| 摘 要： | 基于灾害风险理论及气象灾害风险形成机制,收集宁夏暴雨、灾情资料、社会经济资料、地理信息及遥感数据,综合考虑在形成宁夏暴雨洪涝灾害过程中孕灾环境,致灾因子,承灾体及当地的防灾减灾能力等因素,构建暴雨洪涝灾害风险评价的框架、指标体系、方法与模型,对宁夏暴雨洪涝灾害风险程度进行评价并借助GIS技术进行等级划分和专家讨论,形成宁夏暴雨洪涝灾害风险区划成果。由研究成果得出了经济较发达的整个宁夏平原都属于暴雨洪涝灾害中等以上风险区等诸多结论,为本地区灾害规划与预案制定、重大工程建设、生态环境保护与建设等提供决策依据。

| Abstract: | Based on disaster risk theory and meteorological risk forming mechanism,meteorological data,risk data,social economy data,GIS RS data and so on were collected,and by the comprehensive analysis on multiple factors such as the environment sensitivity pregnant with disasters,hazard formative factor,hazard carrier and capacity of defending and lightening disaster in the process of flood disaster in Ningxia,the frame,index system,means and models of rainstorm and flood risk evaluation were constructed,and by the evaluation of flood risk level,scaling by GIS and panel discussion,the flood risk regionalization results were formed.From the results,it was found that the more developed regions in the whole Ningxia plain were at the high rainstorm and flood risk,as well as many other conclusions,providing the decision rationale of local disaster planning,the emergency plan making,important engineering construction projects,and the ecological environment protection and construction. |
