摘要
应用相关分析方法对泰山罗汉崖林场9个典型林分类型的林冠截留特征进行研究。结果表明:林内降雨量与林外降雨量呈很好的线性关系,林冠截留量与林外降雨量呈较好的对数关系;9个典型林分类型对降雨的截留能力为五角枫>麻栎+黑松>15 a麻栎>刺槐>50 a麻栎>黄连木>黄连木+刺槐>侧柏>黑松;7个典型林分类型形成树干径流的能力为15 a麻栎>50 a麻栎>黄连木>五角枫>黑松>刺槐>侧柏;各林分类型总体产生林内降雨的林外降雨量临界值为6.28 mm。
The interception characteristics of nine typical forest stands in Luohanya forest farm of Mountain Tai were studied.The results showed that very good linear relationship existed between through rainfall in stand and open field rainfall.There was a good logarithmic relationship between interception and open field rainfall.The interception capacity of the nine forest stands decreased in the order of Acer mono,Quercus acutissima＋Pinus thunbergii,15a Quercus acutissima,50a Quercus acutissima,Pistacia chinensis,Pistacia chinensis＋Robinia pseudoacacia,Platycladus orientalis,and Pinus thunbergii.The stemflow capacity dropped in the order of 15a Quercus acutissima,50a Quercus acutissima,Pistacia chinensis,Acer mono,Pinus thunbergii 15a Quercus acutissima,50a Quercus acutissima,Pistacia chinensis,Acer mono,Pinus thunbergii,Robinia pseudoacacia,Platycladus orientalis,Robinia pseudoacacia,Platycladus orientalis.In general,critical value of open field rainfall for produced through rainfall in stand of various forest stands was 6.28mm.
