摘　　要：通过对采自广东省大鹏半岛的土壤混合样品进行纤毛虫定性和相对定量的分析 ,研究了大鹏半岛土壤纤毛虫的群落特点 .其群落由 42种纤毛虫组成 ,其中包括我国的新记录种 4个 ;主要种类有蝶形康纤虫(Cohnilembusvexillarius)、背沟肾形虫 (Colpodahenneguyi)、斯氏肾形虫 (C .steinii)、苔藓织毛虫 (Histriculusmuscorum )、近亲殖口虫 (Gonostomumaffine)、旋转单镰虫 (Drepanomonasrevolata)、有肋薄咽虫 (Leptopharynxcostatus)及高山长颈虫 (Dileptusalpinus)等 .通过对该地区土壤样品中纤毛虫的培养 ,发现该群落的优势种从培养初期的近亲殖口虫和苔藓织毛虫演变为蝶形康纤虫 ,进而演变为肾形虫 .比较了大鹏半岛土壤纤毛虫群落与其它地区土壤纤毛虫群落间的差异 ,并分析了引起差异的可能因素 .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.
