摘要
通过40年以来滨州地区深层地下水水动力场、水化学场和深层淡水开发利用状况分析,认为深层地下水过量开采形成降落漏斗并引起咸水入侵;采用水化学特征值和同位素资料讨论了深层咸水的成因,在分析了深层地下水开采资源构成的基础上,揭示深层地下水的补给与释水机制,计算了控制水位降速、防止咸水入侵两个约束条件下的深层地下水可开采量2 001.9万m3/a,提出了减少深层地下水开采量、回灌补源等水环境保护措施。
Overexcavation of groundwater led to the cone of groundwater depression and saltwater intrusion analyzing hydrodynamic field, groundwater chemistry field, and the status of exploitation and utilization in deep confined freshwater in Binzhou for more than 40 years. This paper adopts hydrochemistry eigenvalues and isotope data to discuss the causes of formation of deep layer saltwater. On the basis of analyzing the composing of deep confined water exploit-resource, it reveals the recharge and release mechanism of deep-layer confined water. It calculates the allowable yield about 2 001.9 m^3/a of deeply confined water under the constraint condition of controlling groundwater lowering speed and preventing saltwater intrusion. For the sake of rational exploitation and utilization of confined water and to protect our environment, this paper suggests reducing exploitation of deep confined water, moderately utilizing upper shallow groundwater and deep groundwater recharge.
