【摘要】 本文从统计学的角度阐明了回归分析的原理, 并以广东省A市为例, 论述了回归分析在农用地分等中的应用。通过对自然质量等指数、利用等指数及其所对应的实际标准粮产量进行回归分析, 结果表明后者与实际标准粮产量的拟合优度大于前者, 即对自然质量等指数进行利用程度修正后, 利用等指数更接近于实际标准粮产量, 并据此提出了农用地在利用过程存在的问题及改进的对策。更多还原

【Abstract】 The authors clarify the principles of regression analysis through statistics, and take City A of Guangdong Province for a case study. They discuss the application of regression analysis in farmland classification. According to the regression analysis of the index of natural quality, land use and the corresponding actual standard food output , it is obvious that the latter is superior to the former, namely after the correctness of utilization degree of natural quality, the index of land use approaches remarkably the actual standard food output.The problems and countermeasures in the process of farmland utilization have also been discussed.更多还原
