淮河生态经济带水生态文明发展水平影响因素的时空异质性研究OACHSSCD

Water ecological civilization serves as the foundation for ecological civilization.Studying the key influencing factors and the patterns of spatiotemporal heterogeneity in the development of water ecological civilization is crucial for the Huaihe River Eco-economic Belt to become a demonstration zone for ecological civilization construction within the river basins.Based on panel data from 25 prefecture-level cities in the Huaihe River Eco-economic Belt from 2006 to 2020,this paper utilizes a comprehensive evaluation model to measure the development level and spatiotemporal evolution of water ecological civilization.It further employs the GTWR model to explore the spatiotemporal heterogeneity of its influencing factors.The results show that the Huaihe River Eco-economic Belt exhibits significant non-stationarity in the temporal evolution of water ecological civilization,with the coexistence of spatial path lock-in and transition.The influencing factors demonstrate notable spatiotemporal heterogeneity.Specifically,economic growth generally has a positive effect,decreasing from east to west.Industrialization exhibits an overall negative effect,increasing from northwest to southeast.Population density generally has a negative impact,with intensity varying as downstream、upstream、midstream.Opening-up has both positive and negative effects,with positive effects concentrated in the upstream and negative effects focused on the midstream and downstream,where the intensity of impact in the downstream is higher than that in the upstream.Urbanization has dual impacts,with positive effects centered in the midstream and negative effects mainly in the downstream and upstream,with the downstream exhibiting stronger impact intensity than the upstream.Regions should adopt differentiated strategies based on their actual conditions to enhance the development level of water ecological civilization.
