摘　　要：地表覆盖分类数据是地理国(省)情普查成果数据的重要内容,文章以基于中分辨率遥感影像生产的四川省2000、2010和2014年3期地表覆盖分类数据为例,通过自行制定的一套行之有效的质量评定方法,实现了对基于中分辨率遥感影像获取的地表覆盖分类数据成果的精度评定,结果表明,3期地表覆盖分类数据精度均满足设计要求。The surface cover classification data is an important part of the geography （province） situation monitoring data. Based on the surface cover classification data derive of the remote sensing image of Sichuan Province in 2000a, 2010a and 2014a, the paper achieves the accuracy assessment of the results of surface cover classification data based on medium resolution remote sensing image acquisition through the development of a set of effective quality assessment methods. The results show that the accuracy of the surface cover classification data meets the design requirements.
