Quantitative analysis of regional water resources and secure development of economic and social coupling systems

Abstract

The development and rational utilization of regional water resources (RWR) is an important foundation for achieving comprehensive utilization of water resources and socio-economic progress. Socio-economic development has created necessary conditions and funds for the rational development of water resources, and the two support and constrain each other. Therefore, this article conducts a quantitative analysis of RWR to ensure the sustainable development of the economic and social (EAS) coupling system. An evaluation system was constructed based on feasibility analysis using the principal component analysis theory and entropy method. The results indicated that the interaction between RWR and EAS was relatively strong. In the seven-year survey, the coordinated development of the two showed an upward trend. The coupling and coordination indexes reached their lowest point in 2015 and have shown an upward trend. The coupling index increased by 0.34, and the coordination index increased by 0.21 to obtain a highly coordinated development state.
