Based on the data collected by random survey of soil moisture in the Loess Hilly Region, the authors analyzed the dynamic characteristics of soil moisture under different landuses. The result showed that landuses made soil moisture in vertical layer quite different. In terrace land, the variational trend of soil moisture in different layers was accordant, that is, the fluctuation of soil moisture in vertical layer was little. Under different landuses, the variation of soil moisture between surface layer (0-30cm) and middle layer (30-100cm) was accordant, and landuse, in terms of the accordant degree, ranks in the descendant order of terrace land, pasture land, forestland, and shrub land. Except pasture land, the grey relational grade of the landuses between surface layer (0-30cm) and deep layer (100-200cm) was least, which means that soil moisture varied remarkably. The grey relational grade of soil moisture in each month was different. In shrub land, except December, the variational trend of soil moisture was similar. By contraries, grass land had the different trend, and the fluctuation of soil moisture in growth season was great. It can be seen that the different landuses resulted in the difference of dynamic characteristics of soil moisture.
