前言降水,通过森林植被到达地表,又沿着地表的倾斜面往下移动,其中一部分水分渗入土壤,保持在土壤孔隙中并在孔隙中流动,形成中间流,这就是地下水,汇集到河川中流出森林地带。渗入土壤的水分,一部分经树木,草灌的根系吸收后蒸发,另一部分从地表蒸发。森林土壤中水分的移动,保持,怎样理解水分的移动?对森林的木材生产机能和水资源的保持机能与土壤中有关水分的分配了解是基本的,也是重要的课题。
Precipitation Precipitation, through the forest vegetation to reach the surface, but also along the slope of the surface down to move some of the water infiltration into the soil, remain in the soil pores and flow in the pores, the formation of an intermediate flow, which is groundwater, pooling into the river outflow Forest zone. Water infiltration into the soil, part of the roots by the trees, grass irrigation after evaporation, the other part of the evaporation from the surface. How do you understand the movement of moisture in the forest soil? How do you understand the movement of water? Understanding of the forest’s timber production function and the retention of water resources and the distribution of water in the soil is basic and important.
