摘要
选择桂林七星公园中的阴香种群,采用"径级大小替代年龄大小"的方法,进行阴香种群年龄结构的研究,同时绘制了种群的年龄结构图及存活曲线。结果表明:4个样地中,样地2、样地4的阴香种群的年龄结构呈增长型,存活曲线为DeeveyⅠ型;样地1、样地3的阴香种群的年龄结构呈衰退型,存活曲线为Deevey II型。影响阴香种群年龄结构及其动态的主要因素为人为活动干扰。
Cinnamomum burmannii population age structure in Qixing Park was analyzed by the method of class size substituting for age size. Age structure diagram and survivorship curve were also drawn. The results showed that,C. burmannii population age structure of the sample- 2 and sample- 4 presented a growth trend,the survival curve was Deevey I type. C. burmannii population age structure of the sample- 1and sample- 3 presented a recession trend,the survival curve was Deevey II type. Human activities interference was the main influence factor of C. burmannii population age structure and its dynamic.
