摘要: <正>研究黄前库区流域森林主要类型刺槐林和油松林对降雨的截留和分配作用,结果表明:林冠截留量表现为阳坡刺槐林最多,阳坡油松林次之,阴坡油松林最小,刺槐林的最大林冠截留量约11mm,而油松林的林冠截留量可达15mm;刺槐林枯枝落叶物对降水的截留明显优于油松林,其吸附比例可达自身重量的4.2~4.4倍,而油松林只有2.1~2.5倍;林下植被对降水的吸附量为阳坡刺槐林最大,阴坡油松林次之,阳坡油松林最少,但它们之间的吸附比率相差不大。

Abstract: The rainfall recharging and distributing capabilities by the black locust and Chinese pines,the main forest types in Huangqian reservoir area were studied.The results showed that:the recharging quantity by canopy behaves the black locusts standing southward slopethat of Chinese pines on northward slope>Chinese pines on southward slope,but there are only slight differences between the adsorption ratios.
