In this paper, we studied the spectralcharacter of our study region in detail and based our classification system on the spectralcharacter and our filed work.
仔细分析了研究区典型地物的光谱特征和同物异谱与异物同谱现象，并结合实地考察建立了分类体系。

Compared with the classification method purely based on spectralcharacter, this method can improve the classification accuracy and refine object classes in some extent.
与单纯基于光谱特征的分类方法进行比较，该方法在一定程度上改善了分类精度，细化了地物类别。
