| 摘 要： | 利用多年实地观测数据,并结合多期遥感影像解译结果.系统分析了昌黎黄金海岸沙丘典犁地段的动态变化特征及其动因,结果表明:在盛行风作用下,受物源减少、植被固定和人为扰动等诸多因素影响.沿岸沙丘在整体向陆移动的背景下,移动距离由小到大依次为沙丘中段,北段、南段;沙丘迁移速度渐缓,由3.04 m/a减小到2.07 m/a;沙丘高度逐年降低,除个别年份高度呈现正增长外,其他年份均为负增长;沙丘向海坡坡度、背海坡坡度均减小,向海坡坡度变化更为明显.

| Abstract: | Using the Observational data of many years and information from multi-temporal remote sensing images,the paper analyzes that the characteristics of dynamic changes and the causes for typical dunes in Changli Gold Coast.The result shows that,affected by prevailing wind,the moving of the whole sand dunes to the land is at different levels because of the reducing of material source,fixed vegetation and human activity.The distances of moving sand dunes are depend on different regions,for example,sand dune of th... |
