摘　　要：采用α-多样性指数分析了湖北蕲春清水河野生蕲艾群落物种多样性。结果表明:该蕲艾种群面积为110~120 m 2,植株数300~400株,盖度仅为10%左右。主要有16科24属28种与蕲艾相伴生。蕲春清水河野生蕲艾群落的群丛名为构树+一年蓬。α-多样性指数分析显示清水河蕲艾群落丰富度指数(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群恢复更新的重要原因。The species diversities of wild Artemisia argyi community at Qichun in Hubei were surveyed by usingα-diversity index.The main results were as follows:the population area of A.argyi was 110-120 m 2,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.
