热带森林乔木种群分布格局及其研究方法的比较

Distribution pattern of tree populations in tropical forest and comparison of its study methods.

应用样地个体数为基础的方差／均值比率、Ｍｏｒｉｓｉｔａ分散指标，以及以个体距离为基础的最近邻体法、复合个体距离分析法对海南岛吊罗山山地雨林８个主要种群分布格局进行了比较研究．结果表明，８个种群为聚集或随机分布，４种测定方法中以复合个体距离分析法较好．

By means of individual in plot based variance/mean ratio and Morisita's dispersion index, and individual distance based modified nearest neighbor method and combined count distance analysis, the distribution patterns of eight major species in mountainous tropical rain forest in Diaolou Mountain of Hainan were investigated. The results show that the distributions of all eight species are clumped or random, and that among the four methods, the combined count distance analysis is the best.
