Evaluation of the water resources carrying capacity in Shaanxi Province based on DPSIRM–TOPSIS analysis

Year: 2025

Abstract: The evaluation of Water Resources Carrying Capacity ( WRCC) is an important guide for regional economic and social development planning. Based on the Driving Force–Pressure–State–Impact–Response–Management (DPSIRM) conceptual model, this study constructed a 22-indicator system covering the WRCC of Shaanxi Province, and used the Technique of Ordering Preferences for Similarity to Ideal Solutions (TOPSIS) model to comprehensively assess the WRCC of Shaanxi Province from 2012 to 2021. An in-depth analysis of the main obstacle factors of WRCC in Shaanxi Province was carried out by means of the obstacle degree model, and a strategy for optimizing the balance of regional WRCC was proposed. The results show that: (1) the level of WRCC in Shaanxi Province from 2012 to 2021 generally showed an upward trend, with a lower level of WRCC during 2012–2018, and gradually improving level from 2019 to 2021; (2) regional differences are apparent, with the WRCC level in Qinba Mountain significantly better than that in the Guanzhong Basin and Loess Plateau, with the WRCC of Xi'an, the provincial capital, improving from 0.2607 in 2012 to 0.6136 in 2021; (3) daily urban wastewater treatment capacity, total water resources, and water production modulus are obstacle factors that most significantly affect the improvement of WRCC in Shaanxi Province. The results of the study can provide a reference for the optimal allocation of regional water resources.
