摘要
对刘家峡库区降雨分布、刺槐和侧柏样地林冠截留特征进行了研究,结果表明:降雨主要分布于5—9月,而大暴雨一般集中在7月上旬至8月上旬;刺槐和侧柏样地林内穿透雨量与林外大气降雨量呈明显的线性关系,林内穿透雨量随林外大气降雨量的增加而增加;侧柏和刺槐样地林冠截留雨量与林外大气降雨量呈幂函数关系;侧柏和刺槐样地截留量分别为0.33~9.13 mm和0.37~3.40 mm。
The paper studied the rainfall distribution and the characteristics of canopy interception of Robinia pseudoacacia and Platycladus orientalis sample area in the the Liujiaxia Reservoir area.The outcomes show that a)the rainfall is mainly distributed in the period of May-September and storms usually are concentrated in the period from the early July to the middle August;b)the throughfall rainfall and atmospheric rainfall of Robinia pseudoacacia and Platycladus orientalis sample area show remarkable linear relationship.The throughfall rainfall is increased along with the increase of atmospheric rainfall;c)The canopy interception of Robinia pseudoacacia and Platycladus orientalis sample area shows power function relation with atmospheric rainfall and;d)The interception of Robinia pseudoacacia and Platycladus orientalis sample area is0.33~9.13 mm and 0.37~3.40 mm respectively.
