| Abstract: | With the support of GIS technology,an analysis of land use,slop,temperature,precipitation and districtsof Qingchuan county,Sichuan province has been made. The result shows all the dry land returned to forest or grass land of the studying area is 23571 hm2.that is 37.4% of the total area of Qingchuan′s farm land and 8.1%of Qingchuan lande area.Those type of land widely spread in all 31 towns of the county and relatively concentrate in Dayuan,Qingxi,Qima,Suhe and Liangshui.
