| 摘 要： | 本文用统计分析方法对江西分宜县山下林场杉木、马尾松人工林的林内降雨、林冠截留和树干茎流进行了研究。结果表明:在该林分中林内降雨量和树干茎流量随降雨量的增加而以直线形式增加;林冠截留量随降雨量的增加呈幂函数关系上升。在杉木林内,随郁闭度的增大,林内降雨率和树干茎流率减少,而林冠截留率增大,马尾松林和杉木林相比,林内降雨率和树干茎流率较大,而林冠截留率较小。

| Abstract: | This paper is a report on the interrelations of forest precipitation, crown interception and trunk stemflow in Cunninghamia lanceolata and Pinus massoniana plantations distributed over the hill-foot areas in Fenyi County, Jiangxi Province. The study, worked by means of regression analysis, has shown that in this forest the rate of forest precipitation and trunk stemflow increases sharply with the rise of rainfall; the rate of crown interception increases in the range of power function along with the rise of rainfall. In C. lanceolata plantations, however, the rise of canopy density results in the fall of forest precipitation and trunk stemflow, but the increase of canopy interception. In comparison with C. lanceolata, the forest precipitation and trunk stemflow for P. massoniana are bigger, but its crown interception is smaller. |
