长三角城市群水生态绿色网络的空间分布与演化

Research on the Distribution and Evolution of the Green Network of Water Ecology in the Yangtze River Delta Urban Agglomeration

长三角一体化已进入高质量发展阶段,水生态绿色发展是长三角一体化高质量发展的重要组成部分。结合生态承载力的内涵,通过灰色关联分析衡量长三角地区水生态绿色发展水平。在此基础上,运用社会网络分析法,对长三角城市群2006、2012、2018和2021年的水生态绿色网络的空间分布及其演化规律进行了研究,结果表明:长三角城市群水生态环境绿色发展水平存在区域内的差异;长三角城市群水生态绿色网络使各城市的绿色发展联系日益紧密;长三角城市群水生态绿色发展水平整体在不断提升。

The integration of the Yangtze River Delta has entered a stage of high-quality development,and the green development of water ecology is an important component of the integrated high-quality development of the Yangtze River Delta.Based on the connotation of ecological carrying capacity,the green development level of water ecology in the Yangtze River Delta region was measured by gray correlation analysis.On this basis,the social network analysis method is used to study the spatial distribution and evolution of the water ecological green network in the Yangtze River Delta urban agglomeration in 2006,2012,2018 and 2021.The results show that:there are regional differences in the green development level of water ecological environment in the Yangtze River Delta urban agglomeration;The water ecological green network of the Yangtze River Delta urban agglomeration has made the green development of various cities increasingly linked;The overall level of water ecological green development of the Yangtze River Delta urban agglomeration is constantly improving.
