Abstract:

Through the study of mutual process between groundwater systems and eco-environmental water demand, eco-environmental water demand is brought into groundwater systems model as the important water consumption item. In addition, the unification of groundwater's economic, environmental and ecological functions were taken into account, hence a three-dimensional simulation and optimized management model of groundwater based on eco-environmental water demand at Da'an in Jilin province was established. All water balance components of groundwater systems in 1998 and 1999 were simulated with this model and the best optimal exploitation scheme of groundwater systems in 2000 were determined, so that groundwater resources was efficiently utilized and good economic, ecological and social benefits were gained.

Key words: groundwater systems, eco-environmental water demand, three-dimensional simulation model, optimized management model, ecologically fragile area
