摘要:
近年来人们对于自然灾害易损性的基本构成已经初步达成了共识,包括暴露性、敏感性和恢复适应能力,但对于其相互关系尚未有过深入的分析。易损性评价中多是将暴露性、敏感性和恢复适应能力等指标杂糅一起,或者虽然分开选择评价指标但在最后评价时依旧作为一体,没有对整个人地系统的内在机理深入分析。针对泥石流灾害,尝试综合分析整个人地环境的暴露性、敏感性、恢复适应能力之间关系及其对易损性的影响,借鉴经济学中的C-D生产函数建立了易损性的评价函数。在近50 a研究区历史灾情的统计分析基础上,确定了暴露性、敏感性的评价指标,并且由累积的各项损失情况确定敏感性评价指标权重,从灾害造成的直接经济损失出发对函数参数进行估计...
Abstract:
Recently the basic parts of natural disasters vulnerability have reached a preliminary consensus, which is including exposure, sensitivity and resilience, but there hasn't been any indepth analysis for its internal relationships. Vulnerability assessment aways mingle the exposure, sensitivity and resilience index together, or although the choice of evaluation index are separate, the final evaluation still as a whole, there is no inherent mechanism of the system analysis. This paper attempts a comprehensive analysis of the debris flow disaster, considering the relationship between exposure, sensitivity, resilience of the coupled human and environmental systems and the influence about vulnerability, with reference to the C-D production function in economics and established vulnerability assessment function. On the basis of analysis the loss of debris flow in the research area nearly 50 years history, the evaluation index of exposure and sensitivity are ascertained, and the weight of sensitivity evaluation index are determined by the accumulated loss of different types, then the function parameter are estimated from the direct economic losses of the disaster. By comparing the calculated results with different parameters, the contribution rate about sensitivity of human social and economic system for region vulnerability is about 0.8, far higher than the geological hazard exposure of the contribution rate of 0.2. Finally, the vulnerability evaluation method of production function is consummated, and then apply it to assess the current vulnerability in the study area, finally some suggestions are put forward on how to reduce the region vulnerability.
