This paper briefly introduces the application of remote sensing and geographic information system in environment comprehensive evaluation of Shenfu-Dongsheng area. According to the characteristics of the environment in this area, a comprehensive environmental assessment system based on remote sensing information was established. The system includes 10 factors including environmental pressure load, environmental problems and environmental potential. The analytic hierarchy process combined with expert knowledge has realized the weight ranking of all factors. Taking GIS as the technical support, the paper analyzed the spatiotemporal change of each subject and established the comprehensive evaluation model of environmental quality. Detailed and objective evaluation of the quality of the area’s environment
