[Objective] The objective of this study was to provide the scientific and reliable basis for the sustainable management, by studying on application of remote sensing technology advanced technology in Arid River Valley in Sichuan province. [Method] Remote sensing with Arid River Valley area data was used to research the area of Arid River Valley in Sichuan province. Moreover, it initially got Sichuan Arid River Valley area, and determined the area of the Arid River Valley. [Results] The results indicated that the extent of arid dry valley distribution was huge with total area of 10 955.2 km. , and proved that the arid dry valley area distribute in the west and south Sichuan province in the upper reaches of Yangtze river. The accuracy of using remote sensing was up to requirement as high as 95%. [Conclusion] This paper will provided a scientific basis for its future develop-changing research and controlling utilization measures.
