Abstract: The dynamics of soil moisture stored in a wasteland and in a forest land in the sub humid climate region of the Loess Plateau was measuerd with neutron moisture meter for three successive years.Within the depth of 0~320cm,the increment of soil water in the test 3 years was respectively -165.7mm,-15.2mm and-115.2mm at the upper and lower position on north slopes and the lower position on south slope of the wasteland.Soil water increased by 17.2mm at the upper position on north slope of the Chinese pine forest land, after>380mm water was consumed yearly by tree transpiration.It is suggested that forest land is essentially different from wasteland in soil water income/expense.The necessity of conducting the approaches for gaining available water of forest land was put forward.
