Abstract:
      To understand the current status of biodiversity restoration in the riparian zone of the Liao River reserve in China and to promote the healthy management of this ecosystem, the plant and microbial diversity of 23 sampling sites in the mainstream were determined through field investigations and high-throughput sequencing of soil microorganisms. The results showed that the average Shannon-Weiner diversity index of the 23 sampling points was 1.227, with an average vegetation cover of 74.19%. The Shannon-Weiner diversity index of soil microorganisms in the riparian zone was 9.55, and there were 11 phyla, 32 classes, and 40 genera of bacteria whose dominance was more than 1%. Disturbance from human activities, grazing conditions, and land-use types were the key factors affecting the plant and microbial diversity in the riparian zone. At present, the recovery of riparian biodiversity in the Liao River reserve is in a good state, but increases in human activities negatively affect biodiversity restoration. Therefore, the study recommend the reduction of human activities and grazing in the restricted area as much as possible, so as to accelerate the restoration of plant and soil microbial diversity in the riparian zone of the Liao River reserve.
