| 摘 要： | 研究了贵州纳雍光叶珙桐群落11个主要优势种群生态位宽度及重叠,结果表明,在该群落中以西南红山茶、猫儿屎、光叶珙桐的生态位宽度较大;群落中主要种群间生态位重叠的发生比较普遍,但是重叠的程度不是很高,说明物种间存在竞争,群落尚未达到稳定的顶级群落阶段,尚处于演替的进程中。

| Abstract: | In this paper, the population niche breadth and overlap of 11 major advantage species in Nayong was researched. The resuits showed that the niches breadth of Camellia Pitardii, Caisnea insignis and Davidia involucrate were largest. Niche overlap was relatively common but it was not significant. There were competitions between species. Communities had not yet reached a stable climax community stage and it was still in the process of succession. |
