中文摘要：

通过对黄土高原山西临汾煤焦铁铸工厂周边农田土壤小尺度60个表层土样的分析测定，采用经典统计学和地统计学理论，研究土壤磁化率和金属Cu、Zn、Fe、Mn有效态含量的空间变异性。结果表明：土壤pH值、低频磁化率、频率磁化率百分含量、有机质、有效Cu、有效Zn和有效Mn含量符合正态分布，而高频磁化率和有效Fe含量符合对数正态分布；除pH值为弱变异外，其余土壤性质为中等变异水平；土壤各属性的半方差函数理论模型能用球状和高斯模型来拟合；土壤pH值和频率磁化率百分含量空间自相关部分起主要作用，由结构因素所引起的变异性占主导地位，受人为因素影响较小；而土壤低频磁化率、有效Cu、有效Zn、有效Fe、有效Mn含量空间变异性主要受人为因素影响较大。

英文摘要：

The spatial variability of soil magnetic susceptibility and available contents such as Cu, Zn, Fe and Mn were analyzed by using classic statistics and geostatistical methods. A total of 60 topsoil samples were collected at smaller sampling scale from the surrounding of the cokery and iron works in Linfen district of Shanxi Province on the loess plateau. The results showed the following： the soil pH values,low frequency magnetic susceptibility, frequency dependent magnetic susceptibility, organic matter, and the available Cu, Zn and Mn etc. are normal distribution, and the high frequency magnetic susceptibility and available Fe are lognormal distribution. The most soil properties studied are moderate variation, and pH value is weak variation. The spherical and Gaussian models are employed to better fitted to semi-variogram of soil properties. The spatial ,：affability of the pit values and frequency dependent magnetic susceptibility are mainly affected by spatial autocorrelation, which exhibits the soil parent material and sedimentary structure are dominant factor. And while the variability of soil low frequency magnetic susceptibility, available heavy metals （Cu, Zn, Fe and Mn） were mainly induced by human activity factor.
