摘要: 遥感及其技术应用和卫星技术的发展为资源环境调查提供了丰富的信息, 在人类社会经济活动中发挥着巨大作用。文章根据全国荒漠化土地调查要求及美国陆地资源卫星TM影像特点, 分析了甘肃河西地区12景、24幅TM影像色调特征及形态特征。在此基础上, 结合荒漠化土地类型划分建立了图像解译标志, 并详细阐述了TM影像解译程序。通过评价此次荒漠化土地卫星遥感调查中TM影像的特点及应用效果, 充分表明了该现代技术用于此类工作的极大成功。

Abstract: The application of remote sensing technology and the interpretation of satellite photogram provide abundant information for survey of resources environment. These information play the important role in mankind's social-economic activities. The characteristics of tones and patterns of 12 sceneries, 24 photos in Hexi area of Gansu were analysed in this paper. Combining with the classification of desertification site types, the picture's interpretation signs have been set up. The interpretation programme of the TM imagery was elaborated also in the paper. Evaluating the applied effects of the TM imagery proved that the modern technology of remote sensing had got great success in the survey of desertification land.
