摘要
通过对地下水系统与生态用水相互作用过程的研究,把生态用水作为重要的用水项目纳入到地下水系统模型考虑范畴,兼顾地下水的经济、环境和生态功能三者统一,在吉林省大安试验区建立了基于生态用水的地下水系统三维模拟与优化管理模型。采用该模型,分别模拟出试验区1998年和1999年地下水系统水资源各项均衡量,并确定了2000年地下水最佳开采利用方案,实现了地下水资源持续高效利用,取得了良好的经济、生态和社会效益。
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.
