基于农用地分等的重庆市耕地产能核算的宏观检验研究

为验证耕地产能核算结果的科学合理性，进一步完善现行的《农用地产能核算技术规范》，依据县域内平均海拔数据和粮食产量数据，采用文献资料法、比较分析法，回归分析法，在对重庆市农用地分等以及耕地产能核算结果进行分析的基础上，对重庆市耕地产能核算结果进行宏观检验分析与评价。结果表明，域粮食总产——理论、可实现、实际产能模型有着显著的线性回归关系；从回归系数来看，实际产能与粮食产量更接近，其次是可实现产能，最后是理论产量；县域平均海拔与平均海拔——理论、可实现、实际单产3个层次单产之间有显著的线性回归关系，其中，理论单产、可实现单产、实际单产都受海拔因素影响，3个层次单产符合实际。

Study on Macroscopic Examination of the Cultivated Land Productivity Calculation in Chongqing Based on Farmland Classification

To verify the scientific rationality of the results of cultivated land productivity calculation,and in order to further improve the existing technical specification of agricultural productivity calculation,based on average elevation data and grain yield data within the county,the literature material method,the method of comparative analysis,the method of regression analysis were adopted.Based on the analysis of the results of cultivated land productivity calculation and farmland classification in Chongqing,...
