- Association Plant diversity and nematode diversity were significantly positively correlated.
- Association Cleistogenes songorica was significantly positively correlated with the herbivorous nematode genus Paratylenchus.
- Association Stipa breviflora was significantly positively correlated with the herbivorous nematode genus Paratylenchus.
- Association Convolvulus ammannii was significantly positively correlated with the nematode genus Acrobeloides.
- Recommendation Grazing intensity should be kept below heavy grazing (light or moderate grazing) as the most appropriate grassland management strategy.
