| 摘 要： | 通过野外实地调查与相对干扰度计算,采用物种多样性指数及方差分析、相关分析等方法,对长白山北坡原始林(阔叶红松林)与2种次生林(杂木林与桦木林)的植物物种多样性进行了比较研究,并对影响物种多样性的可能因素进行了系统分析.结果表明:原始林共记录植物物种91种,分别隶属于46科72属;杂木林共记录植物物种128种,分别隶属于53科92属;桦木林共记录植物物种108种,分别隶属于52科87属.仅从Shannon-wiener多样性指数看,桦木林的乔木层、草本层和总体多样性均最小,而灌木层多样性最大;原始林在乔木层多样性小于杂木林,但是在灌木层、草本层和总体多样性均大于杂木林.原始林与次生林草本层的多样性较高,均大于相应的乔木层和灌木层.以原始林为参照,较大的干扰强度使乔木层多样性降低,而较小的干扰强度不仅不会降低乔木层多样性,反而可以增加其多样性;灌木、草本层的多样性受干扰的变化与乔木层相反.

| Abstract: | A study was conducted to compare plant species diversity between primeval forest(broadleaved Korean pine forest) and secondary forests(mixed forest and birch forest) on the northern slope of Changbai Mountain based on the field investigation and calculation of relative disturbance intensity.Factors that might influence species diversity were systematically analyzed.Results showed that 91 plant species belonging to 46 families and 72 genera in total were found in the primeval forest.There were 128 plant spec... |
