在规划地区水资源的开发、利用和管理时,须综合考虑地表水和地下水资源。然而,不管开采前地下水与地表水之间的补排关系如何,开采后地表水总是补给地下水,亦即使河流迳流量不断损耗。对此,本文讨论了在条带状非均质、有渗入补给的含水层中,当地下水的开采量为恒定时,河流迳流量损耗的过程。 When planning the development, utilization and management of water resources in a region, both surface water and groundwater resources should be taken into consideration. However, surface water is always replenished groundwater, even if the flow of water is constantly depleted, regardless of the replenishment relationship between groundwater and surface water prior to exploitation. In this paper, the paper discusses the process of depletion of flow rate in a strip-shaped, heterogeneous, infiltrated aquifer when the local production of groundwater is constant.
