Soil nematodes are an import indicator of soil ecosystem. Exploring the characteristics of the spatial distribution pattern of soil nematode trophic function groups in alpine meadows is helpful to reveal the response to the change of alpine meadow ecological factors. In the middle of July 2019, the spatial characteristics of soil nematode trophic function groups in 5.0 m × 4.0 m scale soil layers (0﹣20 cm) were studied by the grid method (1.0 m × 0.5 m). Using modified wet funnel method, a total of 1 830 soil nematodes were obtained, belonging to 49 genera, with an average of 63.2 soils nematodes per 50 g of dry soil, Plectus and Acrobeloides were the dominant groups; soil nematodes were mainly bacterivorous nematodes and plant parastic nematodes. The variable coefficient of soil nematode trophic function groups was between 64.4%﹣100.6% (n = 38 soil samples), and had a strong variability. There was a significant correlation between the spatial distribution of fungivorous and bacterivorous nematodes (t = 0.415, P < 0.001), fungivorous and plant parastic nematodes (t = 0.437, P < 0.001). Geostatistical analysis showed that the spatial correlation range of the soil nematode trophic function group had significant difference. The effective variable range was between 0.50 to 27.07 m, and 67.26% to 99.79% of the variation was related to the spatial autocorrelation process. The distribution pattern of bacterivorous soil nematodes was a relatively uniform patch mosaic structure, and the patches are small; non-bacterivorous soil nematodes were patch-connected or patch-mosaic, with large patches and obvious transitions between patches, indicating that that the small-scale obvious patch structure of soil nematodes may be a common distribution pattern in alpine meadow after being disturbed, and affected by many factors.
