The Equilibrium Analysis of the Metropolis Water Supply and Demand Planning Management

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.
