| 摘 要： | 根据2010年7月对河北木兰围场自然保护区0.4 hm2油松人工林的样地调查结果,采用点格局分析法,对油松种群各龄级在不同尺度下的空间分布格局进行分析。结果表明,试验地内油松林处于青壮龄期时,空间分布呈现显著的聚集分布,种内竞争较为激烈。

| Abstract: | Based on the inventory results of 0.4 hm2 sample plot of P.tabulaeformis plantation in Mulanweichang of Hebei province in July of 2010,the method of point pattern analysis was employed to study the spatial distribution patterns of different age-classes for P.tabulaeformis community under different scales.The results showed that: the P.tabulaeformis plantation was in vigorous growth period,the spatial distribution patterns presented distinct cluster mode,and the interspecific competition is relatively fierce... |
