摘　　要：海岸侵蚀是当今全球海岸普遍存在的海洋地质灾害现象,通过实地勘查对河北省砂质海岸侵蚀灾害进行研究,借助历史资料,选取了海岸地貌类型、岸线曲度、侵蚀速率、海滩发育空间、泥沙补给和堤防设施六个评价指标,对河北省砂质海岸侵蚀灾害进行了危险性评价。评价结果表明:高危区岸线长度46.11 km,中危区102.54 km,低危区59.95 km,所占岸线比例依次为22.11%、49.16%及28.73%。The coast erosion is a common phenomenon of marine geological disasters in the world.This article conducted the study of sandy coast erosion disaster by field surveys in Heibei province. According to the historical documents, six evaluation indexes were selected to evaluate the risk of erosion on the sandy coast, including the coast landform, shoreline curvature, erosion rate, beach development zone, sediment supplement and embankment project. As a consequence,the length of shoreline in high risk areas was 46.11 km, 102.54 km in the middle, and 59.95 km in the low areas, the proportion of shoreline accounts for 22.1%, 149.16%, 28.73% respectively.
