Most of the metropolis faces the water supply and demand management problem including the surface water pollution, groundwater overdraft, deficiency of water supply, and low efficiency water resource in the past decades. As the Chinese capital, Beijing has been trying to solve the unbalance. This paper describes the water resources equilibrium related with the urban population and the primary method is the equilibrium analysis of the water supply and demand. The elastic scenario output means the water consumption of ten thousand Yuan output value of the primary industry is most sensitive. The case shows building equilibrium equation may be a succinct and practical estimation method for the metropolis.

In order to comprehensively evaluate the water resources carrying capacity in Xiong’an New Area, a system dynamics (SD) model was established to evaluate the regional water resources carrying capacity, for which several scenarios were designed: the original development scenario, the accelerated industrialization scenario, the environmental governance scenario, and the optimization development scenario. The results show that, compared with the original development scenario, the water resources carrying capacity in Xiong’an New Area can be improved in other scenarios, but a water supply and demand gap will be generated due to the lack of groundwater overdraft and a water transfer project. In 2026, under the accelerated industrialization scenario, the population carrying capacity will be 2.652 million, and the water supply and demand gap will be 1.13 × 108 m3; under the environmental governance scenario, the population carrying capacity will be 2.36 million, and the water supply and demand gap will be 0.44 × 108 m3; under the optimal development scenario, the population carrying capacity will be 2.654 million, and since the supply of water resources will be greater than the demand, there will not be a gap between supply and demand, making it the most feasible scenario to effectively alleviate the tension between industry restructuring, environmental management, and water resources development and utilization. The findings of this study can provide reference and decision support for optimizing regional water resources allocation and enhancing water resources carrying capacity in Xiong’an New Area.
