【摘要】 为了查清辽宁省海岸的蚀淤等级和分布,从1990年和2007年遥感图像中提取了17年的岸线变化信息,结合辽宁省908专项海岸带海岸侵蚀特征的调查资料,对全省海岸蚀淤情况进行了等级划分,并对其形成原因进行了分析与评价。结果表明,砂质海岸侵蚀较重的区域主要分布在绥中和熊岳一带,黄海岸段的砂质海岸基本稳定,基岩海岸侵蚀较重的区域主要分布在老铁山一带,粉沙淤泥质海岸侵蚀较重的区域分布在庄河一带。摸清辽宁省海岸蚀淤等级分布,对海岸整治与修复、海岸侵蚀灾害的防治与防护以及海岸带管理具有一定的指导意义。更多还原

【Abstract】 To identify grades and distribution of coastal erosion in Liaoning,we analyzed the coastline information of 1990 and 2007,in combination with the comprehensive investigation data,and appraised coastal erosion and siltation characteristics in Liaoning Province.We found that Suizhong and Xiongyue coast were eroded seriously,while north Huanghai coast in Liaoning Province was steady in the sandy coast.Laotieshan coast was eroded seri-ously in the rocky coast,and the Heidao coast in Zhuanghe was eroded seriously in the silty mud coast.Indentifica-tion the grades and distribution of coastal erosion and siltation in Liaoning Province is important to coastal repair,coastal erosion prevention,and coastal management.更多还原
