| 摘 要： | 对1996年生长季节中两种落叶阔叶林冠层对降水的分配各分量的测定和分析表明：降水在辽东栎林冠层中的分配为：干流量S，66.7mm；透流量T，539.3mm；截留量I，117.6mm；分别占同期降水量的9.2％、74.5％和16.3％。混交林对降水的分配为：干流量S，32.8mm(4.5％)；透流量T；555.9mm(76.8％)；截留量I，134.9mm(18.6％)。各分量与降水特性的多元回归的结果表明：干流量S与降水量P和前24小时降水量P1之间呈显著正相关关系；透流量T与降水量P和最大雨强M正相关显著。

| Abstract: | Canopy distribution of precipitation and its controlling factors in two deciduous broad leaved forests were measured and analyzed during the growing season in 1996 For the Quercus liaotungensis forest,the stemflow,throughfall,interception were 66 7mm,539 9mm and 117 6mm,amounting to 9 2%,74 5% and 16 3% of the precipitation of 723 6mm,respectively For the deciduous broad leaved mixed forest,the stemflow,throughfall and interception were 32 8mm(4 5%),555 9mm (76 8%) and 134 9(18 6%),respectively The stemflow was positively related to the total precipitation and precipitation during the initial 24 hours,while throughfall was positively related to the precipitation and maximum rainfall density. |
