Because of the influences of economical construction development and natural factors, the change of land use condition and crop distribution has been taking place every year, including the decrement of cultivated land, the adjustment of crop distribution and the increment of building-used land. In order to capture the dynamic change of land use and crop distribution Promptly, at the request of National Agricultural Zoning Committee, we made a study test for dynamic monitoring in Beijing area, using TM imagery integra- ted with the color infrared aerial photo and maps. When the precise geometric rectification of TM imagery was made with the ground control points selected from topographic map in scale of 1:100000, the accuracy of half a pixel is high. In the comparison analysis between the multi-factor auto-classification on microcomputer and visual interpretation, both qualitative accuracy can reach to 94 percent. The multispectral information of TM imagery is abundant, both its positioning and qualitative accuracy are relatively high, so it it suitable for the dynamic monitoring of land use and crop distribution, and will has shot period and high efficiency.
