基于决策树的荒漠化遥感分类技术

Decision Tree-Based Remote Sensing Classification Technique of Desertification

阜新地区属于农牧交错带,是土地荒漠化类型齐全、结构复杂的典型区域。文中以遥感(RS)作为荒漠化信息获取与分析的工具,利用基于决策树的分析方法,结合区域环境特点,根据不同的荒漠化类型的遥感影像特点,针对荒漠化类型、强度进行了分层次提取和分类。

The Fuxin region in Liaoning Province is a halved belt of agriculture and animal husbandry and also is a typical area with its desertification be com plete in type and complicated in structure. In the paper, in view of environmen tal characteristics of the region and features of remote sensing images of vario us types of desertification, the desertification is collected by layer and class ified according to different types and intensities with the decision tree-based analysis method and by using the RS technique as a tool to acquire and analyze i nformation of the desertification.
