摘　　要：宁夏的含(竹蜓)地层出露较好,剖面和柱状剖面有7处.含(竹蜓)地层自下而上为:下石炭统臭牛沟组、中卫组,上石炭统羊虎沟组,上石炭—下二叠统太原组.(竹蜓)动物群有15属68种及亚种,其中1新种.可建立(竹蜓)化石带 Eostaffella-Mediocris 带 (C_1), Profusulinella 带 (C_2~1) 及 Sphaeroschwagertna 带 (P_1~1),并与甘肃靖远及华北地台其它地区的(竹蜓)化石带对比.In the Ningxia Hui Autonomous Region situated in the eastern part of Northwest China, four fusulinid-bearing formations are distributed around Shizuishan, Zhongning, Zhongwei and Tongxin, with their sequence and ages recognized as the Taiyuan Formation (late Late Carboniferous to early Early Permian), the Yanghukou Formation (early Late Carboniferous), the Zhongwei Formation (late Early Carboniferous), and the Chouniukou Formation (early Early Carboniferous). The seven stratigraphic sections of these formations include: 1) section of the Yanghukou and Taiyuan For mations at Shangheyan of Zhongwei; 2) section of the upper Chouniukou Formation and the Zhongwei Formation at Jiaoyucbuan of Zhongwei; 3) section of the Zhongwei Formation at Chenmazijing of Zhongning; 4) section of the Taiyuan Formation at Xiaohonggou of Tongxin; 5) section of the Yanghukou Formation at Shabatai of Shizuishan; 6) columnar section No. 123 of the Taiyuan For- mation in Shizuishan and 7) columnar section No. 131 of the Taiyuan Formation in Shizuishan. The fusulinids described and illustrated here comprise 68 species and subspecies (including 1 new species) belonging to 15 genera.
