摘要：以覆盖科尔沁沙地１３个旗县的６景ＴＭ影像为例，简介了以计算机屏幕解译这种技术路线制作卫星影像分类图的过程，论述了卫星遥感技术监测荒漠化土地变化和作出环境发展趋势评估的潜力。指出对待盐渍化和沙化这两个问题，对不同区域应各有侧重，最后介绍了联合国粮农组织（ＦＡＯ）的土地分类原则，用土地单元、土地利用类型及附加特性注记地类的方法。
A technical methodology of computer screen interpretation is introduced to produce satellite imagery classification map on an area of about 100 000 km 2 of Kerqin Desert in eastern part of Inner Mongol with a mosaic of 6 TM scenes. The potential of remote sensing technique is assessed for change monitoring of desertified land and for environment development tendency estimation. The two problems of salinization and desertification should be treated in different order according to regional situation. The FAO classification and notation principle by land unit,land use and added characters was used in the procedure.
