Abstract: The rubber plantation area in Xishuangbanna was extracted by the supervised classification method from the HJ remote sensing images in the 1st leafumbrella of rubber tree color to stable stage with specific spectral features.This method solved the spectral differences problem of supervised classification caused by age,species and farming.The non extractive features ware removed before supervised classification which effectively reduced the number of categories and workload.Analysis showed that the classification accuracy was up to 97.6% which reflected preferably rubber cultivation distribution in Xishuangbanna.It was a good model for the promotion and application of domestic satellite.
