黄河流域兰州段生态环境与高质量发展耦合协调关系研究

环境保护作为新常态时代下我国推进生态流域文明体系建设的关键环节,推进黄河流域地区生态环境治理已成为生态文明建设的重要内容。通过选取我国黄河流域唯一被干流贯通的省会城市兰州市为研究对象,根据2010—2019年黄河流域兰州段统计资料,构建了黄河流域兰州段生态环境及高质量发展水平评价指标体系,并利用熵权法构建耦合度模型,全面解析和综合评估了生态环境与高质量发展的耦合水平特征。结果表明：黄河流域兰州段生态环境水平并不高,呈“恶化-好转-恶化-好转”的态势,而高质量发展水平呈“降-升-降-升-降-升”的波动态势。总体来看,兰州市生态环境与高质量发展协调性有待加强,应充分考虑黄河流域整体性特征,坚持生态保护优先原则,同步推进产业的专业化整合与转型升级,提升城市综合治理能力,在城乡融合发展基础上优化城市功能结构布局,最终实现人居生态环境可持续发展。

Coupling coordination relationship between ecological environment and high-quality development in Lanzhou section of Yellow River Basin

Environmental protection, as a major strategic initiative to promote the construction of ecological basin civilization systems in China in the era of the new normal, has become an important element in the construction of ecological civilizations by promoting ecological and environmental management in the Yellow River Basin region. By selecting Lanzhou City, the only provincial capital city in the Yellow River Basin that is traversed by the river, as the research object and using data from the Lanzhou section of the Yellow River Basin from 2010 to 2019, an index system for evaluating the ecological environment and high-quality development level of the Lanzhou section is established. Then, a coupling degree model is constructed using the entropy weight method to comprehensively analyze and assess the characteristics of the coupling level of ecological environment and high-quality development. The results indicate that the ecological environment of the Lanzhou section is not great, with a trend of “deterioration-improvement-deterioration-improvement”, whereas the level of high-quality development follows the trend “decline-rise-decline-rise-decline-rise”. Generally, the coordination between the ecological environment and high-quality development in Lanzhou must be strengthened. The overall characteristics of the Yellow River Basin should be fully considered, the principles of environmental protection should be adhered to, the professional integration and transformation and upgrading of industries should be promoted simultaneously, the comprehensive urban governance capacity should be improved, and the layout of urban functions should be optimized on the basis of urban-rural integration development so that the sustainable development of the ecological environment for human living can be achieved.
