Abstract

Abstract: The desert ecosystem accounts for a third of the earth's land area, and is a vital part of the biogeochemical cycle. Because of the bad environmental condition in the desert including extreme drought, lack of vegetation, strong UV radiation, deserts used to be considered lifeless, however there are a lot of microbial resources in this harsh environment especially in the desert soil which enriched with a large number of microbes. These microorganisms involve in the whole earth biochemical circulation of desert ecosystem, adjust the important ecological processes and play an important role in the restoration and stability of the desert ecosystem, its research is of ecological significance. With the development of molecular biological technique, molecular biological technique are revealed. In this paper, the structure characteristics, functionality of desert soil microbial community and the relationships between microbial community, microorganism and plant, microorganism and environment are reviewed. Aim to further understand the desert soil microorganism and to summarize the deficiency of ecological understanding of desert microorganism, provide reference for the ecological research direction of desert microorganism.

Key words: desert, soil microorganisms, microbial diversity, microbial ecology, community structure
