黑河干流中游地区地下水多层含水系统动态仿真
Dynamical Simulation for Multilayer Aquifer System at Middle Reach of Heihe River Basin
【摘要】 建立了符合水文地质条件的地下水多层含水层模型,基于多边形有限差分方法,利用观测孔水位和泉流量进行了模型参数率定、识别与验证,结果说明了模型的合理性。现状水资源利用模式下地下水位及水资源量的预报分析说明水资源的持续超采最终会加快地下水位的下降及泉水衰减速度,从而恶化生态环境地质和影响到向下游的输水量,而本仿真模型可作为强有力的辅助工具为水资源管理提供科学的技术支持。
【Abstract】 The multilayer aquifer system characterizing the local hydrogeology conditions was established. Adopting polygon finite different method, the hydrogeology parameters were calibrated by the groundwater level and spring flux and the model audit was carried out. The results can reproduce the dynamic processes of groundwater flow. And also the model forecast was made under the current pattern of water resources utilization. The results demonstrate the continuous groundwater overexploitation will cause groundwater level decline and speed up the decrease of spring flux, which will degrade ecology environment and affect the surface water inflow to the downstream. This established model can be a powerful tool for water resources managers to analyze different scenarios.
