| 摘 要： | 以Landsat 8影像为数据源,在综合分析典型地物光谱、纹理和空间分布等特征的基础上,利用归一化湿度指数(NDMI)、纹理、地形等多源数据,构建了基于决策树规则的西双版纳森林覆盖信息提取模型。验证结果表明,该模型的总体精度达99.08%,与传统的监督分类相比(96.08%)提高了3个百分点。

| Abstract: | Taking Landsat8 image,normalized humidity index （NDMI）,textures,terrain and other multi-source as a data source,and based on a comprehensive analysis of a typical feature spectrum,texture and spatial distribution characteristics,information extraction model based on decision tree rules for Xishuangbanna forest coverage has been made.Verification results show that the overall accuracy of the model is up to 99.08％,compared with the traditional supervised classification model （96.08％）,the accuracy is improved three percentage points. |
