摘要
根据半干旱地区樟子松林冠截留降雨的实测资料,对林冠截留与大气降雨之间的关系进行了分析。在几个假设的基础上,建立林冠截留及林内雨量的半理论半经验公式,并介绍了参数确定方法。经检验,公式的计算值与实测值取得较好的一致性,基本上反映出林冠截留降雨的一般规律,揭示了林冠对降雨截留作用的数量关系和客观实质。
According to the observation data of forest canopy intercepting rainfall in pinus sylvestris var. mongolia forest, the relations between interception and rainfall are analyzed. On the basis of several assumptions, the semi - theoretical and semi - empirical formula about interception and rainfall under forest are established with introducing the methods of setting parameters. The comparisons of calculation values and actual values for interception and rainfall under forest both are good consistency by the testing. The results show the general laws of forest canopy intercepting rainfall.
