| 摘 要： | 本文通过统计分析法对官司河流域2003年度的大气降雨与3种不同类型森林(马尾松林、桤柏混交林和麻栎林)的树干茎流特征进行了研究。结果表明:该年降雨总量为683.2 mm,主要集中在4月~9月,6个月的总雨量为646.6 mm,占全年降雨总量的94.6%。3种类型森林树干茎流量都和降雨量密切相关,树干茎流量只有在降雨量达到一定临界值时才会出现,此临界雨量阔叶林针叶林;而在相同降雨量情况下,树干茎流量和干流率则表现为阔叶林针叶林;树干茎流量会随着降雨量的增加而增加,建立两者的相关方程,可知其相关性皆以2次多项式为最佳。

| Abstract: | In this paper,researches were conducted on the characteristics of precipitation and trunk stemflow in Pinus massoniana,Mixed Alnus-Cupressus and Querus acutissima forest by means of the regression analysis method.The results showed that in that year the precipitation was 683.2 mm,mostly occurring from April to September.The precipitation from April to September was 646.6 mm which occupied 94.6% of precipitation in that year.The precipitation and trunk stemflow showed a close correlation.The trunk stemflow c... |
