随着海洋经济的发展和人口的爆炸性增长，沿海地区正承受着巨大的压力--因为从内陆向东部发达城市中国的移民。岛屿沿海区是一个被海包围的特定生态系统，对人类活动更敏感，例如填海。利用遥感技术监测海岛近岸海域的动态变化，恢复周围外海的淤积格局及其对海岛岸线的影响是十分必要的。利用陆地卫星图像进行时间序列监测，对海岛海岸带某沙坝的变化进行监测，分析人类开发利用对沙坝的影响。结果表明，利用遥感图像进行海岸带动态监测具有很大的潜力。
As the development of marine economy and population explosion, coastal areas is suffering great pressure - because of the immigration from inland to the developed cities along east China. Island coastal zones, which is a specific ecosystem surrounded by the sea, is more sensitive to human activities, e.g. reclamations. It is essential to monitor the dynamic changes of the island coastal areas to retrieve the siltation pattern of the surrounding open-sea and their impacts to island coastlines using remote sensing technique. In this paper, a time-series monitoring using Landsat images is performed to monitor the changes of a sand dam in the island coast zone, aiming at analyzing the effects of human exploitation. The results show great potential of using remote sensing images for coast zone dynamic monitoring.
