Based on field investigation and indoor analysis,the results showed thatOn the Loess Plateau region, recovering vegetation can improve remarkably the content of soil organic matter and available N,K etc.,and drop soil pH and bulk density,add the quantity of waterstable aggregate of soil,improve the productive capability of land,enhence the process of humification and illimerization;Available nutrients,clay and>0.25 mm aggregate are all rich in high forest land,however,bush grass land shows more acid and>0.05 mm microaggregate and less solidity.The benefit of high forest land is better than that of bush grass land in preventing soil deterioration.
