摘要
本文通过统计分析法对官司河流域的马尾松林林冠截留、林内穿透雨以及树干茎流进行了研究。结果表明:在该林分中林内穿透雨量和树干茎流量在降雨量达到一定值后开始出现,并随降雨量的增加而以增加,并呈现线性相关关系。林冠截留量随降雨量的增加,呈幕函数关系上升,最终趋于饱和,而林冠截留率则随降雨量的增加而减少。
In this paper, researches were conducted on the interrelations of crown interception, forest precipitation and trunk stemflow in Pinus massoniana forest by means of the regression analysis method. The results showed that in this forest the forest precipitation and trunk stemflow increased sharply with the rise of rainfall and the rate of crown interception increased in the range of power function along with the rise of rainfall. However, the rate of crown interception showed the opposite trend.
