摘　　要：福建宁化上石炭统类生物地层自下而上划分为4带3亚带:1)Pseudoendothyraninghuaensis带,2)Fusulina-Fusulinella带,其中包括Fusulinellahelenae-Pseudostaffellapaxadoxa亚带、Beedeinamayiensis亚带和Fusulinaquasicylindrica亚带,3)Protriticitesobsoletus带和4)Montiparusmontiparus-Quasifusulinafusiformis带。该区生物地层可与我国华南、华北和西北沉积区以及俄罗斯地台同期地层进行对比,其年代地层归属于上石炭统达拉阶至逍遥阶下部,相当于国际地层表上石炭统(宾夕法尼亚亚系)的莫斯科阶和卡西莫夫阶。The Upper Carboniferous strata are well developed and widespread in Ninghua district of Fujian. Based on the geological distribution of the fusulinids, the Late Carboniferous fusulinids may be divi- ded into 4 zones and 3 subzones in descending order: Montiparus montiparus-Quasifusulina fusiformis Zone Protriticites obsoletus Zone, Fusulina-Fusulinella Zone (Fusulina quasicylindrica Subzone, Beedeina mayiensis Subzone, and Fusulinella helenae-Pseudostaffella paxadoxa Subzone) and Pseudoendothyra ninghuaensis Zone.These zones or subzones were first discovered in Fujian, and can be correlated with the Montiparus montiparus Zone, Fusulina-Fusulinella Zone and fusulinid Zone of South and North China. They are most probably equivalent to the fusulinid zones of Moscow Syneclise in Russia in the same age, and referred to the Upper Carboniferous Dalan Stage to the Lower Xiaoyao Stage of China, corresponding to the Moscovian and Kasimovian stages of Pennsylvanian in the International Stratigraphic Chart.
