摘　　要：城市脆弱性研究对实现城市全面协调的可持续发展具有重要的现实意义。基于资源环境、经济、社会三个子系统构建评价指标体系,运用熵权法确定各指标权重,应用加权求和法对江西省11个地级市2010—2019年脆弱性时空格局演变进行了分析,结果显示江西省城市脆弱性整体上呈明显下降趋势。在时间上,11个地级市脆弱性演化历程可分为3个阶段:2010—2012年为较高脆弱主导阶段,2013—2016年为中度脆弱主导阶段,2017—2019年为较低脆弱主导阶段;在空间上,11个地级市脆弱性总体呈日趋均衡的态势,但又具有显著地区差异性,各个城市应对自然、人为干扰要素的能力不断增强。障碍因素分析结果表明,江西省城市脆弱性主要障碍因素分别为空气质量优良率、GDP增长率和人均道路面积。研究结果可为江西省城市可持续发展提供借鉴。The study of urban vulnerability has important practical significance to realize the sustainable development of urban comprehensive coordination.The evaluation index system is constructed based on the three subsystems:resources and environment,economy and society.The entropy weight method is used to determine the weight of each index,and the weighted sum method is used to analyze the spatial-temporal evolution of vulnerability of 11 prefecture-level cities in Jiangxi Province during 2010 to 2019.The results show that the vulnerability of cities in Jiangxi Province has witnessed an obvious downward trend on the whole.In terms of time,the vulnerability evolution of the 11 prefecture-level cities can be divided into three stages:from 2010 to 2012 is a high vulnerability dominant stage,from 2013 to 2016 is a moderate vulnerability dominant stage,and from 2017 to 2019 is a low vulnerability dominant stage.Spatially,the vulnerability of the 11 prefecture-level cities shows an increasingly balanced trend,but there are significant regional differences,and the ability of each city to cope with natural and human disturbance elements is constantly enhanced.The analysis of obstacle factors shows that the main obstacle factors of urban vulnerability in Jiangxi Province are the excellent air quality rate,GDP growth rate and road area per capita.The results can provide reference for the sustainable urban development of Jiangxi Province.
