| 中文摘要 | 将大陆岸线分为自然岸线、人工岸线2大类以及11个二级类,基于地形图与遥感影像,结合野外考察工作建立详细的技术规范,提取20世纪40年代以来6个时相的中国大陆海岸线;针对提取的结果,应用直接对比法计算实际误差,基于地图学和遥感信息提取的理论计算“理论最大允许误差”,二者对比表明:基于多源数据提取多时相岸线的技术方案可行,多时相岸线的实际误差均远远低于“理论最大允许误差”,精度较优;基于地形图提取的20世纪40年代和60年代时相岸线,精度总体上低于基于30 m分辨率遥感影像提取的多时相岸线,而且20世纪60年代时相受多源数据融合的影响而精度最低;基于环境与灾害监测预报小卫星 CCD 数据提取岸线,受影像畸变和几何纠正精度的影响,精度略低于基于Landsat影像提取的结果,但同样基于Landsat影像提取的岸线,新近时相的精度明显优于早期时相。本研究可为岸线变化研究以及海岸带综合管理等提供有力的支持。 |
| 英文摘要 | According to technical manual established on the basis of topographic maps, remote sensing images and field surveys, six phases of coastline of mainland China since 1940s were extracted. The actual errors were calculated by comparing the coastline with field measurement data directly, and maximum allowable error was calculated according to the theories and techniques of line feature data extraction from topographic maps and remote sensing images. Furthermore, comparison between actual error and maximum allowable error was adopted to determine the acceptability and availability of the coastline by further studies. It shows that, the technical scheme established coastline extraction was effective, and the accuracies of mainland coastline in six phases were acceptable. Coastline in 1990, 2000, 2010 and 2012 extracted based on remote sensing images had higher accuracy than those in 1940s and 1960s extracted based on topographic maps. Coastline in 1960s had the lowest accuracy because of various data source and data fusion. Coastline in 2012 extracted based on HJ-CCD images had a little bit lower accuracy than coastline in 2010 extracted based on Landsat images. However, with respect to coastline in 1990, 2000 and 2010, which were all extracted based on Landsat images, the newer phase had higher accuracy than the older one. This study will provide good support for coastline change detection and integrated coastal zone management practice. |
