摘　　要：针对土地勘测定界数据构建中最新年度变更调查数据至第二次全国土地调查(以下简称“二调”)数据逐年追溯计算会产生面积误差的问题,本文总结了利用Excel数据透视表,基于要取舍小数位的下一位数值较小不做取舍的原则,综合考虑各权属下各地类面积取舍后的总和与未取舍的总和之间的差值、要修改的地类面积值在本权属中面积值的占比情况,选定要修改权属下的地类面积值的数据强制配平规则。该方法在实际项目中得到了广泛应用,其成果数据精准合理,为更好地服务自然资源行政主管部门的用地审批工作提供了良好的数据支撑。The calculation of the latest annual change survey data being traced back to the data from the second national land survey(hereinafter referred to as the"second survey")during the construction process of land surveying and demarcation vector data usually causes area error.This paper summarized the use of Excel pivot tables and followed the principle that data with smaller values in the next digit of the rounding decimal are not rounded off.It took into account the difference between the total area of each land category under each jurisdiction after rounding and the total area that has not been rounded,as well as the proportion of the area value of the land category to be modified in this jurisdiction,to select the forced data trimming rule for the area value of the land category under each jurisdiction to be modified.This method has been widely applied in practical projects,and its results are more accurate and reasonable,providing good data support for better serving the land use approval work of natural resources administrative authorities.
