【Abstract】 Stationary observations on hydrologic essential factors of Cunninghamia lancevlata plantations and grass glade were made from 1982 to 1990 in the middle mountain region of Laoshan in Tianlin County. The results show that the significant hydrographic benefits were brought about by the interception and redistribution of rainfall due to the forest crown, and by the forest crops to increase the litter and water holding capacity to improve the physical characteristics of soil, and the increase of water storage in soil.更多还原
