摘　　要：对土地利用动态遥感监测作业流程与误差来源进行了分析与总结 ,并对图斑面积误差的分布规律进行了探讨 ,通过对遥感监测图斑的三个试验 ,得出变化图斑面积误差服从正态分布 ,即误差均为偶然误差 ,不含有系统误差。本文的分析对今后进一步研究遥感监测误差的性质 ,提高遥感监测精度奠定了基础 ,为遥感监测结果的精度评价提供了理论依据。The operating process and error sources of landuse dynamic monitoring by remote sensing are analyzed and generalized,and the distributing rule of area error is discussed. By three experiments about polygon of remote sensing moniroring ,the conclusion that the error of polygon area follows normal distribution is drawed,that is to say,the error is casual,not systematic.All the work of this article is of benefit to the more researchs of the characters of error and the measures of enhancing the accuracy of dynamic monitoring in times to come,and they give accuracy assessment of remote sensing-derived change detection a science foundation.
