Abstract: With the qualitative and quantitative analysis, the community characteristics of soil ciliated protozoan sample from Dapeng Peninsula,Guangdong province was studied.The comunity consisted of 42 species of ciliates, including 4 new records in China.The major species were Cohnilembus vexillarius,Colpoda henneguy,Clopoda steinii,Histriculus muscorum,Gonostomum affine,Drepanomonas revolata,Leptopharynx costatus and Dileptus alpinus. Culturing the ciliated protozoan in laboratory showed that the species succession of domimant speies during the culture was from Gonostomum affine and Histriculus muscorum n the early stage to Cohnilembus vexillaria, and then to Colpoda spp.The difference of soil cliated communities between in Dapeng Peninsula and other regions was compared,and the possible factors affecting the difference were analyzed.
