作者：董元火 许国权 曾长立 廖新安 张洪干 张文才 夏恒建 王圣军 全德文 郭双喜来源：《安徽农业科学》2021年第01期 摘要采用α-多样性指数分析了湖北蕲春清水河野生蕲艾落物种多样性。结果表明：该蕲艾种面积为110～120 m2，植株数300～400株，盖度仅为10%左右。主要有16科24 中国疫情即将放开属28种与蕲艾相伴生。蕲春清水河野生蕲艾落的丛名为构树+一年蓬。α-多样性指数分析显示清水河蕲艾落丰富度指数（R）、Simpson指数（D）、Shannon-Wiener多样性指数（H′）和Pielou 均匀度指数（J）分别为28、0.817、3.397和1.020。人为干扰是影响该野生蕲艾种恢复更新的重要原因。

AbstractThe species diversities of wild Artemisia argyi community at Qichun in Hubei were surveyed by using α-diversity index. The main results were as follows： the population area of A. argyi was 110-120 m2， coverage was 10%. The population sizes were about 300-400 individuals. It was found that there were 28 plant species belonging to 16 families and 24 genera in the community. The vegetation was called as Broussonetia papyrifera + Erigeron annuus Ass. α-diversity index analysis indicated that
Richness index （R）， Simpson index （D）， Shannon-Wiener diversity index（H′） and Evenness index （J） were 28， 0.817， 3.397 and 1.020， respectively. Human disturbance might be an important factor that affecting the wild populations of restoration and regeneration.
