摘要
研究浙江省凤阳山猴头杜鹃(Rhododendron simiarum)种群的大小级、存活曲线和分布格局,结果表明:不同样地猴头杜鹃的年龄结构不同,有稳定型或增长型、稳定型趋向衰退型以及衰退型等,总体上多数样地猴头杜鹃种群幼苗库数量较为丰富,种群年龄结构为稳定型,猴头杜鹃种群在群落中能得到稳定的发展。猴头杜鹃种群的分布格局呈集群型,这是由物种本身生物学特性和环境条件的综合影响所决定的。
The size-class, survivorship curve and distribution pattern of Rhododendron simiarum Population in Fengyang National Natural Reservation wiere studied and the popalation structure and distribution pattern of R. simiarum were discussed. The results showed that different population had different age structure, there were. stable or increasing type., stable but tend to declining type, declining type in different plots. In general, the seedling pool of R. simiarum population in mnst plots were abundant and the age structure was stable, so that R. simiarum population can stably expand in the community. The distribution pattern of R. simiarum population was contagious distribution. It might be determined by its biological characteristics and the integrated environmental influence.
