【摘要】 论述了我国主要海岸侵蚀区的侵蚀现状、特点及原因。指出我国海岸侵蚀主要有两种类型 :长周期趋势性的海岸侵蚀和短周期的暴风浪侵蚀现象。提出海岸侵蚀的防治对策 :“保堤必须保滩”,“全线防护变成线段防护”,在不同地区建造丁坝、潜坝、护坎坝、离岸堤以及它们的相互组合形式。这为海岸侵蚀的防护提供了理论依据 ,对海岸带的综合管理有重要意义更多还原

【Abstract】 The erosion status,characteristics and reasons of main coastal erosion zone of China were briefly analyzed.Coastal erosion mainly has two types:Coastal erosion phenomena of long period and tendency,and coastal erosion phenomena of very rough sea of short period. It was put forward to prevention and control strategy of coastal erosion, that is protecting dike must protect beach, protection of the whole coastal line should change into protection of line segment, and in different zones, spur dike, under dike, protect ridge dike and free on board dike and their combine pattern may be constructed. These provided theoretical base for protecting of coast erosion, it has importance significance to comprehensive management of coastal zone.更多还原
