中文摘要：
通过对常用高分辨率影像的参数、软件及特征指标等进行系统总结和整理,分析了梯田信息提取技术的特点和难点,并将目视解译法、基于象元提取法和面向对象提取法提取梯田信息的效率、精度、优缺点进行了比较。面向对象法提取效率和精度都较高,因此是目前高分辨率影像分类提取的发展趋势。
英文摘要：
This paper systemically reviewed the parameters,software and characteristic indexes of typical high resolution images based on va-rious methods and analyzed the technical characteristics and difficulties of terrace＇s extraction. It dissected visual interpretation method,pixel extraction method and object-oriented extraction method and compared the efficiency,precision,advantages and disadvantages of these three kinds of extraction methods. The efficiency and precision of object-oriented extraction method are both higher,so it is the trend of high-reso-lution remote sensing image used in the terraces-extraction technology.
