宁夏银川北部灌区浅层地下水库调蓄

Regulation in the irrigation of North of Yinchuan groundwater reservoir

将均衡法和有限单元法相结合,对宁夏银川北部溉区地下水库的调蓄进行了开采方案的拟定和模拟计算.以现有开采量0.3亿m3/a为基数,从开采量和地下水位预报方面进行计算分析.结果表明,把第27a的预计开采量11.36亿m3/a作为该方案的最大可开采资源.为制定详细的地下水开发利用规划提供了依据.

The method of combining the groundwater blance method and the finite element method, water balance with numerial simulation has been put forward for regulation of north of Yinchuan irrigation district groundwater reservoir. Taking the existing mining of 30 million m^3/a as a base, from the exploitation of underground water level forecasts for analysis, drawn, the first 27 years of extraction volume is expected to 1.136 billion m^3/a as the programme can be the greatest exploitation of resources. Parameter and exploitation scheme of plan shallow underground reservoir have been fully studied.
