Abstract :
It is very meaningful to accurately master land use status and its change at county level. In the light of a key project of “the Ninth Five-Year Plan (China)”, the integration theory and implementation methods of remote sensing, Global Positioning System and geographical information system that are used in dynamic monitoring of land use at county level are introduced. Results indicated that 96.2% of the target regions of land use change were found by RS. The data-acquiring methods, “pseudo 54” algorithm and “2D abnormal data” processing method can effectively prompt the efficiency of both field and laboratory work and improve data precision. Contrasted with traditional investigation method of land use change, the 3S system brings a qualitative-economic benefit by over 20 times. Finally, some conclusions are reached
