过对研究区TM影像进行HSV、IHS、LBV、K-T等多种变换和采样分析,构建了新的指数和谱间关系,并在此基础上建立决策树模型提取湿地信息.结果表明,该方法能够快速、准确、客观的提取湿地信息,为湿地研究提供精确的基础数据.

| Abstract: | Being unique in various environmental functions and ecological effects,wetlands have been playing an extremely important role in keeping the ecological balance of the earth surface,and for this reason it gets great concern.How to acquire the basic information of wetlands rapidly and accurately becomes very crucial.This paper comes up with a method of getting the information of wetlands,which takes the wetlands along-Yantze and lakes in Anqing city as an example,and various transformation techniques like HSV... |
