| 摘 要： | 自然灾害造成的损失通常表现在多个方面,为了客观、全面地评估自然灾害,需要综合考虑多种灾情因素,最终才能得到灾害的总体评估结果。综合灾情指数(SDI)是对一系列灾情评价因子进行归一化、加权求和,这样得到的定量化的灾害评估指数,能够综合反映灾情信息。阐述了具有通用性的综合灾情指数,并设计开发了综合灾情指数工具,该工具包括评价因子、设置权重、规范化灾情指数和综合灾情指数4个模块。以汶川地震为例,利用综合灾情指数工具,对地震重灾区的灾害强度进行了综合评估。通过分析评估结果,综合灾情指数的分布真实地反映了受灾的严重程度,显示出该工具具有较好的实用性和有效性。

| Abstract: | Losses caused by natural disasters often manifested in many respects.In order to evaluate natural disasters objectively and comprehensively,we should consider various disaster factors and finally get an overall evaluation result of natural disasters.Synthetic disaster condition index(SDI) is a kind of comprehensive evaluation index which can reflect disaster information.For constructing SDI we normalized series of disaster evaluation factors,got the weighted summation,and then,quantitative disaster evaluati... |
