摘　　要：选择2013年国产ZY-3卫星影像和2004年SPOT-5卫星影像,开展龙口至芝罘岸段的海岸侵蚀遥感监测,给出了9a间该岸段海岸侵蚀的空间分布状况,并从海岸侵蚀速率、海滩宽度侵蚀模数、土地损失面积和海岸侵蚀强度四个方面进行了海岸侵蚀灾害特征分析。结果表明:1)2004-2013年间龙口至芝罘海岸有9个岸段发生侵蚀,分别位于龙口东海旅游度假区、龙口东庄、蓬莱小皂村、套子湾西侧和东侧,发生侵蚀的岸段都属于平直的砂质岸线;2)9a间,侵蚀岸段的平均侵蚀速率为2.2m/a,平均海滩宽度侵蚀模数7.38%,因海岸侵蚀共损失土地面积91 879m2;3)给出了基于侵蚀速率和侵蚀宽度模数的海岸侵蚀强度信息,其中基于侵蚀速率的侵蚀强度多数是中侵蚀和强侵蚀,龙口市东庄的海滩是严重侵蚀,基于侵蚀宽度模数的侵蚀强度多数是强侵蚀,蓬莱市小皂村的海滩是严重侵蚀。The ZY-3remote sensing images made in China in 2013and the SPOT-5images in 2004are selected for the study of the remote sensing monitoring of coastal erosion along the coastal segment between Longkou and Zhifu.The spatial distributions of the coastal erosion along this segment in the last 9years are given,and the disaster features of the coastal erosion are discussed from the following four aspects：coastal erosion rate, beach width erosion modulus,land area loss and coastal erosion intensity.The results show that：1）Nine segments along the coast between Longkou and Zhifu suffered from erosion from 2004to 2013.All of them belong to a straight sandy coastline and are located respectively in the Longkou Donghai tourism resort,the Longkou Dongzhuang village,the Penglai Xiaozao village and the western and eastern sides of the Taozi Bay;2） In period of nine years,the eroded coastal segments are 2.2m/a in the average erosion rate,7.38%in the average beach width erosion modulus and totally 91 879m2 in the land loss caused by the erosion;3）The information about the coastal erosion intensities is given based on the erosion rate and the width erosion modulus.The erosion intensities based on the erosion rate belong to mostly a moderate erosion and a strong erosion,of which the Longkou Dongzhuang beach is a serious erosion,whereas those based on the erosion width modulus belong to mostly a strong erosion,of which the beach at Penglai Xiaozao village is a serious erosion.
