Abstract  

Spatial variability of soil magnetic susceptibility and nutrients in Xiangfen, located in southwest of Shanxi province, were investigated with geostatistics methods. The results showed that, the average of soil low frequency magnetic susceptibility, high frequency magnetic susceptibility, frequency dependent magnetic susceptibility, pH, organic matter, total nitrogen and total potassium were 92.54×10-8 m3\5kg-1, 86.93×10-8\5m3\5kg-1, 6.03%, 8.26, 1.94%, 1.02 g\5kg-1 and 2.39%, respectively; the semivariance analysis showed that soil low frequency magnetic susceptibility spatial correlation distances were 14.33 km. The Kriging method was applied to calculate the unobserved points and to generate the contour map. The ratio of nugget/sill was 23.41%, indicating that the spatial variability of the soil magnetic susceptibility was mainly affected by soil parent materials, soil properties and topology factors etc. Cultivation and fertilizer affected soil magnetic susceptibility, but they didn't change soil magnetic susceptibility intrinsic structure.
