Evaluation of coupling coordination and identification of obstacle factors in human-water system of Yangtze River Economic Belt
摘要
Abstract
Harmonious coexistence between humans and nature is a defining feature of Chinese modernization.For the Yangtze River Economic Belt,a critical strategic region for China's socio-economic development,the coordination of its human-water system is vital for ecological civilization,high-quality development,and modernization.Based on the human-water harmony con-cept and the systematic framework of"human-water-land-industry-urban",we developed a coupling coordination evaluation system for the Yangtze River Economic Belt.By using a coupling coordination degree model,we analyze spatiotemporal patterns of the coupling coordination levels of the human-water system in the Yangtze River Economic Belt from 2005 to 2020 and indentify the main obstacle factors.Results revealed:① From 2005 to 2020,the human system's comprehensive level improved steadily,while the water system showed an upward trend but grew slowly during 2010～2015.② The coupling coordination of the human-water system advanced from mild imbalance to near imbalance,exhibiting a"high at both ends,low in the middle"spatial pattern with provincial capitals leading neighboring cities in a static spatial perspective,and widespread growth with significant regional disparities in a dynamic spatial perspective.③ The primary obstacles were identified as per capita water resources,the ecological water use ratio,per capita general public budget revenue,and built-up area.The findings offer critical insights for the high-quality development of Yangtze River Economic Belt and the construction of ecological civilization.关键词
