Distribution characters of Soil Microbial in Wuzhi part of Yellow River Riparian Wetland after artificial restoration

摘要

This article describes the distribution characteristics of soil microbial in different vegetable types in artificial wetland restoration. The results show that quantity of microbial had a significant increase before and after restoration. The value of Polygonum hydropiper sample was largest. The sequence of increase was Polygonum hydropiper,Phragmites communis Trin, Typha angustifolia and bare land; Referring to the change of three types of microorganisms, bacteria enhance 2.16 times largest; Meanwhile fungi go up 1.11 times least. The range of microbial diversity value before restoration is 0.2437-0.7633, and after is 0.1163-0.4069;Bacteria amount had significant correlation with TN.
