摘　　要：进入20世纪50年代以来,我国海岸侵蚀日趋明显,一些海岸带资源或油田设施遭到破坏。针对我国黄河三角洲和长江三角洲海岸线的侵蚀现状,分析了我国海岸线侵蚀的主要因素:河流泥沙减少;海平面的上升或海洋动力因素增强以及人为因素的影响。并对目前我国所采用的海岸防护措施进行了分析。提出了我国海岸防护工程类型较多,应根据海岸侵蚀的特点采用不同的措施或多种形式组合,因势利导,使工程达到最好的防护效果。Since 1950s＇ coastal erosion has been more and more serious in China. Coast erosion has threatened coastal resources or oil-field measures. According to the erosion status quo of the Yellow River delta and the Yangtze river delta in China, the authors studied the main causes of coastal erosion as follows： the decrease of sediment discharges, rising of sea level or increase of ocean dynamical factors and human heing activities etc. Based on the analysis of coastline erosion and current precaution measure in China, prevention and control strategy of coastal erosion was put forward, that is according to erosion characteristics in different zones, taking different protecting measures. These provided theoretical base for coast protection and made precaution measures more effective.
