江苏盐城原生滨海湿地土壤中的微生物群落功能多样性分析
Function diversity of soil microbial communities in original coastal wetlands,Yancheng,Jiangsu Province
摘要
Abstract
We analyze the functional diversity of soil microbial communities in four seasons and deepness between 0~20 cm and 20~40 cm in 7 representative wetlands locating in Jiangsu Yancheng original coastal wetlands.Results showed that Sparinaalterniflora wetland and Phragmitesaustralis wetland had the highest functional diversity and livingness,Suaeda glauca wetland has the lowest values and bare flat was among the middle.The variances of Shannon-Wiener diversity in different seasons in surface layer is larger than sub-surface layer as a whole,while the difference between the variances of Shannon-Wiener diversity in different seasons in surface layer and sub-surface layer is less in Sparinaalterniflora wetland and Phragmitesaustralis wetland,but larger in Suaedaglauca wetland and bare flat;the functional diversity and structure of soil microbial communities is similar in July and October,but with significant difference in January and April.The characters of soil microbial communities in Sparinaalterniflora wetland and Phragmites australis wetland are similar,which is the usage ability of the whole carbon resource that causes the different structure of soil microbial communities in different wetlands,seasons and deepness;the changes in different seasons is the most important reason that impacts the structure of soil microbial communities than wetland types and deepness.关键词
