摘要
正确认识并理清长江经济带水资源、经济社会、生态环境三者之间的协调发展关系,对促进长江经济带的可持续发展具有重大意义。结合长江经济带发展的实际情况,并综合考虑水资源、经济社会、生态环境三者发展的内外部因素,构建了包含30项的水资源—经济社会—生态环境的评价指标体系。同时,基于综合评价指数模型、耦合协调度模型及障碍度模型,对2008-2021年长江经济带11个省(市)系统综合发展水平、耦合协调度的时空演化规律及影响系统耦合协调度的障碍因素进行分析。结果显示:长江经济带水资源、经济社会、生态环境三系统的综合发展水平呈上升趋势,但子系统间省际差异明显,尤以社会经济子系统的差异最为突出;三系统整体始终保持着高水平的耦合状态,且子系统间的相互制约作用越发明显;系统耦合协调度逐年增加,经历了从濒临失调衰退到初级耦合协调的转变,空间上各省(市)耦合协调度发展节奏不一,具体表现为“下游>中游>上游”的分布特征;根据障碍因素分析可知,城市节约用水量、工业污染治理投资额是影响系统耦合协调发展的重要因素。长江经济带未来可在水资源管理与生态环境治理上多下功夫,同时注重经济社会方面的问题,以实现长江经济带的高质量发展。
It is of great significance for the sustainable development of the Yangtze River Economic Belt to correctly understand and clarify the coordinated development relationship among water resources,economic society and ecological environment.Based on the actual situation of the development of the Yangtze River Economic Belt,and considering the internal and external factors of the development of water resources,economic society and ecological environment,a 30-item evaluation index system of water resources,economic society and ecological environment was constructed.At the same time,based on the comprehensive evaluation index model,coupling coordination degree model and obstacle degree model,the spatial and temporal evolution of the system comprehensive development level and coupling coordination degree in 11 provinces(cities)along the Yangtze River Economic Belt from 2008 to 2021 and the obstacle factors affecting the system coupling coordination degree were analyzed.The results show that the comprehensive development level of the three systems of water resources,economic society and ecological environment in the Yangtze River Economic Belt is on the rise,but the inter-provincial differences are obvious,especially the differences of the social and economic subsystems.The three systems as a whole always maintain a high level of coupling state,and the interaction between subsystems is more and more obvious.The coupling coordination degree of the system is increasing year by year,and it has undergone a transformation from near imbalance decline to primary coupling coordination.The development rhythm of the coupling coordination degree of various provinces(cities)is different in space,which is manifested as the distribution characteristics of“downstream>midstream>upstream”.According to the analysis of obstacle factors,it can be seen that urban water conservation and industrial pollution control investment are important factors affecting the coupling and coordinated development of the system.In the future,the Yangtze River Economic Belt can make more efforts in water resources management and ecological environment governance,while paying attention to economic and social issues,so as to achieve high-quality development of the Yangtze River Economic Belt.
