摘要
分析红豆树(Ormosia hosiei)百年以上老林分的11个乔木层树种的相对优势度、物种多样性、均匀度、生态位宽度、生态位重叠度等指标。红豆树在该生态环境中比其它树种的适应性都好。红豆树种群稳定性较好,榕冬青次之,其它树种尚处群落发育初期,演替趋势不稳定。
The relative dominant degrees, species diversity, even degrees, niche width, niche overlapping degrees, and other indicators were analyzed by the arbor trees of 11 stories in the hundred-year-old virgin forest of Ormosia hosiei Hemsl. et Wils.. The population adaptability of Ormosia hosiei in that ecological environment was better than other species. The population stability of Ormosia hosiei was the best, I. ficoidea the next, and the other species still in the initial developmental stage of community. The community succession trend was instable.
