摘要:
海滩对风暴的响应是一个复杂的过程,尤其在连续风暴发生时。本研究利用Argus视频监测系统拍摄的连续图像,从海滩地貌、剖面、海滩滨线、海滩宽度等方面,定量分析了舟山东沙海滩对连续风暴“马勒卡”和“暹芭”的响应特征,并初步探讨了影响海滩地形地貌变化对连续风暴响应的因素。结果表明:(1)风暴“马勒卡”发生后海滩单宽体积变化量平均值为-73.75m3/m,风暴“暹芭”发生后海滩单宽体积变化量的平均值为-54.56m3/m,风暴“马勒卡”使整个海滩滨线平均后退14.75m,风暴“暹芭”使得海滩滨线相对于两次风暴前后退10.91m;(2)在海滩自身因素、外部动力因素以及人类活动等共同作用下海滩对连续风暴产生了复杂的响应。

Abstract:
Beach response to storms is a complex process. We used the continuous images taken by the Argus video monitoring system and analyzed quantitatively the response of Dongsha beach to storms in the aspects of beach geomorphology, profile, beach shoreline, and beach width. We quantified the beach response to two continuous storms Malakas and Chaba, and discussed the factors affecting the response. The results show that the average value of beach volumetric change after the storm Malakas was -73.75m3/m, and that after storm Chaba was -54.56m3/m. Storm Malakas caused the average retreat of 14.75m of entire beach shoreline, and that by Chaba was 10.91m from the shoreline state before the two storms. Therefore, interaction among the nature of each beach, external dynamic factors, and human activities complicated the responses to the two continuous storms in the Dongsha beach.
Key words:  Argus video monitoring system  Dongsha beach  continuous storms  beach response to storm
