摘要/Abstract

摘要： 研究了阴香（Cinnamomum burmannii）种群的年龄结构及其年龄与胸径的关系,绘制了阴香种群的存活曲线和年龄结构图。结果表明：阴香种群的年龄与胸径呈明显的线性相关,种群幼龄个体较多,中老龄个体较少,年龄结构呈增长型和稳定型两类,存活曲线呈现出Deevey Ⅲ型和Deevey Ⅱ型。生境条件和人为干扰是影响阴香种群年龄结构和动态的重要因素。因此,对于阴香群落要加强保护、减少人为干扰和加强抚育管理。

Abstract: In this paper, age structure, the relationship between the age and the stem diameter of Cinnamomum burmannii populaion were studiedl survival curve and age structure pictures were given.This results showed that on the Karst hills of Guilin, there was a linear relationship between the age and the stem diameter of C. burmannii population. Young-aged individuals were more, while middle-aged and old individuals were less. The age structure was classified into two types, growing and stable, while the survival curve was of types Deevey Ⅲ and Ⅱ. Habitat condition and human disturbance were the main factors affecting the age structure and the dynamics of C. burmannii population, and thus, the protection and fostering of C. burmannii community should be reinforced, meanwhile the human disturbance should be reduced.
