摘　　要：本文基于Landsat TM遥感影像数据和面向对象的分类方法,对比分析特征向量相关系数法和向量相似度法应用于变化检测的效果,结合两种方法对福建省长汀县土地覆被进行变化检测,并对结果进行精度评价和植被演替趋势分析。结果表明,利用相关系数法和向量相似度法变化检测的总体精度在85%以上,可以有效进行大范围的变化检测和植被演替趋势的监测。Based on Landset TM data and object-oriented method, the research compared the change detection effects between the correlation coefficient method and similarity vector method, combined the two methods to detect the land cover change in Changting County, and analyzed the assessment result to give the trend of vegetation succession. The result showed that the overall accuracy surpassed 85 % based on TM data with combination of the two methods which could be used to monitor the land cover and the trend of vegetation succession effectively in large area.
