摘  要:
为揭示楠杆保护区境内楠木种群结构与分布格局特征,开展保护区境内楠木资源专项调查,采用"空间替代时间"的方法分析径级结构,编制生命表,并进行种群生存力分析.种群动态结构指数显示,0~<5、5~<15 cm这2个龄级之间保护区楠木种群为增长型;至15 cm以后的龄级段间,楠木种群表现为衰退型.

摘  要:
In order to reveal the characteristics of population structure and distribution pattern of Phoebe zhennan in the reserve,the special investigation of P.zhennan resources in the nature reserve was carried out.The diameter class structure was analyzed by the method of "Space Replaces Time",the life table was compiled,and the population viability was analyzed.The population dynamic structure showed that the population of Phoebe zhennan in reserve was growing at 0~<5,5~<15 cm age class.At the age range >15 cm,the population of P.zhennan showed a declining pattern.
