摘要
全新世海侵高峰过后，海平面一直处于幅度不大（约１ｍ左右）的振荡运动状态．对应四次“小高海面”时期，天津滨海平原上堆积了四道贝壳堤．历史上，黄河在本区入海。
Research has revealed that the relative sea-level has continuously been in the state of oscillation with an amplitude of approximately 1msince the highist sea-level of Holocene passed. Corresponding to four micro-higy sea-level phases, four cheniers were accumulated on Tianjin coastal plain respectively in the last 5000 years. The rapid deposition in the estuary area of Huanghe rever resulted in less sorts of sea-shell which made up cheniers.
