摘　　要：以顺昌县为研究区域,探讨利用遥感影像提取我国南方地区竹资源专题信息的技术。通过分析竹资源与其它林地在TM影像上的光谱特征差异,采用最大似然法和叠加、掩膜等处理方法,实现提取竹资源专题信息的光谱片层分割。在此基础上,基于灰度共生矩阵,分析竹资源与其它林地的纹理特征差异,提出"基于光谱片层—面向纹理类"的竹资源专题信息提取技术。研究结果表明,采用该技术,竹资源专题信息提取精度可达84.8%,在我国南方地区具有较好的可行性和优越性。Taking Shunchang County as the research region, the technology of bamboo resources thematic information extraction from the remote sensing images in the South of China is studied and discussed. Using maximum likelihood and the technology of stack and mask, the spectrum film was carved up according to the analysis for the spectrum difference between bamboo resources and other forest lands. Afterwards, the texture difference was analyzed and the bamboo resources thematic information extraction technology, based on the spectrum film-Texture oriented was put forward on the basis of Gray Level Co-occurrence Matrix. The result shows that the extraction overall accuracy could reach 84.8G with the help of the technology and it is of good feasibility and superiority in the south of China.
