森林植被对红壤坡地土壤水的影响
Effect of forest vegetation on soil moisture in sloping land with red soil
摘要
Abstract
Selecting the typical sloping land of red soil in Taoyuan station of agro-ecology research of Chinese Academy of Sciences, the soil moisture contents were measured by TDR in forest and bare soil and the effects of forest on soil water were analyzed.The results showed that soil moisture content under vegetation canopy was greater than that in the bare sites, and the change frequency of drying and wetting cycles of soil moisture contents was slower than that in the bare sites.Because of the shading of wood leaf layers and litter fall, soil evaporation and the range of soil moisture contents changing were small under forest canopy.Due to the effect of the forest canopy and roots, soil moisture content had a decrease tendency with the increasing distance from tree trunk.关键词
