Abstract

Abstract:

In order to comprehensively and objectively assess water resources carrying status and provide a theoretical support for sound spatial planning of socioeconomic development, this study reviewed existing research on carrying capacity of water resources and examined the meaning of water resources carrying capacity. An index system for evaluating water resources carrying capacity was constructed considering three key factors—water quantity, quality, and ecology. Physical quantity index was employed in the evaluation of each factor of water resources. Comparing the index values and the evaluation standards, comprehensive carrying status of water resources system can be obtained by considering the situation of the worst factor. Hebei Province was taken as a case study to evaluate the carrying status of its water resources system. Measures and suggestions for managing water resources were proposed based on the evaluation result and overloading cause analysis. Finally, the evaluation method was verified.

Key words: carrying capacity, overloading, water resources, evaluation method, Hebei Province
