中文摘要：
种群空间分布格局能够反映个体在水平空间上的相互关系。本研究通过对施秉白云岩喀斯特地区的南方红豆杉群落进行研究,用6个聚集度指标分析其空间分布格局。结果表明,南方红豆杉种群年龄结构属于倒壶形,种群属于衰退型,呈下降趋势,没有幼年个体,中、老年个体较多;聚集度指标表明南方红豆杉为集群分布。
英文摘要：
The spatial distribution pattern of populations could reflect the mutual relationship of individuals in horizontal space. In this study, we studied T. chinensis community in Shibing dolomite in Karst area and used 6 ag gregation indexes to analyze its spatial distribution pattem. The results showed that the age structure of population was inverted-pot shaped, as the population was declining with no juvenile but more medium and senile individuals; aggregation index indicated that the distribution pattern of T. chinensis population was spatial cluster distribution.
