地下水是黑河中游地区主要的供水水源,过去由于开采布局不合理,在全区已形成多个大小不等的降落漏斗,且面积在不断扩大。为了加强地下水资源的管理,合理开发利用和有效保护地下水资源,必须进行地下水资源的调查与评价。根据黑河中游地下水系统的水文地质条件,在概化出水文地质概念模型的基础上,建立了黑河中游地下水资源规划评价的三维数值模型,并针对该地区各含水层地下水水位的控制要求,给出了各含水层的最优开采量,为合理开发利用黑河中游地下水资源提供了科学依据。同时阐述了因地下水位下降而产生的一系列环境问题,强调了黑河中游地下水资源的合理分配利用措施的重要性。
Groundwater is the main source of water supply in the middle reaches of the Heihe River. In the past, due to the unreasonable mining layout, a number of landing funnels of different sizes had formed in the whole region and the area was continuously expanding. In order to strengthen the management of groundwater resources, rational development and utilization and effective protection of groundwater resources, groundwater resources must be investigated and evaluated. According to the hydrogeological conditions of the groundwater system in the middle reaches of the Heihe River, a three-dimensional numerical model of groundwater resource planning evaluation in the middle reach of Heihe River was established based on the conceptual model of hydrogeology. According to the control requirements of groundwater level in each area of the Heihe River, The optimal exploitation amount of each aquifer provides a scientific basis for the rational exploitation and utilization of groundwater resources in the middle reaches of the Heihe River. At the same time, a series of environmental problems caused by the descent of groundwater level are expounded, and the importance of rational distribution and utilization of groundwater resources in the middle reach of Heihe River is emphasized.
