摘　　要：在全面分析朝阳港潟湖湿地发育的主要因素的基础上,探讨了中全新世以来朝阳港潟湖湿地的演变过程。朝阳港潟湖湿地演变可以划分为:古海岸线形成、水下沙坝发育、青矶岛连岛坝发育和现代潟湖湿地发育四个阶段。青矶岛连岛坝是泥沙横向移动和纵向移动共同作用的结果,青矶岛连岛坝的形成促使朝阳港由原生构造湾逐渐演变为潟湖型次生湾。The evolution processes of the Chaoyanggang lagoonal wetland since the middle Holocene have been discussed on the basis of systemic analyses of the main factors in developing of the wetland. The evolution of the Chaoyanggang lagoonal wetland can be subdivided into four stages： the formation of paleocoastal line, the development of underwater sand bar, the formation of Qingji Island tombolo and the development of recent lagoonal wetland. The Qingji Island tombolo is thought to be formed mainly by the coactions of cross-shore and parallel-shore sediment movements. It is the formation of the Qingji Island tombolo that impels the evolution of the Chaoyanggang from a primary tectonic bay into a secondary lagoonal bay
