Abstract:

Saline soil in arid regions is important land resources in China, and their improvement and utilization are an important element in promoting the green and sustainable development of China, which is related to national food security and ecological safety. Microorganisms, as an important part of soil ecosystem, play an important role in the improvement and management of saline soils and improving the salt tolerance of plants. Intensive study on soil microbial diversity, community structure and functional characteristics in arid saline soils and the related factors can provide important microbial references for the restoration and ecological reconstruction of saline soil in arid regions. The paper organized the overview of saline soil in arid regions, analyzed the characteristics of microbial diversity, community structure and ecological function in saline soils, elaborated the related factors of saline environment on soil microbial communities, and put forward the problems in microbial research in arid saline soil and the future development direction. This review can provide references for the development and utilization of saline soil and microbial resources management in arid regions in China.

Key words: arid region, salinization, soil microorganism, community structure, functional genes
