摘　　要：该文以新疆三工河流域浅层含水层为研究对象 ,应用地质统计学的原理与方法 ,初步分析了该含水层导水系数与给水度的统计分布与空间相关性。结果表明 :1)该含水层的导水系数服从正态概率分布 ,给水度服从对数正态分布 ;2 )该含水层的导水系数和给水度在南北方向上的相关尺度均大于其在东西方向上的相关尺度 ;3)该含水层的导水性与释水性均为各向异性。The shallow unconfined aquifer in Sangonghe river valley,Xinjiang being taken as investigated area,geostatistical approach is applied to analyze the statistic distributions and the spatial correlativity of hydrogeological parameters of unconfined aquifer.It may be concluded as :1)the statistical distribution of transmissivity of aquifer is submitted to normal probabilistic distribution and that of specific yield is submitted to lognormal distribution;2)the correlation distances of the two parameters in S-N direction are all larger than those in E-W direction;3)the conductivity and the releasing quantity of the studied aquifer are all anisotropic.
