济宁市地下水库特征参数分析

针对研究区的疏干含水层空间,分析确定了调蓄下限水位、调蓄上限水位以及对应的透支库容和调蓄库容。借助ArcGIS软件分析了库容的空间分布规律。结果表明,研究区地下水库总库容接近7亿m3,调蓄库容超过4.4亿m3,调蓄潜力很大。此外,由于受潜水含水层给水度和潜水水位埋深的影响,各特征库容的空间分布特征不尽相同。这对在地下水开采漏斗区,利用疏干含水层空间进行地下水库规划建设,及区域水资源的可持续开发利用有着重要的实际意义。

Characteristic parameters analysis of groundwater reservoir in Jining city, Shandong province

In cone of depression areas caused by the over-exploitation of groundwater resource,the construction and planning of groundwater reservoir with the depleted aquifer space is of great significance for sustainable development and utilization of regional water resource. In this paper,the author defines the operation of water levels and reservoir capacities. Meanwhile,the spatial distribution of the reservoir capacity is analyzed by the ArcGIS. It can be concluded that the total capacity of groundwater reservoir is about 7×108m3,and the utilizable capacity is more than 4.4×108m3.Furthermore,the spatial distribution of reservoir capacity is different,which is caused by the specific yield and the groundwater depth.
