摘　　要：新疆的黄土地貌及其遥感判读具有不同于我国黄土高原地区的一些特点。根据参与"中国1:1 000 000数字地貌制图(新疆片)"项目工作的实践和体会,从黄土地貌区的位置、色调与色彩、大小、形状、阴影、水系和纹理、植被和土壤、相关体、相关资料和野外经验等方面总结了7项关于新疆黄土地貌的遥感判读依据,并归纳了新疆黄土地貌与风沙、干燥、流水、冰缘、雅丹等地貌类型之间以及与部分特殊情况之间的一些鉴别特征。结果可为新疆未来的地貌制图及相关的科研与教学工作提供参考。Loess landform in Xinjiang and interpretation of its remote-sensed those in the Loess Plateau. Due to the special and complex physical geographi images are somewhat different from cal environment of Xinjiang, there are some difficulties sometimes in interpreting loess landform in remote-sensed images. According to the author＇ s practice and knowledge from experience in the project of 1 ： 1 000 000 digital geomorphic mapping of China （part Xinjiang）, based on geographical related analysis method, field on-site inspection and validation method, vector editing tools and spatial analysis tools of GIS software, and using a series of Xinjiang＇ s data including digital geo- morphic map （ 1 ： 1 000 000）, DEM （ 1 ： 250 000）, TM/ETM and Google Earth remote-sensed images, vegetation map （ 1 ： 1 000 000）, soil map（ 1 ： 1 000 000） and land use/land cover map（ 1 ： 100 000） （2000）, this paper puts forward seven bases for the remote sensing interpretation of loess landform in Xinjiang, which deal with such aspects as loess landform＇ s location, tone and color, size, shape, shadow, drainage and texture, vegetation and soil, related object in the remote-sensed images, and related material and field experience. Furthermore, some identification characteris- tics between loess landform and sandy desert landform, arid landform, fluvial landform, periglacial landform, yardang landform and some other special circumstances in Xinjiang, are summed up. The paper points out that： loess land- form bodies of Xinjiang usually connect with the mountains and lie on the outside edge of the mountains, and com- monly are loess hills or outer mountains covered with loess, for loess often overlaps on other terrain as a cover layer; in remote sensing images, except for the valleys, the overall color of loess landform is single and uniform, its tone and shade transition is generally gentle and gradational, and the tones of loess landform in areas of desert, desert steppe and typical steppe, are totally li
