Abstract:

In this paper, infiltration model, formula of soil water movement and interflow in forestland were introduced and analyzed contrastively, and the advantages and shortcomings were pointed out. Meanwhile, the significance of research on soil water movement in forestland was stated that would help for the calculation of water cycle and the reasonable utility of water resources. The prospective tasks of this field were directed clearly, which is to study the laws of water movement in forestland based on the changing rainfall intensity, changeable bulk density and big basin.

Key words: soil water in forestland, infiltration model, soil water movement in forestland, interflow
