Dynamic simulation and comprehensive evaluation of the water resources carrying capacity in Guangzhou city, China

Xiaoyan Wang et al.

Summary: The quantity and quality of water resources are crucial to the sustainable development of the social economy, hence the research on water resources carrying capacity (WRCC) has gained significant attention. This study applies a system dynamics (SD) model to establish a dynamic feedback system for the WRCC and conducts quantitative and qualitative evaluation using multiple methods. The results show that water environment protection and water conservation are effective for improving WRCC and promoting coordinated development, while rapid economic development has the worst impact on WRCC and coordination.

Comprehensive Evaluation of Water Resources Carrying Capacity in the Han River Basin

Lele Deng et al.

Summary: This study systematically quantified the water resources carrying capacity (WRCC) in the Han River basin using SPA method, revealing the good performance of the water resources subsystem and the poor performance of the eco-environment subsystem. The future water resources development and utilization model projected an increase in water consumption.

Comprehensive evaluation and influencing factors of urban agglomeration water resources carrying capacity

Yang Zhao et al.

Summary: Appropriate water resources carrying capacity is crucial for the sustainable development of urban agglomerations. This study calculated the WRCC index of the Beijing-Tianjin-Hebei urban agglomeration and analyzed the spatiotemporal heterogeneity of factors affecting WRCC. The results showed that WRCC in the BTHUA is increasing but the carrying capacity index is not high, with nearly 50% of cities still in an overloaded state. The factors affecting WRCC exhibited notable spatiotemporal heterogeneity.

Assessment on water resources carrying capacity in karst areas by using an innovative DPESBRM concept model and cloud model

Tao Peng et al.

Summary: The study established an urban evaluation index system of water resources carrying capacity (WRCC) in karst areas using the DPESBRM concept model, and employed a cloud model for comprehensive evaluation. Results showed a gradual improvement in WRCC over the years. Factors such as population density, urbanization rate, and per capita water consumption were identified as important drivers affecting WRCC.
