摘　　要：利用高分卫星遥感数据(GF-1),通过不同流域植被的光谱特征分析,建立解译标志,采用遥感分类方法进行分类,获取流域的植被信息;采用GIS技术,分析不同类型的植被特征对中小流域洪涝灾害发生的影响。结果表明:流域洪涝灾害与地形地貌关系密切,研究结果对开展中小流域洪涝灾害监测有着重要的作用。Based on the spectral feature analysis of different watersheds, high-resolution satellite remote sensing data （GF-1） was used to establish the interpretation markers, and the remote sensing classification method was used to classify and obtain the vegetation information of the watershed. Using GIS technology, different types of vegetation The Impact of Flood Disasters in Middle and Small Watershed. The results show that the floods are closely related to the topography and topography, and the research results play an important role in flood monitoring of small and medium-sized watersheds Based on the high resolution satellite data （GF-1） , the spectral characteristic of vegetation in different basin was analyzed and the interpretation keys were established . The vegetation was classified into different types by using remote sensing classification method and the influence of different vegetation types on the flood were analyzed by GIS. The results shows that： flood disaster were closely related to topography and geomorphology in the basin.
