| 摘 要： | 秦皇岛地区旅游性海滩的侵蚀主要是人类所实施的以水库为主的河流水利工程而产生的海岸效应。在区域性海滩普遍遭受侵蚀状态下，沿海港口工程又通过三种不同形式第滩发育施以影响，其一是对沿岸泥沙流的拦阻，其二为在局部岸段形成完全或不完全波影区，其三为人工岬湾的形成，港工引成的海滩淤积体特征是海滩变宽、变缓及海滩砂细化。文中最后讨论了侵蚀性海滩向演化的发育空间问题。

| Abstract: | The Qinhuangdao beach is located in the northern coast of the Bohai Bay. In this area, tour beach has been eroding. The main reason of the beach erosion is reseryiors constructed on rivers. Under the erosion state of the region beach,the harbour engineering produced a great impact on beach development by three ways: (1) longshore drift and current blocked ; (2) the wave shadow formed ; and (3) a bay between manmade headlands formed. The consequence is to make the beach wide, gentle and the sand thined. In the end of the paper, the question of beach evolution space was discussed. |
