摘要
研究目的:研究产能核算基础数据的调查和处理方法。研究方法:区试产量替代法,分层抽样法,年鉴调查法,残差分析法和空间滑动平均法。研究结果:(1)理论产能、可实现产能和实际产能因样本本身特点不同,样本的调查方法也各不相同;(2)通过残差分析法和空间滑动平均法处理之后,数据的整体和局部异常值被剔除或修正,数据质量得以保证。研究结论:本文可为今后其他省份开展工作提供借鉴。
The purpose of this paper is to study the methods for data survey and processing in calculating the productivity of agricultural land. Methods of substitution of regional productivity, stratified sampling, statistical data analyzing, residual analysis and spatial-moved averaging were employed. The results indicate that： （1） the data survey methods for calculating theoretical, realizable and actual productivity of agricultural land samples are different according to their different characteristics; （2） total and partial abnormal values of data can be removed or corrected by residual analysis and spatial-moved averaging so as to guarantee the quality of the data. It is conduded that the paper can provide reference for carrying out similar works in other provinces in China.
