长江经济带,具有全球影响力的内陆经济区,近年来呈现出繁荣经济发展的趋势。经济发展,水污染,资源枯竭,和其他环境问题继续出现。水生态环境的稳态是生态安全的重要方面。调查区域水生态安全状况,本研究在“驱动力-承载源-状态-管理”(DCSM)框架内构建了综合评价指标体系。采用熵权法确定各指标的权重,并引入加权秩和比模型对2010-2019年长江经济带水生态环境进行分类。最后,对抗性解释结构模型用于细化每个地区的排名。结果表明,承载状态和驱动力子系统与水生态环境密切相关。前三名指标为工业增加值万元的废水排放量,万元工业生产总值用水量,和每万元三次国内生产总值的用水量。此外,长江经济带水生态环境存在明显差异。分类结果表明,浙江、江苏被评为“优秀”;云南,贵州,安徽,江西处于“良好”水平;四川,湖南,重庆,湖北处于“中等”水平。上海是“穷”。“作为一个整体,下游优越,上游是第二,中游在不对称的“U”形分布中较差。在学习期间,长江经济带水生态总体处于中等水平,尚未达到安全稳定状态。以传统工业化为主要发展路径的地区表现较差。因此,今后有必要关注流域整体水生态安全,强化政府水生态管理的监管作用,促进传统产业和资源型地区的改革,实现水生态环境的可持续发展。
The Yangtze River Economic Belt, an inland economic zone with global influence, has shown a trend of prosperous economic development in recent years. Economic development, water pollution, resource depletion, and other environmental problems continue to emerge. The steady state of the water ecological environment is an important aspect of ecological security. To investigate the regional water ecological security state, this study constructs a comprehensive evaluation indicator system within the framework of \"driving force-carrying source-state-management\" (DCSM). The entropy weight method was used to determine the weight of each indicator, and the weighted rank sum ratio model was introduced to classify the water ecological environment of the Yangtze River Economic Belt from 2010 to 2019. Finally, an adversarial interpretative structure model is used to refine the ranking of each region. The results show that the bearing state and driving force subsystems are closely related to the water ecological environment. The top three indicators are wastewater discharge of industrial added value of 10,000 yuan, water consumption per 10,000 yuan of industrial gross product, and water consumption per 10,000 yuan of tertiary gross domestic product. In addition, there are clear differences in the water ecological environment of the Yangtze River Economic Belt. The classification results show that Zhejiang and Jiangsu are rated as \"excellent\'\'; Yunnan, Guizhou, Anhui, and Jiangxi are in the \"good\" level; and Sichuan, Hunan, Chongqing, and Hubei are in the \"medium\" level. Shanghai is \"poor.\" As a whole, the downstream is superior, the upstream is second, and the midstream is poor in an asymmetric \"U\"-shaped distribution. During the study period, the overall state of water ecology in the Yangtze River Economic Belt was at a medium level and has not yet reached a safe and steady state. The performance of areas with traditional industrialization as the main development path was poor. Therefore, it is necessary to pay attention to the overall water ecological security in the basin in the future, strengthen the regulatory role of the government\'s water ecological management, promote reform of traditional industries and resource-based regions, and achieve the sustainable development of the water ecological environment.
