摘要通过采用丰富度指数(Margale、Menhinick等)、均匀度指数(Pielou、Heip和Alatalo等)和多样性指数(Gini、Shanon_Wiener和Simpson等)等3种测度方法对帽儿山地区天然次生林群落植物多样性特征进行了研究。结果表明:帽儿山地区天然次生林群落植物的最重要植物为胡桃楸;Z602样地的各种多样性指标均高于M701样地,可见Z602样地的多样性更为优越。

AbstractThe characteristics of species diversity of communities in natural secondary forest in Maoershan Region were studied.Three measurement methods:richness index (Margale,menhinick richness index),evenness index (Pielou,Heip’s & Alatalo evenness index),diversity index (Gini,Shanon-Wiener and Simpson diversity index) were used to study the characters of the diversity of plant species in the community in natural secondary forest of Maoershan region. Result shows that Juglans mandshurica is the most important plant in natural secondary forest of Maoershan region; each diversity index of Z602 plot are higher than that of M701 plot,it is clear that the diversity of Z602 plot are more superior.

对帽儿山地区天然次生林物种多样性进行初步的研究和分析,探讨帽儿山地区森林植物物种组成特征,并通过对群落植物物种的丰富度、均匀度和多样性的特征分析来进一步了解帽儿山地区天然次生林群落的发展水平,可以为后人深入研究和帽儿山地区生态环境的保护提供基础数据。更好地保护黑龙江地区这一受人为影响较小的天然次生林群落。
