Abstract

The shortage of water resources is a rigid constraint factor that limits the development of regional economy and society. The purpose of this study is to scientifically calculate the carrying capacity of water resources, taking into account factors such as natural endowment of resources & environment and pressure of social & economic development. Based on the analysis of supply and demand balance, the idea of water resources carrying capacity calculation based on supply-demand balance analysis is constructed, which includes four steps: "resource endowment analysis - pressure state analysis - supply - demand balance analysis - carrying capacity calculation". Taking Julu County of Hebei Province as a case, based on the calculation of water resources supply and demand, and the analysis of supply and demand balance under multi-scenario simulation, the water resources carrying capacity is comprehensively calculated. The results show that, considering precipitation and surface runoff, exploitable groundwater, regional water transfer and reclaimed water reuse projects, the total available water resources at the end of the planning period are 89.11 million m3. After comprehensively popularizing agricultural water-saving irrigation, ensuring domestic water consumption of urban and rural residents and optimizing the water-saving industrial structure, the total water resources demand at the end of the planning period is 76.74 million m3. Through the analysis of the balance between supply and demand, the water resources structure optimization scheme is formed, and the comprehensive carrying capacity of water resources is calculated, including 420,700 urban population, 173,000 rural population, 32,700 hectares of cultivated land, 4,474 hectares of urban construction land, 3,453 hectares of village construction land and 2,401 hectares of industrial land, thus realizing the rigid constraint goal of "determining city, land, people and production by water".
