摘要: 彩色红外航空象片是遥感图象信息源中的-个重要片种,在我国它日益广泛地被用于各专题内容的判读。对彩色红外航片性能简要叙述之后,重点论述沙漠化程度和沙漠化因素的解译,通过影象特征,如形状、大小、色调、阴影等等,提供判读沙漠化土地发生的程度、趋势和造成的自然及人为因素的信息,以提高沙漠化地区环境监测的准确性和工作效率。

Abstract: The colour infrared aerial photo is one of the key sort of the remote sensing imagery information sources. In China, this sort of photo is extensively utilized for the interpretation of different monographic contents. In the study, the property of colour infrared aerial photo and its interpretive characteristics are briefly discussed, and stressly discribed the interpretations of the degree of desertification and factors of desertification. The features of desertification on photo are described from the viewpoints of the shape, size, colour and shadow. The interpretative indicators of land desertification which caused by physical and human factors are introduced. These indicators are summerized on the basis of the experiences in the field of aerial photo interpretation in last decads,
