【 摘 要 】

Taking Pinus massoniana forest, maple-camphor mixed forest, Eucommia ulmoides forest and slope cropland as the research objects, research has been carried out on the dynamic change of soil moistures at the soil depths of 7.5cm, 12cm and 20cm before and after typical rainfalls. The result indicates: (1) at the 3 soil depths, the soil moistures under typical vegetation forms rank as follows: Eucommia ulmoides forest > maple-camphor mixed forest > Pinus massoniana forest > slope cropland; (2) before and after rainfall, soil moisture content has negative pertinence with wind speed and temperature, while soil moisture content has positive pertinence with humidity.
