Promotion of Soil Microbial Community Restoration in the Mu Us Desert (China) by Aerial Seeding

Soil microbial communities link soil and plants play a key role in connecting above-ground below-ground terrestrial ecosystems. Currently, how artificial revegetation promotes the restoration of community diversity degraded ecosystems attracts extensive attention. In this study, samples were collected from long-term artificially restored mobile sandy lands (aerial seeding sample plots) 1983 to 2015 Mu Us Desert. The second-generation high-throughput sequencing technology was adopted identify microorganisms analyze changes their structure diversity. relationships between nutrients explored by Pearson correlation analysis canonical correspondence analysis. addition, subsurface area evaluated. results are as follows: (1) alpha increased significantly with period, composition plots different years varied significantly. (2) nutrient indexes, such total carbon, nitrogen nitrate nitrogen, period positively correlated fungal bacterial (3) Key phyla contributed cycling It can be concluded that afforestation aerial facilitates change increases This paper provides basis for future measures policies restoring
