摘要
本文介绍一种以ＴＭ遥感图像光谱分类为基础，专家知识为依据，应用地理信息系统提取各种辅助信息，以图斑作为基本分类单元，按照一定的专家系统推理机制，对光谱分类中精度低的地类作进一步判别，达到提高分类精度的方法。通过对山西省隰县的应用，取得了较为理想的效果。
Based on the expert system,taking the remote sensing spetrum classification as the basis and using the geography information system to draw various kinds of supplementary information,an applied study was made.Taking the segments as basic classification unit,further judgement was made for the categories of the spectrum classification with lower precision.This classification would be reclassified to raise its accuracy.The result shows it is an effective method in Xi County of Shanxi Province for the protection forest of Loess Plateau.
