城镇发展与水资源环境的耦合协调机理与测度方法研究——以大清河流域51个县（区）为例
Coupling mechanism and measurement method of urban development and water resources environment: A case study of 51 counties (districts) in the Daqing River Basin
The interactions between the urban development and the system of water resources and environment are complicated. To analyze their coupling coordination mechanism, an evaluation index system was established based on “driving force-pressure-state-impact-response” (DPSIR) framework and the coupling coordination model. Subsequently, 51 county (district) level administrative units of the Daqing River Basin in Beijing-Tianjin-Hebei region in 2015 and 2021 were analyzed by the evaluation index system. The results show that the relationship between urban development and the system of water resources and environment in the counties (districts) of the Daqing River Basin generally presented a higher extent of positive effects than negative effects. However, the urbanization-water relationship was at a low coupling level, with an average coupling degree (C) of 0.40 in 2015 and 2021. Furthermore, most counties (districts) showed the characteristics of urbanization-oriented development, and high level of environmental pressure. The coupling coordination level showed significant spatial differences, with a higher coordination level in the lower reaches of the Daqing River Basin than that in the upper reaches. The results can provide a reference for optimizing the water resources management policy and promoting the sustainable development of the Daqing River Basin.
