摘要
简要介绍了农用地产能层次划分和核算的基本原理；以柳州市区农用地产能核算项目数据为例，重点分析了可实现产量的数据收集过程和误差来源，运用标准差变换手段对外业数据进行分析处理，详细验证了处理前后数据分布和变化的情况，并对异常数据溯源，简要说明其产生的原因。
Abstract
The basic principles of farmland productivity calculation and its levels division were introduced briefly.Based on the project data of farmland productive calculation in Liuzhou City, the collection procedure of production achievable data and related error source were analyzed slectively.Standard deviation was applied on the field data processing, and the data distribution and variation of pre-processing and post-process-ing were also verified in details.The reason of anomaly data was explained by tracing back to the source.
