摘　　要：目前基于TM影像的水体信息提取方法有很多种,但是都很难快速、准确、客观地消除山体或建筑物阴影的影响。对常用的几种提取方法进行了验证论述,并基于孟塞尔(Munsell)HSV色彩变换,构建了新的水体提取模型(WEM:TM2-TM5>0且Sat-Va>0)。结果表明,基于该模型可以很好地消除阴影的影响,准确地提取水体信息。There are many extraction methods based on TM images for getting water body information.However,most of them fail to eliminate the influence of shadow of mountain or building fast,accurately and objectively.The paper discussed and verified several commonly used extraction methods.Based on the Munsell HSV color transformation,a new model of water body information extraction（WEM： TM2-TM5〉0 and Sat-Va〉0） was established.It was testified that by WEM the influence of shadow can be eliminated thoroughly and accurate information of water body can be obtained.
