Abstract

To obtain a better understanding of the responses of soil ciliate communities to ecological restoration, a quarterly survey of the soil ciliate community and seasonal dynamics across five sampling sites of artificial spruce forest was undertaken. A contrast sampling site of wild grassland was used and live observation ciliates and the three level ten-fold dilution method was used in Huajialing, Dingxi, Gansu. A total of 127 species were identified, belonging to three classes, nine orders, 34 families and 50 genera. Results show that the species distribution had obvious differences across the sampling sites, the community structure of soil tended to be complicated and species comparability decreased gradually with the number of restoration years, and abundance, species richness and species diversity index showed an upward trend. The dominant groups of soil ciliates changed during ecological restoration. Colpodida was the dominant group in sampling site I and site II, whereas Hypotrichida was the dominant group in the late recovery sampling sites. This study shows that the dynamics of the soil ciliate community better respond to soil condition changes in the ecological restoration process. Although the soil ciliate community can be used to evaluate the effect of ecological restoration of terrestrial ecosystems, plenty of further systematic research to establish an effective and feasible evaluation index system is required.
