摘  要：
以大兴安岭南段阔叶次生林为研究对象,在典型性山杨纯林、黑桦纯林、白桦+山杨混交林、白桦纯林和黑桦+白桦混交林等5个林型内,设置1 m×1 m草本植物样方56块。通过野外调查取样,选取Shannon-Wiener多样性指数、Simpson多样性指数、Pielou均匀度指数和Margalef丰富度指数研究了不同林型的阔叶次生林下草本植物的多样性。结果表明:山杨纯林的Shannon-Wiener指数、Simpson指数最高,分别为1.94和0.84。黑桦纯林的Margalef丰富度指数最高,白桦纯林的最低。随着林型的变化,各指数也相应地发生变化。

摘  要：
Taking the secondary broad-leaved forest in southern the Greater Xing'an Mountains as the research object,about 56 subplots of herbaceous plant at 1 m × 1 m have been set in five forest types,such as typical pure forest of Populus davidiana,pure forest of Betula davurica,mixed forest of Betula platyphylla and Populus davidiana,pure forest of Betula platyphylla,and mixed forest of Betula davurica and Betula platyphylla. Through the field investigation and sampling,Shannon-Wiener,Simpson,Pielou and Margalef indexes have been chosen to study the diversity of herbaceous plants in secondary broad-leaved forest with different forest types. The results show that Shannon-Wiener and Simpson indexes of pure forest of Populus davidiana are 1. 94 and 0. 84 separately. The Margafel index of pure forest of Betula davurica is the highest,with the lowest one in pure forest of Betula platyphylla. The indexes have changed with different forest types,respectively.
