摘　　要：贵州省紫云县宗地剖面产出早石炭世大塘期至早二叠世栖霞期连续的■类化石序列。研究结果显示:该段地层中共产出■类36属453种(包括14个新种、14个亚种、47个相似种、18个变种以及30个未定种)。依据化石组合特征,可以识别出13个■类化石带,从老至新为Eostaffella-Eostaffellina富集带,Pseudostaffella富集带,Profusulinella deprati延限带,Profusulinella chaohuensis-P.fenghuangshanensis间隔带,Fusulina-Fusulinella富集带,Protriticites ziyunensis　sp.nov.富集带,Triticites hobblensis延限带,Triticites panteleevi富集带,Spha-eroschwagerina subrotunda延限带,Eoparafusulina ovata富集带,Staffella-Pseudoendothyra组合带,Miselli-natermieri富集带,Misellina pamirensis-Misellina ovalis共存延限带。依据各带中的■类属种分布,宗地剖面的■类化石带序列可以很好地与中国华南、北美得克萨斯、日本中部和俄罗斯等地区同期的■类化石序列对比。The Early Carboniferous to Early Permian fusulinid faunal succession from the Zongdi Section in Ziyun county, southern Guizhou, is reported here. Detailed study on this succession shows that there are 453 fusulinid species belonging to 36 genera contained in the Datangian to Chihsian strata of the Zongdi Section, including 14 new species, 14 subspecies, 47 conformis species, 18 varieties and 30 undetermined species. Thirteen fusulinid zones have been recognized according to the changes of components of the fusulinid faunas, and they are, in succeeding order, Eostaffella-Eostaffellina abundance zone, Pseudostaffella abundance zone, Profusulinella deprati range zone, Profusulinella chaohuensis-P, fenghuangshanensis interval zone, Fusulina-Fusulinella abundance zone, Protriticites ziyunensis sp. nov. abundance zone, Triticites hobblensis range zone, Triticites panteleevi abundance zone, Sphaeroschwagerina subrotunda range zone, Eoparafusulina ovata abundance zone, Staffella-Pseudoendoth yra assemblage zone, Misellina termieri abundance zone,Misellina pamirensis - Misellina ovalis concurrent-range zone. These fusulinid faunas of these zones could be well correlated with the contemporary faunas from other areas of South China, Texas of America, Central Japan and Russia.
