Abstract：The dynamics of soil water of 5 forest types(Pinus sylvestris var.mongolica,Pinus koraiensis,Larix gmelinii,Fraxinus mandshurica and mixed forest) in the upper reaches of Ashihe River were studied,using the traditional method.The results show that the soil water content under forest is obviously decreased with the depth except Fraxinus mandshurica.In the layer of 0-40 cm,the soil water content of Larix gmelinii,Fraxinus mandshurica,mixed forest,Pinus koraiensis and Pinus sylvestris var.mongolica was 32.91%,28.79%,25.99%,23.64%,18.76% respectively.The soil water content in the growth season follows the law of high-low-high-low,and changes along with precipitation.Forests play an important role in the dynamics of soil water content in the small watershed.
