摘　　要：在分析台风“利奇马”在渤海湾引发的风暴潮特征后认为:台风“利奇马”在进入山东半岛后路径出现的明显西折并长时间徘徊少动导致渤海湾持续8级以上东北风,是引发重大风暴潮灾害的原因。为了定量描述沿岸灾害,开展了东营市新户镇沿岸无人机灾害调查航拍,基于高分辨率影像对比分析统计,航拍区域内74%的沿岸海堤和16%的养殖鱼塘损毁严重。This paper analyzes the characteristics of the storm surge caused by typhoon Lekima in the Bohai Bay and identifies the reasons for the severe storm surge disaster.It is found that typhoon Lekima turned westward obviously after entering Shandong Peninsula and lingered for a long time of period,which caused sustained northeast wind stronger than force 8 and the severe storm surge disaster.In order to quantitatively describe the coastal disaster,a unmanned aerial vehicle(UAV)disaster investigation was carried out along the coast of Xinhu Town,Dongying City.Based on the comparative analysis and statistics of the high-resolution images,it is found that 74%of coastal seawalls and 16%of mariculture area in the aerial area were seriously damaged.
