城镇环境事件脆弱性评估方法研究
发布时间：2018-10-30 14:28
【摘要】：近年来,我国环境事件频发,分析城镇在环境事件中表现出的脆弱性是脆弱性研究的新兴领域,也是环境风险评估方法构建的重要组成部分。通过对已有研究中脆弱性构成要素和研究对象的归纳和总结,提出了城镇环境事件脆弱性评估的概念模型和评估框架。结合典型环境事件特征分析和敏感目标识别,从环境系统、社会系统、经济系统三个维度构建了公里网格尺度的城镇环境事件脆弱性评价指标体系,并探讨了指标的选取原则和空间化计算方法。本研究为城镇实地开展环境事件脆弱性评估提供理论依据和方法基础。
[Abstract]:In recent years, environmental events occur frequently in China. Analyzing the vulnerability of cities and towns in environmental events is a new field of vulnerability research and an important part of the construction of environmental risk assessment methods. A conceptual model and an assessment framework for vulnerability assessment of urban environmental events are put forward by summarizing the elements and objects of vulnerability in existing studies. Based on the characteristic analysis of typical environmental events and the identification of sensitive targets, a vulnerability assessment index system of urban environmental events on the scale of km grid is constructed from the three dimensions of environmental system, social system and economic system. The principle of index selection and the method of spatial calculation are also discussed. This study provides a theoretical and methodological basis for carrying out vulnerability assessment of environmental events in cities and towns.
