摘要
Based on the data accumulated through two year research work forest hydrology study was conducted at Lao Shan plantation experimental station of Maoer Shan Forest Farm.The experiment reuslts on detention of precipitation, permeability of stand soil water holding capacity, formation and regulation of runoff are discussed in the this paper. The major results in this study are as follows: (1)the function of forest in intercepting and storing rainwater is the outcome of integrating action of stand and soli, while the thickness of soil layers is the important factor which affects the water intercepting and holding capacity of forest. (2)The larch forest land had higher permeability, its stable infiltration velocity is twice as much as that of grassland. (3) It is proved that the interflow and groundwater runoff are the major forms of runoff occured in larch forest land.
