| Abstract: | Information of cultivation land area and cereal crops output is an important basis for the national food policy and the development of economic planning.In this paper,taking Xiyang as study case,TM data was used,land use map of the study area combined,and spectral information based,cultivated and non-cultivated land information was extracted.Finally,by maximum likelihood supervised classification,cultivation land area is 29 242.1 hm2 and its classification accuracy is as high as 93.3%. |
