| 摘 要： | 本文通过对天津滨海贝壳堤成因的研究，初步确定贝壳堤是全新世晚期形成的，它的形成和演化反映了近岸生源物质迁移、现代沉积过程，贝壳堤的演化模式划分为三个阶段。这对正确地揭示淤泥质平原海岸的形成机理、合理规划开发潮滩和贝壳堤资源有着重要意义。

| Abstract: | This paper researched the origin of shell ridges in the coastal area of Tianjin and preliminarily determined the late Holocene age of their formation. The formation and evolution of shell ridges demonstrate a migration of coastal biogenic material and present-day sedimentary process. The evolution pattern of shell ridges can be divided into three stages. The research is importantly significant for properly revealing the formation mechanism of the muddy plain coast and rationally planning and utilizing littoral plain and shell ridges resources. |
