平顶山市地下水资源分布及开采潜力研究

Study on Distribution and Exploitation Potential of Groundwater Resources in Pingdingshan City

研究区地下水分布广泛,资源量大,开发利用程度高,全区共有四种类型的地下水,即松散岩类孔隙水、碳酸盐岩类裂隙岩溶水、碎屑岩类裂隙孔隙水和基岩裂隙水,多年平均地下水资源总量82 468.14万m^(3),可开采资源量72 435.88万m^(3),地下水资源空间分布不均,含水层富水性差异明显,现状条件下地下水开采系数为0.85,处于采补基本平衡状态。通过研究为地下水资源的保护和合理开发利用提供了科学依据。

Groundwater in the study area is widely distributed, with a large amount of resources and a high degree of development and utilization. There are four types of groundwater in the study area, namely, loose rock pore water, carbonate rock fissure karst water,clastic rock fissure pore water and bedrock fissure water. The annual average total amount of groundwater resources is 824.6814million m;, and the exploitable resources are 72 4.3588 million m;. The spatial distribution of groundwater resources is uneven, and the water abundance of aquifers is obviously different. This study provides a scientific basis for the protection and rational development and utilization of groundwater resources.
