地下水库调控指标的划分与确定——以那陵格勒河冲洪积扇地下水库为例

Classification and Determination for Regulation Indexes of Groundwater Reservoir——An Example of Groundwater Reservoir in Nalinggele River Alluvial-proluvial Fan

特征水位和特征库容是地表水库调控的重要指标,被引入地下水库调蓄能力的评价体系中广为使用。但地下水库的真实水面实际是一个曲面或倾斜平面,以区域上均一的"特征水位"作为调控指标不尽合理且不易于实践操作。因此,本文提出采用由地下水位等值线构成的"特征水面"作为调控指标代替"特征水位",能够更加科学地给定地下水库的调控标准。以那陵格勒河冲洪积扇地下水库为例,给出了基于地下水流数值模拟的特征水位确定方法以及特征库容的计算过程。

Characteristic water level and characteristic storage capacity is always known as the important indexes for the regulation and storage capacity of groundwater reservoir, it is widely used in evaluation system of groundwater reservoir. For the natural groundwater reservoir, a single uniform characteristic water level isn , t very reasonable to be the regulation index, because the real water surface of groundwater reservoir is curved surface or gradient flat surface. The concept of u characteristic water surface^ which is composed by groundwater level contour was proposed to instead the index of “ characteristic water level” ？ The new index system is more reasonable to give the regulation criteria for groundwater reservoir. Taking groundwater reservoir in Nalinggele River alluvial-proluvial fan as an example, the determination method of characteristic water surface and storage capacity were shown based on groundwater numerical simulation method.
