摘要： 笔者根据量测1:1×10～5阿克苏河流域土地利用图的实验数据,从量测技术和被测图幅本身特点入手,探讨了它们与精度的关系.图斑面积量测误差主要与图斑的周长/单位面积值有关,并阐述了依其平差的科学性及按图斑面积比例平差的不合理性.

关键词: 量测精度, 误差, 平差

Abstract: The paper study the relations between the accuracy specification and the features of measured map sheet and the measurement skill. It shows that the area measurment error relate compactly with the girth／unit of figures. It not only inter preted the irrationality of the error-distributing according to figures area, but also set forth the rationality of the error-distributing according to girth／unit of figures.
