我国正处于城镇建设的高速发展阶段，城市用地现状信息提取是进行城市精细化管理的重要基础工作。本文通过对高分辨率遥感影像光谱特性的深入分析，提出一种结合面向对象分类和GIS分析技术的城市用地现状分类的处理新模式，实现了城市用地现状的高效分类。利用高分一号卫星高分辨率遥感数据进行验证，总体分类精度达81．44％。试验表明，该处理模式有效地简化了人工操作步骤，大幅度提高了高分辨率遥感影像城市用地现状提取的效率。

Our country is in a stage of rapid development of city construction, and urban land information extraction is an important basis for the city fine management work.Based on the analysis of the spectral characteristics of the image, this paper proposes a new model for urban land use classification by combing object-oriented classification and GIS analysis techniques.By the experimental verification of GF-1 satellite remote sensing images, the overall classification accuracy reaches 81.44%.The proposed method can greatly simplify the manual operation and improve the efficiency of manual interpretation.
