| 摘 要： | 针对大规模、复杂的地类环境下,土地利用分类快速提取改进传统单一监督分类方法精度低等不足,以大连市部分区域作为研究区,采用"分区处理"方法进行研究,并用内部与外部精度评价方法进行精度评价。研究结果表明:"分区处理"方法精度明显优于单一监督分类方法的精度,并且能快速分类,提高工作效率,对合理开发土地资源政策的制定有一定的辅助意义。

| Abstract: | In order to quickly extract the classes for land use with complex and large-scale environment and change the low accuracy weakness of the single supervised classification, the author chose a part of Dalian city as a research area. Through searching for the"Zonal dispose"method .And the precision assessment of the results was expected to use the internal precision and external accuracy. The following conclusions are shown: the accuracy of the"Zonal dispose"is higher than the accuracy of the single supervised classification. Comparative analysis on the results derived from the traditional visual interpreting ,it can quickly extract and improve work efficiency. |
