摘要
本文基于GIS技术对1977—2017年芝罘连岛沙坝的岸线变化和海湾冲淤动态进行分析,发现了连岛沙坝的变化情况及其影响机制。结果表明:在此期间,连岛沙坝东西两侧始终处于向海推进趋势;在快速城市化进程下导致沙坝附近的岸线总体长度增加,形状趋于复杂,自然海岸消失,人工海岸建设不断向海延伸;通过等深线反映附近海域冲淤变化,主要体现在芝罘湾侧以人为干预为主,近岸海域的港口、码头等地侵蚀剧烈,海湾中心呈严重片状淤积。本研究对明确人类活动、流域水沙及水动力环境变化等对芝罘连岛坝地貌演变的影响,以及本地区海岸带的可持续利用具有重要指导意义。
With the support of GIS technology, analysis of the shoreline changes of Zhifu tombolo and the dynamics of erosion and deposition in the bay from 1977 to 2017 was conducted to study the changes of the tombolo and its influence mechanism. The results show that during this period, the east and west sides of the tombolo have always been seawards. Under the rapid urbanization process, the overall length of the shoreline near the tombolo has increased, the shape has become more complex, the natural coast has disappeared, and the construction of artificial coasts has continued to move seawards. The isobath reflects that the erosion and siltation changes in the nearby sea area is mainly reflected in the human intervention on the side of the Zhifu Bay. Ports and wharves in the coastal waters are eroded severely, and the center of the bay is seriously silting. This study has important guiding significance to clarify the changes in human activities, water and sand and hydrodynamic environment in the river basin, which in turn affect the landform evolution of the Zhifu tombolo, and the sustainable use of the coastal zone in the region.
