摘　　要：针对目前洪灾损失评估模型不实用、不准确等问题,作者基于空间信息格网进行了洪灾损失评估研究。首先探讨了空间信息格网的概念;其次分析了空间信息格网的组成,它由洪水特性格网和社会经济展布格网组成;然后选择Intersect叠加分析方法将洪水特性格网和社会经济展布格网进行叠加分析生成进行洪灾损失评估的空间信息格网;最后建立了基于空间信息格网的洪灾损失评估模型;并采用C#和ArcEngine开发实现了基于空间信息格网的洪灾损失评估应用,验证了该评估模型的可行性,从而为洪灾损失评估提供了一种新的方法。In view of that the current flood loss evaluation model is neither practical, nor be accurate, the author conducts a study on flood loss evaluation based on spatial information grid. First the concepts of spatial information grid are discussed. Secondly, the composition of spatial information grid is analyzed, which consists of the flood character grid and social economic exhibition grid, then the intersect overlay analysis method is selected, the flood character grid and social economic exhibition grid generate spatial information grid of flood loss evaluation. Finally, flood loss evaluation model based on spatial information grid is established. Using C# and ArcEngine, we have realized flood loss evaluation＇ s application to verify the feasibility of the evaluation model. It presents a new method for flood loss evaluation.
