摘  要:
采用空间序列代替时间序列的方法,对白桂木5个种群进行统计分析,编制种群的特定时间生命表,应用聚集强度指数进行种群分布格局分析。结果表明:白桂木种群结构呈纺锤形,幼苗严重不足,种群有衰退趋势;存活曲线基本接近DeeveyⅡ型;种群分布格局整体呈聚集分布。

摘  要:
With the method of spatial series substituting for time series,five populations of Artocarpus hypargyreus were analyzed,its time-specific life table was analyzed,its distribution pattern was discussed by assembling intensity index.The results showed that the population structure of Artocarpus hypargyreus was a spindle type.The age structure of the population of Artocarpus hypargyreus was declining due to lack of seedlings;the survival curve of Artocarpus hypargyreus population belonged to DeeveyⅡ type;the overall population distribution followed a assembled.
