摘要: <正>对苏北海堤主要防护林类型林冠层降水分配格局及其影响因素的分析结果表明:各林分冠层在降水分配格局方面有较大差异,柳杉林冠层截留率(29.4%)>水杉林(25.7%)>刺槐林(17.5)。透流率则是刺槐林(75.7%)>水杉林(68.2%)>柳杉林(66.0%)。刺槐林和水杉林树干径流率明显高于柳杉林,分别为6.35%、6.1%和4.65%。各林分冠层截留率随降雨量级增大而递减。水杉、刺槐林在落叶期截留率比柳杉林低20%,盛叶期柳杉林与水杉林相近,比刺槐林高10%~15%。另外,在逐步回归分析基础上,筛选出了影响林冠截留的主要降水特性因子,并给出了各林分冠层降水截留量预报模型。

Abstract: Through a study on the patterns of rainfall redistribution in main shelter-forest canopies and their influential factors in Northern Jiangsu Province’s seawall, this paper present the research results as follow: the inter-ceptional rates of these shelter-forests are Chinese cryptomeria(29. 4 %)> Water fir (25. 7% )> Black locus (17. 5%), but the throughfall rates and stemflow rates of these three forests are Crypetomeria(66. 0%)
