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，在经济活动中发挥着巨大作用。本文根据美国陆地资源卫星TM影像特点，分析了若尔盖县草原沙4ETM影像色调特征，同时根据草原沙化在遥感影像上的特征，建立图像解译标志，获取若尔盖县草原沙化分布和面积情况。为进一步开展四川省草原沙化调查提供技术支持，为宏观决策者实施草原沙化治理提供科学依据。
遙感及其技術應用和衛星技術的髮展為資源環境調查提供瞭豐富的信息，在經濟活動中髮揮著巨大作用。本文根據美國陸地資源衛星TM影像特點，分析瞭若爾蓋縣草原沙4ETM影像色調特徵，同時根據草原沙化在遙感影像上的特徵，建立圖像解譯標誌，穫取若爾蓋縣草原沙化分佈和麵積情況。為進一步開展四川省草原沙化調查提供技術支持，為宏觀決策者實施草原沙化治理提供科學依據。

Desertification of gassland is one of most serious environmental problems which is concerned all over the world. technology, With the support of 3S （remote sensing, geographic information system and global posmonmg system） remote sensing image i,~ used, including ground investigation. This paper analyses remote sensing monitor of sandy grasslan d in rergai county by establishing the model of remote sensing image and ground data. Based on the difference of tones and patterns, the image＇ s interpretation and classification index system have been established, the area and distribution and level of sandy grassland have been gained. The research finding gives further technical support to the sandy grassland of Sichuan province. At the same time, the data presents a scientific view for decision controlling grassland desertification.
