摘要
研究目的:分析农用地质量与粮食生产能力之间的关系。研究方法:主要应用样点的标准粮产量与土地利用等别指数进行回归分析,根据回归分析所得的线性关系推算出3省的粮食总产量。研究结论:通过农用地分等成果进行产能核算具有一定的科学性,可在已经进行农用地分等的省份进行推广应用。
Study objective：For analyzed the relationship between agricultural land quality and food production. Study method： Doing regression analysis of grain yield of the samples and land-use index and calculating the grain yield of the three provinces according to the linear relationship. Study conclusion：It was of certain scientific to calculate the yield potentiality by the result of agricultural land classification, and extended study could be spread in other provinces where agricultural land classification had already been done.
