| 摘 要： | 在江苏省农用地分等的实践基础上,以无锡市为例,对农用地分等中各修正系数进行相关分析与贡献率分析,指出经济系数直接参与分等指数修正的不合理性,提出了引入经济影响度对经济系数量化进行改进的方法,并对不同方法得出的农用地分等结果进行了比较。

| Abstract: | Based on the practice of farmland classification in Jiangsu Province, Wuxi was taken for a case study to perform correlation analysis and contribution rate analysis of amended coefficients of farmland classification, which revealed the irrationality of direct employment of economic coefficient in amending classification indexes. Then a modified method was proposed, introducing economic influence degree into economic coefficient quantification, and the results of farmland classification in Wuxi City with different methods were compared. |
