| Spatial variability of soil electricity conductivity (EC) in slope farmland of Zhongliang Mountain under different precipitation intensity (no rain, light rain, miderate rain and heavy rain) was analyzed by classical statistics and geo-statistics, and the correlation of soil EC and related parameters were also processed. The results showed that in some condition, soil EC of pore water and soil water content were the two major factors affecting soil EC. The soil EC was significantly different from each other in both the same soil layer under different precipitation intensity and the soil profile. The fitting precision of semi -variance of soil EC was as high as acceptable. There was a moderate or strong spatial correlation with largest autocorrelation range of soil EC under no rain condition. The C0/（C+C0）of soil EC in 0~10 cm soil layer was 0, while 10-30 cm and 30-50 cm of soil layer had a different degree of decreasing under rain condition. |
