摘　　要：以江苏省东山镇为例,对利用GIS技术估算洪水淹没损失的方法进行了研究,提出了以1:10000地形图数字化数据作为建立DEM的原始数据,对不同区域按不同等高距内插加密提高DEM精确度,通过Supermap栅格计算功能计算洪水淹没范围和淹没深度,并根据居民经验和调查、统计所得的损失率估算洪水淹没损失的方法。It is a widely concerned issue that the loss caused by the flood, during which areas covered by the flood, the depth as well as the land-use together have significant influence of the loss. This essay will probably provide a way to estimate the approximate loss of flood taking those factors mentioned above. With the help of Supermap, we can approach that goal which would benefit the government as a way to provide data for reconstruction after flood.
