中文摘要:
      选择威海双岛湾附近海滩、国际海水浴场海滩、金海滩、青叽岛以西海滩、青叽岛以东海滩、天鹅湖海滩、桑沟湾海滩、楮岛海滩、南海新区海滩和乳山银滩十处代表性岸滩进行了海滩地貌和底质调查,结合沙滩表层样品分析测试数据,对研究区海滩地貌、沉积物粒度分布特征及海滩质量进行了综合评价。结果表明:威海海滩沉积物主要包括砾砂、粗砂、中砂、细砂四种类型,其中中砂分布最广,约占所有点位的35.6%,细砂、粗砂、砾砂分别占34.4%,26.7% 和3.3%。岸滩坡度一般较缓,宽度中等以上,岸滩质量整体较好,部分岸滩受沉积物粒度影响,质量稍差。

英文摘要:
      Investigations of geomorphology and sediments of beaches were carried out in 10 representative beaches such as the Shuangdao Bay beach, the International bathing beach, the Golden bathing beach, the beach west of the Qingjidao Island, the beach east of the Qingjidao Island, the swan lake beach, the Sanggou Bay beach, the Zhudao beach, the Nanhai New District beach and the Rushan silver beach. Combining with the analysis of surface samples collected from the beaches, the beach geomorphology and the grain size distribution and quality of the beach sediments in the study areas are evaluated comprehensively. The sediments of the beaches in Weihai City are mainly composed of gravel sand, coarse sand, medium sand and fine sand. Of them, the medium sand is distributed most widely and accounts for 35.6% of all survey stations; the next is fine sand, which accounts for about 34.4% of all stations; the coarse sand accounts for about 26.7% and the gravel accounts only for 3.3%. The slope of the beaches is gentle in general and the width of the beaches is above medium. The beach quality is better on the whole, but some of the beaches are slightly worse in their quality due to the effects of sediment grain size.
