摘要
对缙云山草珊瑚种群年龄结构进行分析,并运用扩散系数的t检验、Morisita指数的F检验来研究缙云山草珊瑚种群的空间分布格局类型,同时采用K,GI,m*,PAI以及CA来研究其聚集强度.结果表明,缙云山草珊瑚种群为间歇型的种群结构,不同地段的草珊瑚种群空间分布格局有所差异,表现为随机分布和集群分布,但总体上表现为集群分布且聚集强度较高.
The population age structure of Sarcandra glabra in Mt. Jinyun was analyzed. Its spatial distribution pattern was studied by applying t test of Dispersal index and F test of Morisita＇s index. Its assemble intensity was analyzed through the aggregate indices of K, GI, m^＊ , PAI and CA. The results indicated that the population structure of S. glabra was of the intermittent type, and its spatial distribution patterns were random and clump in different areas. In general, S. glabra exhibited a clumped distribution pattern with a relatively strong assemble intensity.
