滦河流域内蒙段地下水资源模拟评价分析

Simulation and Assessment of Groundwater Resources in the Inner Mogolian Section of Luanhe River Basin

以滦河流域上游闪电河子流域地下水资源评价为例,阐述了地下水资源评价中水文地质实体辨识,含水层概念模型选择,边界条件的确定,初始水头、含水层底板高程、水文地质参数空间变异性分析及用可视模块化的三维有限差模型(VISUAL MODFLOW)评价地下水资源的全过程。基于地质统计学插值、估值理论,对于MODF-LOW减小误差和简化参数的调节试算过程提出了新的计算思路。

The comprehensive assessment of groundwater resources has been finished in terms of ecology and industry overall arrangement by the research job of scientific allocation of water resources in the ecological constructive area between Beijing and Inner Mongolia. This paper takes the work of simulation and assessment of groundwater resources in the Inner Mongolian section of Luanhe River basin as a example to set forth over views about how to identify hydrogeolocial regime, to choose groundwater model, to determine boundary condition, to study space variation of initial water table elevation, lower confining bed elevation, and hydrogeological parameters and to use VISUAL MODFLOW when assessment of groundwater resources.
