Study on the Water Value Conversion between Economy and Ecology and Countermeasures of Water Resources Distribution for Coordinated Development of Economy and Ecology

Taking Beijing as an example, the paper studies response mechanisms to water quantity and quality of economy and environment, calculates water value and studies the conversion law of water value, measuring the gains and losses of the water conversion between economy and ecology. On this basis of analysis, the paper tries to give some suggestions for water sustainable utilization. The example gives us some conclusions: (1) in Beijing 2000, the water value of economy is more than ecologic, and in the low level of life, the man could pay more attention to economic water use; (2)if 4.04 x 10⁹ m³ used by social economy in 2000 are reallocated between environment and economy, following utility maximum principle, 24.76 million m³ could be used by economy which is far less than actual, comprehensive water price is RMB 8.01/m³ which is more than actual price 2.81, present water price cannot promote water reasonable allocation and sustainable utilization.
