| 摘 要： | 利用多期遥感数据,监测天津滨海新区近10年来海岸线的冲淤变化及潮滩利用,结合历史海岸线资料,对其变迁特征和成因进行分析。结果表明,近10年来,该地区海岸线总体快速向海推进,特别是在2007年以后推进速率明显增大,最大规模推进集中在海滨浴场至永定新河河口岸段,约13.7 km。围海造陆、港口建设等人为活动是其快速推进的主导因素。海岸侵蚀作用多发生在歧口河至青静黄排水渠岸段和大神堂村至涧河口岸段,且大神堂村至涧河口岸段比较显著,平均侵蚀速率约10m/a,需要密切关注和重点防范。

| Abstract: | Shoreline of the Binhai New Area have changed quickly in the past ten years.To detect its spatio-temporal changes and causation,a set of remote sensing images and correlative historical documents were collected and the shoreline information were chosen out and interpreted.Results show that the shoreline was in a continuous siltation and extension process in principle,especially since 2007.The max extension,about 13.7 km,existed in the Haibin Bathing Place to the Yongding New River estuary shoreline sector.T... |
