摘　　要：在江西武宁的二叠系栖霞组、茅口组和龙潭组下部获得?类化石8属30种,并对其中10个属种进行系统描述。对获得的?类化石自下而上建立六个?带,分别是Schwagerina anhuiensis-Schwagerina chihsiaensis带、Schwagerina chihsianesis regularis带、Chusenella conicocylindrica带、Chusenella douvillei带、Chusenella ishanensis带和Pseudodoliolina pseudolepida带。通过与南京栖霞山,贵州盘县火铺镇等地的?类化石带对比,本研究区的栖霞组上部、茅口组和龙潭组中下部的地质时代分别为罗德期、沃德期和卡匹敦期。A total of 8 genera and 30 species of the fusulinid fossils are found in the Permian Qixia Formation,Maokou Formation and the lower part of the Longtan Formation in Wuning,Jiangxi,ten species of which are systematically described.Six fusulinid zones were recognized.They are,in ascending order,the Schwagerina anhuiensis Schwagerina chihsiaensis Zone,the Schwagerina chihsiaensis regularis Zone, the Chusenella conicocylindrica Zone, the Chusenella douvillei Zone, the Chusenella ishanensis Zone and the Pseudodoliolina pseudolepida Zone. By comparison with the fusulinid zones in Qixiashan of Nanjing and Huopu Town, Panxian County, Guizhou Province, the geological age in the upper part of the Qixia Formation, the Maokou Formation and the lower part of the Longtan Formation in this area are respectively Roadian, Wordian and Capitanian.
