| 摘要: |
| 六枝-盘县地区的早二叠世隆林期地层，相区分异明显、篮类化石数量巨大。各相区篮类化石群落特征差异较大：半局限台地相为Staffella—Nankinella—Pisolina；台地边缘生物滩（礁）相为Parafusulina—Pseudofusulina;斜坡-盆地相为Pseudofusulina，进一步划分为近岸碳酸盐上缓坡环境的Staffella-Parafusulina-Wentzellophyllum群落、远岸碳酸盐上缓坡环境的Pamirina-Schwagerina-Pseudofusulina群落、碳酸盐下缓坡环境的Pseudofusulina Robustoschwagerina-Kepingophyllum群落和盆地环境的Pseudofusulina-Schwagerina-Verbeekiella群落。 |

| Abstract: |
| The fusulinid communities are quite variable in the Longlinian(Early Permian) strata in distinct sedimentary environments in the Liuzhi-Panxian region,Guizhou: Staffella-Nankinella-Pisolina community in the semi-restricted platform facies;Parafusulina-Pseudofusulina community in the platform-margin organic shoal reefs facies,and Pseudofusulina community in the slope-basin facies.Four communities may further be recognized for the last one outlined above,including: Staffella-Parafusulina-Wentzellophyllum community in the nearshore upper carbonate ramp environment;Pamirina-Schwagerina-Pseudofusulina community in the offshore upper carbonate ramp environment;Pseudofusulina-Robustoschwagerina-Kepingophyllum community in the lower carbonate ramp environment,and Pseudofusulina-Schwagerina-Verbeekiella community in the basin environment. |
