摘要："Beijing 1" is one Micro-satellite of the international Disaster Monitoring Constellation (DMC). It was launched successfully in 2005, and has high-powered characteristic, such as high gaining data ability, high storage ability, high space resolution, high time resolution and low cost. At present it is necessary to make objective appraisal for image quality and application potential in different research field in order to provide beneficial reference for the satellite future design and application. In China, LUCC space-time database construction is one important domain in remote sensing technology application field, and mainly relied on foreign commercial satellite. Now "Beijing 1" Micro-satellite Image can be one kind of new data source. This paper taking LUCC as the application object, Researched on "Beijing 1" Micro-satellite multi-spectra Image Quality and Land Use Classification Precision. The main content and research method in the paper as followed: Image quality was studied through analyzing visual quality, spectrum characteristic and geometry correction precision. land use classification precision was studied through selecting characteristic variable, optimizing training sample and establishing classification template, constructing three different methods "Maximum Likelihood, Minimum Distance and Mahalanobis Distance" to make land use classification and appraise the classification precision. The research results show that: "Beijing 1" image has rich spectrum information, clear texture structure and good geometry performance. Image quality is fine and land use classification precision is high. Image can satisfy medium scale map request, can be widespread used in land use field and become the main data source that remote sensing data renews in land use research
