摘　　要：从人眼对于计算机屏幕的最佳分辨率和人眼分辨率与卫星数据分辨率结合影响成图比例尺两个层面入手,从理论角度探讨人眼最佳分辨率、卫星数据分辨率及成图比例尺之间的关系。结果表明:在中高分辨率卫星中,250m分辨率的MODIS卫星最佳成图比例尺为1∶100万,30m分辨率的TM卫星最佳成图比例尺为1∶12万,15m分辨率的ETM卫星最佳成图比例尺为1∶6万,20m分辨率的SPOT卫星最佳成图比例尺为1∶8万,10m分辨率的SPOT卫星最佳成图比例尺为1∶4万,0.5m分辨率的WordView-2卫星的最佳成图比例尺为1∶2 000。This relationship of the best resolution of eye,satellite resolution and mapping scale was studied from theoretical viewpoints started with two levels that the best resolution of eye to computer screen and eye resolu- tion combined with satellite resolution to impact the mapping scale. The results showed that in the medium and high resolution satellite,the MODIS data of 250 m resolution＇s best mapping scale was 1：1 000 000,the TM data of 30 m resolution＇s best mapping scale was 1：120 000,the ETM data of 15 m resolution＇s best mapping scale was 1：60 000,the SPOT data of 20 m resolution＇s best mapping scale was 1：80 000, the SPOT data of 10 m resolution＇s best mapping scale was 1：40 000,the WordView-2 data of 0.5 m resolution＇s best mapping scale was 1：2 000.
