Abstract

Through collecting the soil samples from desert area, desert-loss transitional area, and loss area, which are located in a meridional desert-loess transition zone in north Loess Plateau, we analyzed the soil bulk density and grain-size. The results showed that: (1) Ddesert>Ddesert-loss>Dloss, and the average soil bulk densities were 1.53 g·cm-3, 1.51 g·cm-3, 1.41 g·cm-3 for the three sub-areas, respectively, which had a transitional trend. (2) Medium and fine sand were higher in the desert area, fine sand was higher in the desert-loess transitional zone, while fine and silty sand were higher in the loess area. From the desert area to the loess area, the soil grain size became smaller; the content of clay particle increased; the sorting gets worse; the skewness belonged to a right skewness but having an increasing trend; the kurtosis changed from mesokurtic to leptokurtic. It was single-kurtosis in the desert area, and it is double-kurtosis in the transitional zone and loess zone.

Key words: desert-loess transitional zone soil bulk density grain size
