Abstract:

Based on System Dynamic Model and the interaction of ecology-production-living system, the coupling formula of water-ecology-economy coordinated development is put forward. Then the coupling model of water-ecology-economy coordinated development is set up. With dynamic simulation and synthetical adjustment, three available precepts are chosen from lots of experimental precepts, such as water-ecology protecting precept (WEP), water-high economic benefits precept (WEH), water-ecology-economy coordinated development precept (WEE). The gross of water demand in WEE is between that of WEP and WEH. And it takes both economic development and eco-environment protection into account, so economic and ecological benefits are both obvious. It is not the best project according to economic development or ecological protection respectively, but it is the best choice to the sustainable development and the construction of eco-economic zone in Heihe River Basin. So the conclusion is that WEE is the optimal one. It can satisfy the requirement of the water-distributed plan for Heihe River Basin which is decided by China's State Council, and improve the benefits of water utilization at the same time.

Key words: Heihe River Basin, water-ecology-economy, coupling model, synthetical adjustment
