Study on the Relationship between Urbanization and Water Resources Utilization in Daqing River Basin
In order to explore the correlation between urbanization and water resource utilization,the Daqing River Basin where Xiong'an New Area is located was taken as a case study.By establishing an indicator system for evaluating the process of urban-ization and water resource utilization,the coordinated degree model of environment and economic development was used to evalu-ate the urbanization and water resource systems in the Daqing River Basin from 2001 to 2021.The process of two systems and their coupling relationship were analyzed.The results show that:(1)the urbanization level in the Daqing River Basin was increas-ing linearly.Economic urbanization contributed the most to overall urbanization,followed by social and spatial urbanization,while population urbanization was the least;(2)The overall water resources system was greatly affected by the background situation,but it was still increasing with fluctuations;(3)The coordinated development relationship between urbanization and water resources had evolved from severe imbalance and decline to high-quality coordinated development.This study could provide references for sus-tainable development of cities and scientific support for the"four water and four fixed"policy.
