摘要
利用橡胶林第一蓬叶变色-稳定期环境遥感影像作为遥感信息源,根据橡胶林这一时期特有的影像特征,通过监督分类方法实现对西双版纳橡胶种植分布区信息的提取,解决了监督分类时树龄、品种和耕作制度造成的光谱差异问题;监督分类前利用NDVI阈值对非提取目标进行剔除,有效减少了分类数和工作量。分析表明,本次提取精度达到97.6%,较好地反映了西双版纳橡胶种植分布情况,同时对国产卫星的推广应用具有良好的示范作用。
The rubber plantation area in Xishuangbanna was extracted by the supervised classification method from the HJ remote sensing images in the 1 st 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.
