摘　　要：在城镇土地定级方法中引入遥感数据分析,提出了应用遥感数据量化定级因子,实现土地定级快速更新的可行方案。以武汉市为例,利用MODIS植被指数和陆表温度产品,准确量化环境因子对定级单元的作用,快速更新武汉市土地定级成果,缩短了更新时间,提高了工作效率,优化了更新成果。Urban land grading is very important in land management and pricing and is also time -consuming and expensive. In this paper, remote sensing observations were employed in the land grading system for updating land grading results timely and accurately. MODIS NDVI and LST images of Wuhan City were used as surface grading factors and applied to a quantitative evaluation of the living environment of Wuhan. Compared with traditional methods, the remote sensing analysis has the merit that the land grading results of Wuhan City can be conveniently updated with a shorter time, higher efficiency and more accurate results.
