Research on the Evaluation of Water Resources Carrying Capacity in the Central Plains Urban Agglomeration Based on the PS-DR-DP Model

Adequate Water Resource Carrying Capacity (WRCC) is of great significance for the sustainable development of urban agglomerations. Accurately evaluating WRCC is of great significance for the coordinated development of urban agglomerations. Based on the PS-DR-DP framework, an evaluation index system for water resources carrying capacity was established, and the main obstacle factors affecting CPUA WRCC were analyzed using an obstacle degree model. The WRCC index of the Central Plains Urban Agglomeration (CPUA) was calculated using the Improved TOPSIS model, and the evolution and spatial distribution characteristics of WRCC were analyzed. The results indicate that the water resources carrying capacity of the Central Plains urban agglomeration has been coordinated and sustainable in recent years.
