本文主要研究内容
作者陈冲（2019）在《村镇综合灾害风险评估研究》一文中研究指出：我国自然灾害频发,而且同一个区域内灾害更是呈现出多样性特征,多灾种风险评估问题受到越来越多学者的关注。相较于城市,我国70%以上的受灾地区为村镇,村镇灾害多发、频发,而防灾减灾能力薄弱,在同等灾害破坏的情况下,村镇的损失远大于城市。因此,基于村镇多灾种的风险评估研究亟待开展。目前,国内外综合灾害风险评估方法大多针对城市。结合我国村镇灾害现状,引入可拓学,提出基于指标体系的村镇综合风险评估模型。识别村镇主要灾害类型,了解村镇灾害特征。通过比较两种典型的灾害风险定义,得出适合村镇的灾害风险系统由灾害危险性、村镇暴露性、村镇脆弱性和防灾减灾能力四准则组成。对各准则层的影响因子进行分析,建立了包括16个3级指标的村镇综合灾害风险评价指标体系,并采用向量夹角余弦法来计算指标权重。引入可拓学构建村镇综合灾害可拓物元系统,并制定风险评估标准以及可拓经典域和节域,进而构建了基于可拓学的综合风险评估模型,对村镇灾害综合风险进行量化研究。应用构建的评价指标体系和评估模型,对某县级市19个乡镇进行灾害综合风险评估,得到每个乡镇的风险评定等级以及级别变量特征值。评估结果和乡镇实际风险情况基本吻合,验证了评估方法合理可行,且具有一定适用性,能为村镇防灾减灾的规划提供依据。图12幅;表6个;参118篇。
