中文摘要	在总结沙漠化土地遥感研究的基础上,对沙漠化土地遥感信息提取、沙漠化土地遥感评价指标等研究做了详细地论述,旨在探索一种有理有据而又满足当前和未来对沙漠化土地遥感信息分析的新思路.
英文摘要	The grassland desertification is becoming more serious, caused the fragile grassland ecology to worsen further. Under this kind of situation, the author summarizes the definition of desertification, and describes the study progress of the desertification remote sensing information in the Chinese and international in recent years. On this basis, the interpreter of the desertification remote sensing information is expatiated in the paper from the choice of the data source of remote sensing, the choice of the wave band, the Geometric Correction of the remote sensing image, the information strengthen of remote sensing image, mask technology, separate technology and image interpreter and so on. And on the basis of summarizing desertification remote sensing evaluation index in Chinese and international, compare synthetically, the vegetation cover, the bare sand percentage and soil character are to evaluation index of desertification. The conclusion is it is feasible to separate the type of desertification, and their distributing, and their vegetation cover to utilize the remote sensing image. The application is less about the mix-pixel separate technology in the interpreter of desertification remote sensing information. The author will extract the desertification information form remote sensing image by the separate technology and mask technology, and attempt to explore a kind of pattern process method to extract the characteristic of desertification truly. Meanwhile, the idea of the analyzing from mathematical.method is less in the research of desertification remote sensing application at present, that is, very meaningful if the figure analyzing is applied to remote sensing image information analysis of the desertification. This text aims at exploring one kind is reasonable and meeting with the new thinking of land remote sensing information analysis of the desertification in the future at present.
