摘　　要：以《中国地层指南及中国地层指南说明书》(修订版 )为依据 ,以地层单位命名的一般规定为准绳 ,以地层单位命名的优先权为法则 ,对黑龙江省东部地区中生代晚期海陆交互相地层龙爪沟群组级岩石地层单位名称的正确使用问题 ,进行了较为详细的讨论。龙爪沟群自下而上可划分为三个组 ,组名应为东胜村组、裴德组及云山组 ,其他的所有名称均应被视为前三组的后出同义名 ,并停止使用 ,以免造成不应有的混乱。东胜村组与鸡西群下部的滴道组不能完全对比。According to the “Stratigraphic Guide of China and Its Explanation” and based on the general rules for naming stratigraphic units and the principles of priority, a fairly detailed discussion is made on the correct use of the formation-rank names of the lithostratigraphic units of the Mesozoic paralic facies of the Longzhaogou Group in the east of Heilongjiang Province. The Longzhaogou Group may be ascendingly divided into three formations, namely the Dongshengcun, Peide, and Yunshan Formations, and the remaining names should be regarded as synonymous with the afore-mentioned three names and should be abandoned in order to prevent undue confusion. The Dongshengcun Formation can not be perfectly correlated with the Didao Formation in the lower part of the Jixi Group.
