磐石市位于吉林省中南部,处在松嫩平原向长白山过渡地带,市区居民生活用水均为地下水,掌握地下水资源量是今后合理开发利用地下水的重要依据。一、地下水资源计算原则与依据(一)计算原则:地下水的形成与分布,受自然地理条件和水文地质条件制约,因此,地下水资源计算和评价中,应以不同水文地质单元为基础,采用不同的计算方法,以提高地下水资源的评价精度。(二)评价依据:1.参数选择与确定:依据机井抽水试验资料计算和选择的水文地质参数有渗透系数K(m/d)、影响半径R(m)、给水度(μ)、降水入渗系数(α)。2.根据地貌及水文地
Panshi City is located in the central and southern part of Jilin Province, in the transitional zone from Songnen Plain to Changbai Mountain. The urban residents’ living water is both groundwater and grasping groundwater resources is an important basis for rational exploitation and utilization of groundwater in the future. I. Principles and Basis for Calculating Groundwater Resources 1. Computation principle: The formation and distribution of groundwater are restricted by natural and geographical conditions and hydrogeological conditions. Therefore, groundwater resources should be calculated and evaluated based on different hydrogeological units and different Calculation method to improve the evaluation accuracy of groundwater resources. (II) Evaluation Basis: 1. Parameter Selection and Determination: The parameters of hydrogeology calculated and selected according to the pumping test data of the well have the permeability coefficient K (m / d), the influence radius R (m), water supply Seepage coefficient (α). According to the landform and hydrology
