摘要
对大明山森林群落的频度进行了分析。结果表明 ,在进行多个样地归并的情况下 ,南亚热带山地常绿阔叶林种的频度分布遵循 A>B>C>D>E的规律 ;在无样地归并时 ,种的频度分布一般符合 Raunkiaer的频度定律。样方数目和大小对种的频度分布有一定的影响 ,随着样方面积的减小和样方数目的增加 ,群落中 A级种的数量增大 ,而
The frequency of forest communities in Daming Mountain has been analysed.The results show that the frequency distribution of species of the mountainous evergreen broad- leaved forest in south tropical zone follows the law of A>B>C>D>E in the case of combination of different plots,but it is up to Ruankianer's law without combination.The numbers of A class species in the communities increase and E class species decrease with increasing of plot number and decreasing of plot area.
