运用地统计学方法，选取西安市主城区58口潜水观测井1984年、2000年和2010年地下水埋深资料，分析了地下水埋深的空间变异性和变化规律。结果表明，3个年份地下水埋深具有中等空间相关性，1984—2000年地下水埋深空间相关距离变短，地下水埋深的空间连续性较差，2010年空间相关距离增加，异性比从1984年的0．80减小到2000年的0．24，表明地下水埋深空间各向异性增强；2010年异性比增大到0．65，说明地下水埋深的空间分布各向异性减弱。Krig-ing插值结果显示，研究区地下水埋深呈随地势高程而异的空间变化规律，增加幅度较大（0．30～0．61 m／a），空间变化明显，其变化主要受开采强度的影响。

Using geostatistical analysis method and selecting the groundwater depth data of 24 monitoring wells in the year of 1984,2000 and 2010 as the sample data of Xi'an,this paper analyzed the downtown spatial variation of groundwater depth and the change of rules. The results show that the three years have moderate spatial correlation and poor spatial continuity of groundwater depth,spatial autocorrelation distance is shorter of groundwater depth from 1984 to 2000 and to 2010,the spatial autocorrelation distance increases and the heterogeneity is declined. Anisotropy has been decreased from 0. 80 in 1984 to 0. 24 in 2000,which shows the downtown groundwater depth space anisotropic enhance-ment;anisotropy has been increased 0. 65 in 2010,which shows the spatial distribution groundwater depth anisotropy weakened. Kriging in-terpolation result shows that the study area of groundwater depth in space changing rule of terrain elevation varies,water sources of groundwa-ter depth increase amplitude is bigger;annual increase of 0. 30-0. 61 m/a,space changes obviously and groundwater depth changes mainly affected by mining intensity.
