摘要: 采用典型抽样法和生态群落学调查法对黑龙江凉水国家级自然保护区紫椴(Tilia amurensis)红松(Pinus koraiensis)林、蒙古栎(Quercus mongolica)红松林及白桦(Betula platyphylla)次生林的植物群落结构特征和物种多样性进行了研究。结果表明,紫椴红松林有维管束植物31种,隶属21科,25属;蒙古栎红松林有维管束植物32种,隶属25科,28属;白桦次生林有维管束植物31种,隶属20科,28属。白桦次生林乔木层和草本层的物种丰富度S指数显著高于2种阔叶红松林,而其灌木层的物种丰富度S指数最低;3种林型乔木层的Simpson物种多样性指数无显著差异,紫椴红松林的灌木层Simpson指数显著高于其他2种林型,3种林型草本层之间的Simpson指数差异显著;紫椴红松林乔木层的Shannon-Wiener物种多样性指数显著低于其他2种林型,白桦次生林灌木层的Shannon-Wiener指数显著低于2种阔叶红松林,蒙古栎红松林草本层的Shannon-Wiener指数最高;此外,蒙古栎红松林乔木层的Pielou均匀度指数显著高于其他林型,而3种林型灌木层的Pielou指数无显著差异,紫椴红松林草本层的Pielou指数最低。

Abstract: We used typical sampling and community-ecology survey methods to study the plant community structure and species diversity of Amur linden(Tilia amurensis)-Korean pine(Pinus koraiensis) forest, Mongolian oak(Quercus mongolica)-Korean pine forest and Birch(Betula platyphylla) secondary forest in Heilongjiang Liangshui National Nature Reserve. There were 31 vascular plant species in Amur linden-Korean pine forest, belonging to 21 families and 25 genuses. There were 32 vascular plant species in Mongolian oak-Korean pine forest, belonging to 25 families and 28 genuses. There were 31 vascular plant species, belonging to 20 families and 28 genuses in Birch secondary forest. The species richness index S of tree layer and herb layer of Birch secondary forest were significantly higher than two kinds of broadleaved-Korean pine forest, and the shrub layer was lowest. Based on Simpson species diversity index, there was no significant difference between tree layers of three forest types, the shrub layer of Amur linden-Korean pine forest was significantly higher than the other two forest types, and the herb layers of three forest types were totally different. Based on Shannon-Wiener species diversity index, the tree layer of Amur linden-Korean pine forest was significantly lower than the other two forest types, and shrub layer of Birch secondary forest was significantly lower than the other two broadleaved-Korean pine forest, but the herb layer of Mongolian oak-Korean pine forest was highest. Pielou species homogenous index of tree layer of Mongolian oak-Korean pine forest was significantly higher than the other two forest types, there was no significant difference between shrub layers of three forest types, and the herb layer of Amur linden-Korean pine forest was lowest.

Key words: broadleaved-Korean pine forest, birch secondary forest, plant diversity, species diversity
