摘要
为了解许昌市河流滨岸植物多样性现状,通过Shannon-weiner指数、Pielou指数和频度综合分析许昌市9 条河流12 个断面滨岸植物多样性.结果表明,样地含属 3 种以上的科有 2个,芦苇、牛筋草、酸模、狗尾草、艾的频度较高,在群落中有代表性.河流滨岸植物的Shannon-Wiener指数在0~1.876 波动,Pielou均匀度指数在0~1 波动,植被多样性状况较好.
Abstract
In order to explore the current status of riverbank plant diversity in Xuchang City,the Shannon weiner index,Pielou index,and frequency were used to comprehensively analyze the diversity of riverbank plants in 12 sections of 9 rivers in Xuchang.The results showed that there were 2 families with more than 3 species in the sample plot.Reed,cow sinew,sorrel,setaria and moxa had high frequency and were representative in the community.The Shannon Wiener index of riverbank plants fluctuated between 0 and 1.876,while the Pielou evenness index fluctuated between 0 and 1,indicating good vegetation diversity.
