摘要
本文基于驱动力-压力-状态-影响-响应(DPSIR)模型,以长江中游城市群为研究对象,选取影响城市生态安全的22个指标并结合熵权法和主成分分析法等方法,对2018年长江中游城市群的生态安全进行评价研究。结果表明,长江中游城市群30个城市的生态安全可以划分为临界安全偏较安全、临界安全偏较不安全、较不安全包含少量临界安全和较不安全4个等级。明确区域生态安全水平,可为长江中游城市群的生态文明建设和生态安全保障提供科学依据。
Based on the driving force-pressure-state-impact-response(DPSIR)model,taking the Yangtze River midstream city cluster as the research object,22 indicators affecting urban ecological security were selected and combined with entropy weight method and principal component analysis method to evaluate and study the ecological security of the Yangtze River midstream city cluster in 2018.The results show that the ecological security of the 30 cities in the region can be divided into four levels:relatively safe but critical,relatively unsafe but critical,moderately unsafe including a few critical cities,and significantly unsafe.Clarifying the regional ecological security levels provides a scientific basis for ecological civilization construction and ecological security assurance in the urban agglomerations of the middle reaches of the Yangtze River.
