Abstract

Abstract: A series of experimental studies on the main factors of soil and water are conducted at the area of the Three Gorges reservoir, including soil physical characteristics, infiltration characteristics, the relationship between rainfall intensity and infiltration energy, and so on. The results show that the specific weights of soil particles under the different experimental fields are basically same, the value of the specific weights is 2.65~2.70t/m3. The soil density at the forest floors is smaller

Key words: Three Gorges reservoir, soil infiltration, rainfall, experimental study

摘要： 对三峡库区流域的土壤物理特性、渗透特性、降雨强度与渗透能的关系等进行了实验观测研究，结果表明各实验区不同地况下土粒比重基本相同，在2。65~2。70t/m3之间，变化不大；对于土壤密度，林地较小，其次是草地，而裸露地相对较大；林地和草地孔隙率较大，渗透情形良好，孔隙率随着深度的增加而减小。建立了不同地况下降雨强度与渗透能的数学关系式。
