For more than ten years, the demonstration center took the space remote sensing system as the research object,and systematically carried out the application-oriented space remote sensing scientific demonstration concepts, theory methods, technology engineering and application research. This paper is a systemic summary of the Demonstration Center team in space remote sensing scientific demonstration research and practice for a long time, which mainly introduces the content of four aspects, i.e. the preliminary cognition of scientific demonstration, the issue concerned to remote sensing demonstration, the theoretical system and model method set of remote sensing demonstration, and remote sensing demonstration practice of the application-oriented space remote sensing system. In this paper,a scientific demonstration definition of application-oriented space remote sensing is givenfor the first time and the range and content of demonstration is also detailed analyzed, and a 3D spatial structure of remote sensing demonstration scope composed of knowledge dimension, process dimension and logic dimension is proposed synchronously. As the social development has increasingly accelerated and the informatization level has increasingly enhanced, the whole space remote sensing data information chain is driven to develop towards larger-scale data stream, shorter response time cycle, more comprehensive data integration and higher data quality, so that the space remote sensing system will step in a development phase of new "intelligent remote sensing". Owe to the rapid development of our civil space in the past ten years,we have the opportunity to participate in the FY-3 satellite flying evaluation, multi-angle polarization multispectral remote sensing sensor demonstration, and HJ satellite applicationengineering demonstration, and have made the breakthrough invarioustheory methods. These research result have been applied to several demonstrations, such asthe2030 civil space development planning, the high resolution earth observation system, the national natural disaster spatial information infrastructure, the medium and long-term development of national civil space infrastructure, the China earth observation system planning（2030） and so on. Meanwhile, the theory system of remote sensingdemonstration has been established, which includes the information flow model, information feature model, information application model, information quantity analysis model, data engineering modelsystem structure model, system state magic model, system quality model, dynamic model of system development and system model of system capability. The theoretical system for remote sensing demonstration and corresponding model method set gradually formed through practice will comprehensively reflect the structure, state and development state of the space remote sensing system, and will be used for conducting investigation, analysis, evaluation, forecast, and carrying out practical exploration on the space remote sensing system. 航天遥感系统 遥感论证 信息流 智慧遥感 space remote sensing system remote sensing demonstration information flow intelligence remote sensing V443.5 民用航天预研项目我国卫星遥感应用需求和载荷指标综合论证;地球表层系统科学研究应用示范系统（一期）高分重大专项（编号:Y4D00100GF）;基础信息产品生产算法集成研究高分重大专项（编号:Y4D0100038）;中国科学院战略先导专项（编号:Y1Y02230XD）~~ 2021-06-09 5 20
