摘　　要：阐述了线性光谱混合模型及其在遥感专题信息提取方面的优势,并以枇杷重要产地莆田市常太镇为对象,选用ETM卫星影像,利用线性光谱混合模型提取枇杷树信息,绘出枇杷树的丰度图,据此估计出枇杷的种植面积,最后对提取结果进行了验证,实验证明了该方法提取枇杷树信息的有效性。It is very important and difficult to extract thematic information using remote sensing data. Firstly, This paper introduced the concept of linear spectral mixing model and their resolution method is introduced. Then, taking Changtai town in Putian as research region, this approach was used to extract loquat thematic information from ETM data. The bundant degree plots resulting from experimental data could calculate the loquat＇s plants area, The results of the experiment showed that this approach is effective in extracting loquat thematic information.
