采用“空间替代时间”和扩散系数（C）等6种聚集度指数研究福建省长汀县石峰寨野生桂花种群大小结构及空间分布格局，并探讨桂花在不同生长阶段的空间格局变化过程。结果表明，桂花种群大小级结构随不同年龄阶段增长数量呈相对减少的趋势，种群结构较年轻且平稳，从幼树向中树过渡阶段存在着一个过滤筛。桂花种群在不同样地的分布格局具一定差异性，这是由于限制因子与种群适应对策综合作用的结果。不同生长阶段种群的分布格局基本上由集群型转变为随机型，聚集度不断减小，幼苗和幼树阶段的桂花种群为集群分布，到成树阶段则转变为随机分布。

By applying the method of "space replacing time" and contiguous grid quadrat and other 5 kinds of aggregation index, the size structure and spatial distribution patterns of Osmanthus fragrans wild populations in Sifengzai area of Changting county in Fujian province were studied, then the change process of spatial pattern of O. fragrans in different growth stages was analyzed. The results showed that O. fragrans wild populations had a trend that the number of population decreased with the development of growth phase, have a young and stable population structure, in addition, there was a peak from the phase of saplings to mature trees. The distribution pattern of O. fragrans populations in different samples has certain differences, due to the comprehensive effects of limiting factors and population adaptive strategies. The spatial distribution patterns of O. fragrans were change from cluster types to random types, intensity degree decreased with the development of growth phase, the distribution patterns of seedling and samplings were cluster distribution while mature trees were random distribution.
