| 摘 要： | 打网岗位于渤海西北岸,濒临京唐港,是滦河早期建造的沙坝。滦河改道北移之后,由于陆源泥沙减少以及京唐港防波堤的拦沙作用,打网岗侵蚀后退严重。利用多年岸滩监测资料、多期航卫片解译数据以及历史资料,研究表明:1987—2009年间岸滩年均侵蚀速率为-0.61～-5.30 m/a,东北端濒临港口防沙堤下游处侵蚀量最大,西南端人为固化稳定;同时依据不同岸段侵蚀程度的差异性,提出了打网岗岸滩生态修复方案。

| Abstract: | Dawanggang,occurring as a sand bar(built up by the Luanhe River in the past time) adjacent to the Jing-Tang harbor,is located on the northwestern coast of the Bohai Sea.Since the Luanhe River changed its course to the north and also because of the construction of the Jing-Tang harbor wave dam to prevent sand accumulation,continental silt supply to the sand bar from the river has decreased and as a result,Dawanggang has been severely eroded and retreated.The authors use yearly beach monitoring data,multi-per... |
