摘　　要：对基于SPOT5遥感影像的土地利用更新调查成果及原土地详查成果进行了点位误差分析,同时以浙江省绍兴市杨汛桥镇、湖州市南浔镇为例,利用SPOT5数据进行了1∶10 000土地利用现状更新,对更新成果和原土地利用详查的点位精度进行了分析和比较.结果显示,基于SPOT5影像的土地利用更新调查数据的点位精度为:X方向中误差5.2 m,Y方向中误差3.8 m,点位平面中误差6.5 m;而原详查数据精度基本为:X方向中误差11.6 m,Y方向中误差11.5 m,点位平面中误差16.4 m.Data error of land use change surveying based on SPOT5 remote sensed image was compared with that of detailed land survey in theory. Two cases studies were taken in Nanxun town of Huzhou city and Yangxunqiao town of Shaoxing city in Zhejiang province. The errors of the two kinds of data obtained from the different investigation methods at 1 ： 10 000 scale were compared and analyzed with antitheses. The results from the study showed that： Mx=5.2 m, My=3.8 m, May=6.5 m were the data errors for the SPOT5 remote sensing image-based land use change surveying. Mx=11.6 m, My=11. 5 m, Mxv=16. 4 m were the data errors for detailed land survey.
