国家尺度土地利用/覆被变化遥感监测方法

Remote Sensing Monitoring Methods of Land Use/Cover Change in National Scale

以中国科学院国家资源环境数据平台土地利用/覆被专题数据库的建设为背景,总结了国家尺度土地利用/覆被变化涉及的主要遥感监测技术和方法,包括基于遥感监测的土地利用/覆被分类系统、遥感信息源、土地利用/土地覆盖信息提取方法、土地利用分类1 km栅格成分数据构建技术以及土地利用分类面积汇总技术,并在此基础上分析了国家尺度土地利用/土地覆盖专题空间数据库应用现状和未来发展前景。

Taking construction of land use/cover database in national resource and environment data platform as a background,this paper summarized the RS monitoring technology and methods involved in land use/cover change of national scale,including land use classification system based on remote sensing monitoring,remote sensing information sources,land use/cover infonmation extraction methods,construction methods of 1km resolution grid percent data,area summarization technology for land use types,based on which the application status and future development prospect of spatial database about the land use/cover in national scale were analyzed.
