| 摘要: |
| 【目的】探究中原城市群水生态建设现状与演变规律，推进黄河流域生态保护与城市建设的协同发展。【方法】从水动力、水管理、服务功能3个层面构建城市水生态系统健康综合评价指标体系，运用熵值确权综合评价法对河南省位于黄河流域中原城市群的10个地市开展城市水生态系统健康水平综合评价和比较分析。【结果】①万元GDP用水量信息熵值最高，权重最大；②济源市综合评价值最高，其次是郑州市和三门峡市，开封市和新乡市整体水平较差，其余5个地市处于中等水平；③濮阳市2013—2022年城市水生态系统健康水平呈逐年升高趋势，濮阳市城市水生态系统健康状况综合评价指数最高为2021年，2022年略有下降。【结论】万元GDP用水量是影响中原城市群城市水生态系统健康评价的关键，城市群内部水资源利用效率的区域性差异是导致城市发展水平分化的核心驱动因素，缺水性城市在水生态建设中应着力提升水资源状况和组织结构等关键要素的评价水平。 |

| Abstract: |
| 【Objective】 The Central Plains of the Yellow River Basin play a vital role in regional economic development but face increasing challenges from rapid urbanisation and uneven water resource distribution. This study analyses the current status and spatiotemporal changes of urban water ecosystem health in the region.【Method】Treating the urban water ecosystem as a living organism, a comprehensive evaluation index system was established, incorporating hydrodynamics, water management, and service functions. The entropy weight method was applied to quantitatively assess and compare the health of urban aquatic ecosystems across ten cities in the Central Plains.【Result】① Water use per 10 000 yuan of GDP exhibited the highest information entropy and thus carried the greatest weight in the evaluation system. ② Jiyuan City achieved the highest comprehensive health score, followed by Zhengzhou and Sanmenxia, whereas Kaifeng and Xinxiang ranked lowest. ③ In Puyang City, aquatic ecosystem health improved steadily from 2013 to 2022, peaking in 2021 before experiencing a slight decline in 2022.【Conclusion】 Water use efficiency is the most critical factor influencing the health of urban aquatic ecosystems in the Central Plains. Regional disparities in water resource utilization are key drivers of uneven urban development. Water-scarce cities should prioritize improving water resource availability, management structures, and operational efficiency to enhance the resilience and sustainability of their aquatic ecosystems. |
