摘要
基于“双循环”视角并结合污水资源化利用,回溯分析了2010—2019年我国29个省(区、市)的水资源利用效率与经济发展两个系统的耦合协调度,并研究了其时空演化趋势。结果表明:2010—2019年水资源利用效率与经济发展水平及耦合协调度随时间整体呈上升趋势,但仅部分省(区、市)逐步向良性协调转变,同时也出现了东部地区的协同水平明显优于其他地区的空间不平衡现象。对此,应提升污水收集处理能力,强化资源共享,加快构建完整内需体系,深化开放格局,推动实现水资源利用与“双循环”新发展格局的优质协同局面。
From the perspective of dual circulation and combined with sewage resource utilization,the coupling coordination degree between water resources utilization level and economic development in 29 provinces(autonomous regions and municipalities directly under the central government)in China from 2010 to 2019 is retrospectively analyzed,and their spatial-temporal evolution trend is studied.The results show that the water resource utilization and economic development level as well as the coupling coordination degree increase with time.However,only some provinces(autonomous regions and municipalities directly under the central government)are gradually transforming to the benign coordination.Simultaneously,the coordination level in the eastern areas of China is obviously better than that in other areas with spatial imbalance.In this regard,we should enhance the capacity of sewage collection and treatment,strengthen resource sharing,accelerate the construction of a complete domestic demand system,deepen the opening pattern,and promote the realization of high-quality coordination between water resource utilization and the new development pattern of dual circulation.
