Abstract: Abstract: Successful launch of the Landsat-8 satellite provides important new data source for agricultural remote sensing. Taking Yucheng County as the study area, to explore winter wheat planting area estimation method at county level based on Landsat-8 imagery. In order to expand the differences of spectrum feature between winter wheat and other surface features, select the imagery when winter wheat up growing season. According the spectral features differences between kinds of surface features to construct decision tree model of extraction winter wheat planting area. The results showed that: the extraction accuracy was 96.30% using of the original imagery of 30 m spatial resolution , the extraction accuracy was 99.17% using of the fusion imagery of 15 m spatial resolution, this method can provide technical support for the county's winter wheat area extraction.
