| 摘 要： | 应用植物种群生态学的研究方法,对浙江凤阳山自然保护区福建柏的种群结构和分布格局进行了研究,探讨了其动态过程及机制。结果表明:在所设的样地中,福建柏种群大小级分布图的形状基本相似,种群的年龄结构为稳定型;其分布格局主要以随机分布为主,也有一定比例的集群分布,但集群强度有差异,且幼苗和幼树的集群强度明显大于中树,树种呈扩散趋势。 |

| Abstract: | Using the methods of plant population ecology,the structure and distribution pattern of Fokienia hodginsii population in Fengyang Mountain Nature Reserve,the dynamic process and mechanism were studied.The results showed that the distribution diagram shapes of different size were basically similar in different quadrats.The age structure was stable.The distribution patterns of Fokienia hodginsii population were mostly poisson distributed.There were some clump distributed in some quadrats,but they were different in terms of intensity.The intensity of seeding and young trees was bigger than that of medium size trees and the population tents to be diffusion. |
| Keywords: | Fokienia hodginsii population structure distribution pattern Fengyang Mountain Nature Reserve |
