| 摘 要： | 草原沙化是国内外关注的重大生态环境问题。本文利用遥感数据，在“3S”（RS，GIS，GPS）集成技术的支撑下，采用地面调查方法，建立遥感影像与地面数据的数学模型，对若尔盖县沙化草，-原开展遥感监测。利用不同地物在遥感影像上的色调与形态差异，建立草原解译标志与分级指标体系，获取沙化草原面积、分布和等级情况。本研究为进一步开展西川省草原沙化调查提供了技术支持，为治理草原沙化提供了科学参考。．

| Abstract: | Desertification of grasslands which is concerned all over the world. With is one of the most serious environmental problems the support of 3S （remote sensing, geographic infor- mation system and global positioning system） technology, remote sensing image is used, including ground investigation. This paper analysed remote sensing monitoring of sandy grassland in ruoergai county by establishing the model of remote sensing image and ground data. Based on the differ- ence of tones and patterns, the image＇s interpretation and classification index system had. been established, the area and distribution and level of sandy grassland had been gained. The research finding gived further technical support to the investigation of sandy grassland in Sichuan province. At the same time, the data presented a scientific view for controlling grassland desertification. |
