根据150多个钻孔的微体古生物资料，对渤海西南海岸平原第四纪海侵命名问题进行了探讨。我们认为古潮汐和沉积对微体古生物化石的分布有很大的影响。根据目前的技术水平，建立海侵层序必须具备以下条件：化石证据充分；明确气候;稳定的沉积层。在建立海侵时，必须提出海侵时相概念的内容，并对其生物相、沉积相和古气候学进行综合分析。
Based on micropalaeontological information of over 150 drill holes, this paper discusses the problem on the naming of Quaternary transgressions in the west-southern coast plain of Bohai Sea. We consider that palaeotide and sedimentation have a great influence on the distribution of micropalaeontological fossils. In view of the present technical level, it is necessary for transgression sequence to be established under the following conditions: full evidence of fossils; clear climate; and stable sedimentary beds. In establishing a transgression, its contents of time and phase concept must be proposed, and its biofacies, sedimentary facies and palaeoclimatology must be analysed synthetically.
