| 摘 要： | 利用地统计学方法定量研究了额济纳绿洲地下水位埋深的空间异质性.结果表明:额济纳绿洲地下水位埋深分布有较大的空间异质性,地下水位埋深的理论模型为球体模型;额济纳绿洲地下水位埋深主要受结构性因子的影响;地下水位埋深的变程在22.6km左右.地下水位埋深的空间分布总体上表现为从南到北,从西向东逐渐增大的分布格局.局部分布上,...

| Abstract: | Spatial heterogeneities of groundwater level depth was studied with the combination of methods of geo-statistics and spatial analysis function of GIS in the Ejina oasis.Results showed that groundwater level depth had the significant spatial heterogeneity.The spatial variation in groundwater level depth was best fitted by spherical model.Groundwater level depth was greatly affected by structure factors.The variation range of groundwater level depth was about 22.6 km.The spatial distribution pattern of ground... |
