%X 突发环境事件应急能力评估是提升城市环境风险管理效能的重要基础。本研究以郑州市16个开发区、区(县、市)为研究单元，通过熵值法和层次分析法构建包含3个一级指标、12个二级指标的环境应急能力评估体系，系统分析郑州市应急能力格局、区域特征及影响因素的作用机理，结果表明：(1) 郑州市环境应急能力呈由中心向外围增强的圈层结构，西部的巩义市、新密市及东北部金水区、郑东新区能力最强，东部的中牟县、航空港区处于中等水平，中部的二七区、管城区能力最弱；(2) 各区域能力特征差异显著，中牟县与航空港区在污染源风险防控方面表现优异，管城区、二七区在敏感点密度与黄河排放量上处于劣势地位，新密市、巩义市在应急准备上具备显著优势；(3) 环境应急能力受自然因素与社会经济因素交互驱动，主导因素为登记注册企业数与坡度，工业GDP与登记注册企业数的协同作用最为显著。本研究可为优化区域环境应急资源配置提供科学依据。
Assessing emergency capacity is an important basis for improving the efficiency of urban environmental risk management. This paper takes 16 districts in Zhengzhou City as the research units, and an evaluation system containing 3 first-level indicators and 12 second-level indicators was constructed based on the entropy method and analytic hierarchy process to systematically analyze the spatial pattern, regional characteristics of emergency capability and mechanism of influencing factors of emergency response capability in Zhengzhou City, the results showed that: (1) The environmental emergency capacity of Zhengzhou City showed a circle structure enhanced from the center to the periphery, the western Gongyi City, Xinmi City, Jinshui District and Zhengdong New District in the northeast were the strongest, the eastern Zhongmou County and Air Port District were at the medium level, and the central Erqi District and Guancheng District were the weakest; (2) There were significant differences in regional capacity characteristics. Zhongmou County and Hangkonggang District had excellent performance in pollution source risk prevention and control, Guancheng District and Erqi District were inferior in sensitive point density and Yellow River discharge, and Xinmi City and Gongyi City had significant advantages in emergency preparedness; (3) The environmental emergency capability is driven by the interaction of natural factors and socio-economic factors. The leading factors are the number and slope of registered enterprises, and the synergistic effect between industrial GDP and the number of registered enterprises is the most significant. This study can provide scientific basis for optimizing the allocation of regional environmental emergency resources.
