| 摘 要： | 在遥感与GIS技术的基础上，应用数字高程模型(DEM)生成的格网模型进行洪水的淹没分析。在给定洪水水位和洪量两种条件下，对基于三角形格网模型和任意多边形格网模型，分别得出洪水淹没结果。并对洪水遥感监测获得的淹没范围，利用格网模型进行水深分布计算。结果表明，以GIS技术为支持，采用平面模拟方法进行洪水淹没范围和水深分布的模拟是可行的，使遥感监测与一般洪涝灾害损失评估模型比较好地结合，得出更准确的灾情损失评估结果。

| Abstract: | Based on remote sensing technology the GIS grid model generated by digital elevation model (DEM) is utilized to analyze the flood submergence. By means of this method the flooding situation including the extent of flood submergence and water depth distribution is attained, if the flood level and discharge are given. This method combines the remote sensing technology with the model for assessing the flood loss and gives the more precise assessment of the flood loss. |
