This paper takes the agricultural base of Shenyang Military Regions in north-east as an example, synthetically analysizing the current situation and development potential of crops on the basis of fertility, seeded area, crop yields of different fields, design and realize the thematic system based on component GIS, realize the variable-rate production of different fields, contains the practical value in variable-rate production mode and implement of precision agriculture.
