Abstract

The chemical properties changes of soil were studied listed as follows:control land, exposed sandy soil, sandy farmland and fixed sandy land in Rangtang County, by the way of spatial sequence instead of the time series. The results showed that:1) Under 0 cm~20 cm and 20 cm~40 cm soil layer, the pH value increased with the increasing of desertification degree; organic matter, total N, the hydrolysis of N,and total P content gradually reduced; 2) Among the same sandy land type of different soil layer, the pH values were not significantly different.Except hydrolysis N of the control soil, organic matter, total N and hydrolysis N, total P content in 0 cm~20 cm soil layer were equal to (approximately equal to) or greater than that in 20 cm~40 cm soil. 3) In different types of sandy soil, no significant change of total K content in the upper and lower soli were found, available K and P content showed as:control land > sandy farmland > expose sandy soil and fixed sandy land.
