摘要:
 以典型取样的方法，对罕山自然保护区分布的山杨、白桦、黑桦及蒙椴4种不同群落的林下草本植物进行调查，并运用丰富度指数和多样性指数分析不同天然次生林林下草本植物的物种多样性。结果表明，在罕山自然保护区4种典型天然次生林林下，草本植物共有124 种，隶属35科91属；以菊科（Compositae）、禾本科（Poaceae）和豆科（Leguminosae）为优势科；白桦（Betula platyphylla）群落林下草本的物种丰富度指数、Simpson多样性指数和Shannon-Wiener多样性指数最高，不同次生林林下草本植物Pielou均匀度指数均无显著差异；相关分析和逐步回归分析表明，海拔是影响草本植物物种多样性的主要地形因子。
Abstract:
 A typical sampling method was used to investigate the understory herbaceous plants in 4 different communities of Populus davidiana,Betula platyphylla,B.dahurica and Tilia amurensis distributed in Hanshan Nature Reserve,and species diversity of understory herbs in different natural secondary forests was analyzed through the species richness and diversity indices.The results showed that there existed 124 herb species belonging to 35 families and 91 genera.Compositae,Poaceae and Leguminosae were the dominant families.The species richness,Simpson diversity index and Shannon-Wiener diversity index in B.platyphylla community were the highest among 4 communities.There was no significant difference in Pielou evenness between herbs.Correlation analysis and stepwise regression indicated that altitude was the main topographic factor that affected species diversity of herbaceous plants.
