摘要
针对溃坝损失评估涉及众多地理空间对象的特点,提出了GIS支持下的溃坝损失评估方法。在分析生命损失与经济损失的基础上,建立了溃坝损失评估模型。探讨了GIS支持下溃坝损失评估的方法与实现过程,并对评估方法中的几个关键问题进行了分析。通过实际应用表明,该评估方法操作性较强,效果较好,具有较强的推广价值。
Considering many geographical spatial objects involved in the process of loss evaluation caused by dam breach, an evaluation method of losses caused by dam breach based on GIS is put forward. On the basis of analysis of loss-of-life and economic losses, the evaluation model of losses caused by dam breach is established. The method and process on the evaluation of losses caused by dam breach according to GIS are discussed in detail. Several key prob- lems in the evaluation method are analyzed. Practical application showed that such evaluation method is easy to operate and good in effectiveness and strong in popularization value.
