污染土壤的微生物多样性研究

MICROBIAL DIVERSITY IN POLLUTED SOILS: AN OVERVIEW

摘要:

土壤微生物多样性是土壤微生物生态学的重要研究内容,目前已成为国际上生态学发展的崭新方向之一。土壤微生物多样性包括微生物群落功能多样性、结构多样性及分子遗传多样性,是指示土壤生态系统稳定性及其功能的重要传感器。本文基于分离培养以及生物标志分子方法,从不同生态层次上认识微生物多样性,较全面、系统地综合评述国内外污染土壤环境的微生物群落功能、结构及分子遗传多样性的研究进展,并针对新形势下土壤污染所面临的新问题,探讨了近期土壤微生物生态学过程研究的重要手段与科学问题。

Abstract:

Soil microbial diversity is an important content of soil microbial ecology,which is a new frontal field in ecology.Soil microbial diversity encompasses functional,structural and molecular genetic diversities of microbial community,and is a key indicator of stability and functions of soil ecosystems.This paper reviews current development in researches of the field of microbial diversity in polluted soils at home and abroad based on the methods of isolating culture and biomarkers,and the knowledge of microbial diversity from the angles of different ecological levels,and explores advanced approaches,new ideas and issues in the research on soil microbial ecological processes aiming at new problems in soil pollution the world is faced with.
