摘要 于福建省长汀县四都楼子坝国有林场选择3种利用方式的林地设置标准样地,测定其土壤中全铝及交换性铝的含量.结果表明:杉木连栽(AA)、杉木—马尾松—杉木(ABA)轮作及杉木—马尾松轮作(AB)等3种利用方式林地的不同土层土壤全铝含量差异略有不同,除了上坡20~40 cm土层及中坡0~ 20 cm和20~ 40 cm土层AB与AA、ABA的土壤全铝含量存在显著差异外,其余各种林地利用方式和不同土层的土壤全铝含量都没有显著差异;与全铝含量相比,土壤交换性铝含量的变化规律约有不同,除了上坡0~20 cm土层的AB与AB、ABA,中坡0 ~ 20 cm土层的ABA与AA、AB,下坡20~40 cm和40 ~ 60 cm的ABA与AA、AB土层的土壤交换性铝含量差异显著外,其余无显著差异. Total aluminum and exchangeable aluminum content in soil of 3 kind utilization patterns in Fujian Sidu Louziba national forest farm were explored. Results showed that continuous Chinese fir planting, fir-pine-fir rotation and fir-pine rotation did not showed significant difference on total aluminum content, except for upper slope layers of 20 ~ 40 cm and middle slope layers of 0 - 20 cm and 20 - 40 cm between AB and AA, ABA. Rule of exchangeable aluminum was not similar to total aluminum. There were not significant differences on exchangeable aluminum content, except for 0 -20 cm layers in upper slope between AB and AB, ABA, and 0 - 20 cm layers in middle slope between ABA and AA, AB, and 20 - 40 cm and 40 - 60 cm layers in lower slope between ABA and AA, AB.
