摘　　要：目前应用于水边线提取的方法众多,但是精度、效率参差不齐,本文主要通过对比监督分类、单波段阈值法、归一化指数模型法以及决策树方法在landsat-8影像下鄱阳湖水边线提取的精度及效率,结合水边线提取后的应用对提取方法进行对比分析。There are many methods in water edge line extraction, but the accuracy and efficiency are different. The paper by comparing supervised classification, single -band threshold, MNDWI and decision tree on their accuracy and efficiency ,provides us a better way combined with their using.
