摘　　要：以中国科学院土地利用/土地覆被分类系统和IGBP土地利用/土地覆被分类系统为例,分别按照直接转换、间接转换、分类后再转换3种转换关系制定转换规则,以西北农牧交错带为实验区,利用从中国科学院资源环境数据中心获取的实验区2015年土地利用/土地覆被数据以及遥感影像、野外考察数据等,按照制定的规则,对土地利用/土地覆被分类系统进行了转换和验证.结果表明:本研究所制定的土地利用/土地覆被分类系统转换规则科学合理;经过分类系统转换后的土地利用/土地覆被数据精度较好.本研究对于其他分类系统间土地利用/土地覆被数据类型的转换具有参考价值,对进一步的区域变化研究具有重要意义.Taking the landuse/landcover classification system of the Chinese Academy of Sciences and the IGBP landuse/landcover classification system as examples,conversion rules were fonnulated according to the three conversion relationships:direct conversion,indirect conversion and conversion after classification.The northwest agro-pastoral zone was used as the experimental area.The landuse/landcover data in the experimental area obtained from the Resource and Environmental Data Center of the Chinese Academy of Sciences,remote sensing images and field survey data were used to test the landuse/landcover the conversion methods of the classification systems according to established rules.The results showed that the developed rules used for the conversion in this paper were scientific and reasonable;the precision of the landuse/landcover data was trustworthy after conversion.This study has a reference value for the conversion of landuse/landcover data types in other classification systems and other areas,and is of great significance for further research into regional changes.
