通过研究１０年生人工马尾松林生态系统１９９３～１９９４年的水文活动及其伴随着这些活动矿质元素的迁移过程。结果表明：就２年的平均值来看，林内蒸发量占全年天然降雨量的４．０％，林冠截留占２０．８％，地表径流占２７．８％；穿透雨和树干茎流分别占７６．５％和２．７％。其中以穿透雨中Ｋ，Ｐ，Ｃａ，Ｍｇ，Ｚｎ，Ｃｕ，Ｆｅ，Ｍｎ元素的浓度最高，次为地表径流，最低为天然降雨。流域收入大于支出，矿质量盈余８．５２８ｋｇ／ｈｍ￣２。 By studying the hydrological activities of 10-year-old Pinus massoniana forest ecosystems from 1993 to 1994 and the migration process of mineral elements accompanying them. The results showed that in two years, the evaporation in the forest accounted for 4.0% of the annual rainfall, the canopy interception accounted for 20.8% and the surface runoff accounted for 27.8%. The penetration of rain and trunk stem flow Accounting for 76.5% and 2.7% respectively. Among them, the concentrations of K, P, Ca, Mg, Zn, Cu, Fe and Mn were the highest, the second was surface runoff and the lowest was natural rainfall. Basin income is greater than the expenditure, ore quality surplus 8.528kg / hm ~ 2.
