人类活动影响下城市大气环境的脆弱性评价

摘要

The concept of vulnerability was introduced into the study of regional atmospheric environment,on the basis of the framework of research on the vulnerability of exposure-sensitivity-adaptability,using combination method of geographic information system (GIS),multi-criteria decision analysis (MCDA) and ordered weighted averaging (OWA) method,considering the human activities,atmospheric environment and socioeconomic factors.We constructed a vulnerability assessment model of atmospheric environment based on the influence of human activities.We took Beijing-Tianjin-Hebei region as an example to explore the practicability of the model,and verified the relationship between human activities and vulnerability of urban atmospheric environment.%将脆弱性的概念引入区域性大气环境研究中,在暴露-敏感性-适应能力的脆弱性研究框架(ESA framework)基础上,将地球信息系统(GIS)、多准则决策分析(MCDA)和有序加权平均(OWA)法相结合,综合考虑人类活动、大气环境和社会经济因素,构建基于人类活动影响的大气环境脆弱性评价模型,并以京津冀地区为例验证模型的实用性,以探寻人类活动与城市大气环境脆弱性之间的关系.
