The Indication Of Soil Microorganism To Wetland Restoration In Three River Source Area

Post-assessment of wetland restoration projects offers insight into project efficiency, effectiveness and sustainability. In order to evaluate the wetland restoration in three river source area, Qinghai Province, 16SrRNA high-throughput sequencing, OTU analysis, Alpha diversity analysis, etc., were used to analyze the soil microorganisms in the three restoration measures. Then, the species distribution and species richness cluster information were obtained. Compared with the wetland without any restoration measures, the results showed that the soil health index in three plots was higher or lower, which was specifically reflected in: replanting plot > rodent control plot > enclosure plot. Finally, the health status of alpine meadow wetland was comprehensively analyzed. The results in this work can offer reference for the restoration and protection of meadow wetland in Qinghai-Tibet Plateau.
