摘要
2009年6月、7月和2011年7月在河南济源南山森林公园,采取样方调查法,对刺槐森林群落进行了物种多样性调查。结果表明:Margalef(R)、Shannon-Wiener(H)和Pielou(J)指数均为草本层>灌木层>乔木层,Simpson(D)为乔木层>灌木层>草本层。不同林龄群落物种多样性为30年>20年>40年>10年。不同坡向分析表明:刺槐群落的乔木层和灌木层物种多样性在南坡较高,草本层多样性在西坡较高。因此,刺槐群落适宜在南坡和西坡营造,对30年以上的成熟刺槐林应及时更新,保持物种多样性。
The species diversity of Robinia pseudoacacia community was studied by sampling method in Nanshan Forest Park in Jiyuan City of Henan Province in June and July, 2009, and July, 2011. The results showed that the Margalef index（R）, Shannon-Wiener index （H） and Pielou index （J） were herb layershrub layer〉tree layer, Simpson index （D） was tree layer〉shrub layer〉herb layer. The species diversity of Robinia pseudoacacia with different plantation age was 30 years〉20 years〉40 years〉10 years. On different slope aspects, the species diversity indexes were higher on the southern for the tree and shrub layer. The herb layer species diversity indexes were higher on the western. Therefore, from the slope aspects perspective, the southern and western should be more suitable for Robinia pseudoacacia community, and from the stand age perspective, the positive human disturbance and regener- ation should be taken to the mature Robinia pseudoacacia forest to keep the species diversity.
