A Review of Impacts of Agricultural Non-point Source Pollution on Microbial Community in Riparian Zone

In recent years, continuous input of exogenous pollutants has changed the original environment of riparian zone, impacting on soil biological community and the stability of ecosystem at the riparian zone. Therefore, it is necessary to study these impacts for environmental protection and providing scientific basis for environmental decision-makers. In this paper, the author took the microbial community of riparian zone as an example and reviewed the relevant literatures at home and abroad published latest years. The impacts of exogenous contamination on microbial community succession in riparian zone were been discussed, and microbial species, microbial biomass and community information were been revealed for understanding the impact of continuous input of exogenous pollutants on micro-ecosystem structure and function and the degree and finding out the leading pollutants in riparian zone. The paper has a great significance to the development of microbial resources and protection of riparian zone.
