摘　　要：针对手机GIS在农业信息化应用中的空间位置误差,通过定性和定量分析,确定误差来源,计算误差大小。经过分析和计算,认为误差主要来源于两个方面——手机定位误差和坐标系转换误差。其中手机定位是误差主要源头;在小尺度范围内,对数据经过合理处理后可以将误差控制在5 m左右,符合农业信息化应用对精度的要求。最后根据误差的来源和大小,提出了合理的建议和方法来减小误差,提高应用精度,为普及手机GIS在农业信息化应用中提供依据和参考,以促进农业信息化进程。In view of the spatial position error in the application of mobile phone GIS to agriculture informatization,the sources and magnitude of the errors were determined and measured through qualitative and quantitative analysis.It was concluded that the errors mainly come from the mobile phone positioning and coordinate conversion,and the mobile phone positioning is the major source;within a small scale,the error can be controlled within 5 m after reasonable data processing,which meets the requirements of agricultural informatization for precision.According to the sources and magnitude of errors,some suggestions and methods were proposed to reduce the error and improve the application precision,so as to provide references for the application of mobile phone GIS and accelerate the process of agricultural informatization.
