豫西山区森林群落邻体竞争效应的初步研究

运用邻体干扰指数模型，分析了豫西山区森林群落中主要种群的种内种间竞争强度，以及种群和个体在群落中的竞争干扰状态．结果表明，幼龄林群落中的种内、种间竞争指数因生境条件不同有所差异；中龄林群落基本稳定，其阔叶类种群的平均竞争指数小于针叶类种群的平均竞争指数，说明针叶类种群处于被压状态而阔叶类种群处于竞争状态，自然情况下的群落演替过程中阔叶类种群将占优势．

A study on adjacent competition effect of forestry community of mountainous area in western Henan Province

Using the adjacent interference model, this paper studied the inner and intra species competition intensity of main species in mountain forestry community of western Henan Province and the competition interference state of species and individual in the community. The results showed that the inner and intra species competition indices in the younger stand varied according to biotope condition; while the stand reached middle age when community was in a stable state, the average competition index of broad leaf species was smaller than that of needle leaf species, which indicated that the needle leaf species was in a oppressed state but the broad leaf species was in a competition state, and that the broad leaf species will have priority in the natural community success process.
