摘　　要：我国非海相白垩纪介形类化石可以划分为7个组合:1)分布于我国西北和西南地区欧特里沃期巴列姆期的Jingguella-Minheella-Pinnocypridea组合;2)分布于我国西北和西南地区巴列姆期的Cypridea-Latonia-Darwinula组合;3)阿普特期阿尔必期的Cypridea(Morinina)-Bisulcocypridea-Mongolocypris组合;4)分布于我国东北、中部及东部地区欧特里沃期巴列姆期的Cypridea-Mongolianella-Darwinula组合;5)分布于我国东北、中部及东部地区巴列姆期阿普特期的Cypridea(Cypridea)-Cypridea(Ulwellia)-Limnocypridea组合;6)塞诺曼期塞农期的Cypridea-Triangulicypris-Sunliavia-Lycopterocypris组合;7)坎潘期马斯特里赫特期的Talicypridea-Cypridea-Quadracypris-Candona组合。依据以上7个介形类化石组合,我国22个地区含介形类的73个地层单元(群/组)得到了对比。On the basis of the characteristic composition of ostracods in non-marine Cretaceous strata, 7 ostracod assem- blages of China have previously been established, and are preliminarily reviewed herein. They are as follows 1） Hau- terivian-Barremian Jingguella-Minheella-Pinnocypridea assemblage in northwestern and southwestern China; 2） Barremian, Cypridea-Latonia-Darwinula assemblage in in northwestern and southwestern China; 3） Aptian-Albian Cypridea （Morin- ina）-Bisulcocypridea-Mongolocypris assemblage; 4） mainly Hauterivian-Barremian, Cypridea-Mongolianella-Darwinula assemblage in northeastern, central, and eastern China; 5） Barremian-Aptian, Cypridea （Cypridea）-Cypridea （Ulwel- lia）-Limnocypridea assemblage in northeastern, central, and eastern China; 6） Cenomanian-Santonian Cypridea-Trianguli- cypris-Sunliavia-Lycopterocypris assemblage; 7） Campanian-Maastrichtian, Talicypridea-Cypridea-Quadracypris-Candona assemblage. Seventy-three ostracod-bearing formations/groups in 22 regions of China are analyzed and correlated.
