%X The extraction of cultivated area has great practical and research significance.In this paper,a method of the scale transformation to extract farmland by using different pixel size satellite remote images is presented.Take the northern of Jiangsu plain for example,the proportion coefficient between the cultivated area in three scales,which is MODIS(250 m) image,CCD(19.5 m)and HR (2.36 m) of CBERS-02B,that is computed by sampling statistics method to increase the area accuracy.The coefficient of sample areas in this paper between MODIS images and truly area is 41.7%.At last the farmland area of MODIS image is calculated in this method and compared with the normal result.The experimental result indicated that this method has the good operationality and raise the accuracy,that may carry on the large range cultivated area the extraction.
