摘要

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／ｈｍ２。

Abstract

With the help of a natural watershed

in which the vegetation was the artificial forest of Pinus massoniana with a 10 years old

it had been studied for the hydrological process and the movement of mineral elements. The evaporation in the stand was 4.0% of the annual rainfall

interception 20.8%

runoff 27.8%

throughfall 76.5% and stemfall 2.7%. It was the most concentration of K

Fe and Mn in the throughfall

the surplus of 8 mineral elements in the watershed was 8.528 kg/h㎡ in the average from 1993 to 1994.
