摘要
运用邻体干扰模型及其野外工作方法 ,初步研究了缙云山亚热带次生常绿阔叶林优势种马尾松 (Pinusmas soniana)、大头茶 (Gordoniaacumenata)和白毛新木姜子 (Neoliteaauratavar .glauca) 3个种群间的竞争效应与竞争反应 .结果表明 :(1)种内竞争效应排序为马尾松 >大头茶 >白毛新木姜子 ;(2 )种间竞争效应排序为白毛新木姜子 >马尾松 >大头茶 ;(3)种间竞争反应排序为大头茶 >马尾松 >白毛新木姜子 ;(4)白毛新木姜子与大头茶之间的竞争强度最大 ,达到 1.0 5 ;大头茶与马尾松之间的竞争强度最小 ,仅为 0 .32 .表 3参
The neighbourhood interference among three dominant tree species (Neolitsea aurata var. glauca, Gordonia acumenata, Pinus massoniana) in the subtropic secondary evergreen broadleaved forest in Jinyun Montain was studied based on the competitive effect and competitive response models of neighbourhood interference among the dividuals of interspecies. The result shows that: (1) The order of intraspecific competitive effect is: Pinus massoniana>Gordonia acumenata>Neolitsea aurata var. glauca; (2) That of interspecific competitive effect is: Neolitsea aurate var. glauca>Gordonia acumenata>Pinus massoniana; (3) That of interspecific competitive response is: Gordonia acumenata>Pinus massoniana>Neolitsea aurate var. glauca; (4) The competitive intensity between Gordonia acumenata and Neolitsea aurata var. glauca reaches 1. 05, which is the maximum. While the competitive intensity between Gordonia acumenata and Pinus massoniana reaches 0. 32, which is the minimum. Tab 3, Ref 8
