| 摘 要： | 本文根据实际调查资料对秦皇岛地区海岸侵淤活动进行了分析，论述了控制条件和对滨海资源环境的危害。得出近50多年来，秦皇岛123．5km长海岸发生过6种不同形式的侵淤活动，有82．69km岸段发生不同程度的侵蚀活动，占总岸段的67％。海岸侵蚀的原因除风暴潮影响外，主要是海岸带物质补给来源持续减少和人工采挖砂石。海岸侵蚀活动除威胁滨岸工程设施安全外，还严重破坏旅游资源和土地资源，加剧海水入侵活动。

| Abstract: | The paper analyzes coastal erosion and silting up in the Qinhuangdao area and discusses the constraints on coastal erosion and silting and their harm to coastal resources and environment based on information obtained from on-site investigation.The main conclusions are as follows:in the past 50-odd years,the 123.5km long coastline of Qinhuangdao has undergone six activities of erosion and silting up in different forms,of which the 82.69km long coastline has undergone erosion to various degrees,accounting for 67% of its total.Besides the storm tide impact,the main causes for coastal erosion are due to the continued decrease of material supply and manual extraction of sand and gravel.Coastal erosion can seriously destruct tourism resources and land resources and aggravate invasion of seawater besides threatening the safety of coastal engineering facilities. |
