摘要
介绍了国内外地表覆盖的多项工作,以LANDSAT系列卫星影像为主要数据源,辅以参考数据源,按照优化设计的地表覆盖分类流程,制作了柬埔寨2005、2010、2015年的区域地表覆盖成果,并结合相关资料分析了地表覆盖与农、林、环保的关系。结果表明,本研究能够较好地监测区域和国家的地表覆盖变化,为亚太地区发展中国家的可持续发展提供技术支持。
This paper introduced the domestic and overseas works of land cover at first.And then,taking Landsat satellites’images as main data source,combining with other reference data,according to optimally designed workflow of land cover classification,the paper produced land cover results of Cambodia by the year of 2005,2010,2015.At last,combined with related materials and information,the paper implemented the thematic analysis on the relationships between land cover and agriculture,forest,environment.The result shows that this research is suitable for monitoring regional or national land cover changes,and gives a technical support on sustainable development for developing countries of Asia-pacific countries.
