摘要
河北省沙质海岸是渤海海岸侵蚀灾害最严重的区段之一,海岸侵蚀主要表现于海滩沙粗化,滩肩迅速变窄,滩坡变陡,基岩裸露的比率增多。岸线蚀退率达1.5～3.5m/a,严重制约了海滩旅游事业。整治海难,刻不容缓。采取岸外潜坝和丁坝群等人工建筑物和大量补沙相结合的海滩养护方法应是当前最迫切、最科学和最实际的方法,只有南段沙丘和沙坝-泻湖岸段可采用植树种草的生物学方法护岸。
Sandy coast in Hebei province is one of the most heavily eroded coast along Bohai Sea. The coastal erosion mainly appears as beach sands coarsening, berm narrowing, gradient becoming sharp and the rate of bare rocks increased, and the rate has reached to 1.5-3. 5m/a, which seriously restricts the development of the beach tourism. Thus, it is no delay to regulate the coast. At present, engineering with hard structures such as offshore submerged breakwater and groin combining with the artificial beach nourishment by adding huge amounts of sands is the best methods for the beach protection. And only in the south dune and sandbar-lagoon segments, the biology method by planting and growing can be adopted to protect the beach from erosion.
