摘要:利用1987、1990、1995、2000、2005、2010、2015、2017共计8期40景覆盖海南岛全境的Landsat TM//OLI数据,结合野外调研资料,建立6种海岸线解译标志和提取规则。运用ENVI5.2和ArcGIS10.1软件,通过目视解译与判读,采用数字矢量化方法获取海岸线的分布与类型信息,经过精细的修改与验证工作,得到海岸线分布和类型数据集。本数据集可用于海岸线时空变化分析、岸线利用程度与陆海格局演变特征等研究,能够清晰地反映时间序列数据支持下的海南岛海岸线环境变迁特征。

Abstract & Keywords
Abstract: Six types of coastline interpretation markers and extraction rules were established based on a combination of the Landsat TM//OLI data of 40 scenes (with a full coverage of Hainan Island) for eight periods during 1987 – 2017 and field investigation data. The position and type of coastlines are obtained by visual interpretation and digital vectorization, assisted by ENVI5.2 and ArcGIS10.1 software. The results are then carefully verified and modified. The data sets can be used to analyze the temporal and spatial variation of the coastlines, or to study the characteristics of coastline exploitation and the evolution of land and sea pattern. It clearly reflects the characteristics of the coastal environmental changes of Hainan Island.
Keywords: Hainan Island; coastlines; position of coastlines; type of coastlines; ecological environment
