| 摘 要： | 本文研究了森林枯枝落叶层抑制土壤蒸发的机制及其与影响因子的关系,结果表明:枯枝落叶层抑制土壤蒸发的效应随枯枝落叶层厚度和土壤含水量的增加而增大。当土壤水分低于11％时,枯枝落叶层抑制土壤蒸发的作用很小。文内给出了枯枝落叶层抑制土壤蒸发与各影响因子的回归方程。

| Abstract: | The mechanism of restraining soil evaporation by forest litter and the relationships between soil evaporation and its influencing factors are analysed in the paper. The results show that the efficiency of restraining soil evaporation by litter is increasing with the increase of litter thickness and water content in soil. The effect of restraining soil evaporation by litter is quite small when the water content in soil is less than 11%. The regression equation between restrained soil evaporation and its influencing factors is also given in the paper. |
