摘要
应用群落生态学方法探讨加拿大一枝黄花对南京和苏州地区植物的影响风险。测定结果显示:加拿大一枝黄花生长地区植物物种丰富度(S)、总数量(N)、均匀度(J)、群落多样性(H)、综合优势比(SDR)均低于没有一枝黄花生长地区;加拿大一枝黄花生长地区的植物群落稳定性比没有加拿大一枝黄花生长地区差,表明加拿大一枝黄花存在较大的生态风险性。
In order to evaluate the ecological safety and risk of Solidago canadensis, the composition and diversity of the plant community in the cite of the growth of Solidago canadensis were studied by means of the quantitative analysis method in Nanjing and Suzhou district. The results showed that significant difference in total species richness, individual no. , evenness and community diversity in the cite of growth of Solidago canadensis were more lower than those in the cite of no growth of Solidago canadensis. It is clear that the stability of plant community adherence to Solidago canadensis is different significantly than that of no Solidago canadensis and its ecology risk increased by Solidago canadensis is obvious.
