英文摘要	Spatial-temporal variability of soil salinity for each layer was studied according to gravel-sand mulched field located in Jingtai County. The results show that the temporal stability of soil salinity decreases with the increase of soil depth, and the discrete degree of relative deviation between soil salinity and the mean value of each measuring point increases with the increase of soil depth. Representative measuring points could be determined through temporal stability analysis. The mean soil salinity of each period belong to moderate lower variability and the correlation of mean soil salinity and coefficient of variation are high, and there are visible positive correlation relationship exists in soil salinity and soil depth and the correlation coefficient is 0.911~0.986, which demonstrates that soil depth is the determinant of soil salinity. The results of time-space modelling for soil salinity of 0~10cm layer of different period show that the pattern of soil salinity cumulative oversize distribution curve are similar, and there are little difference in simulation value and measured value and the space distribution basic trend equated measured value and the trend of semi-variance is significant. © 2016, The Editorial Board of Journal of Basic Science and Engineering.
