摘  要：
目前我国基本上采用因素法进行农用地定级,而作为重要方法之一的修正法则应用很少。本文以宜兴市为例,对修正法农用地定级技术路线、指标控制区划分、单元划分、修正因素选取和量化、定级指数计算、级别划分的方法和改进进行探讨,并与因素法比较。结果表明:修正法和因素法的方法原理大致相似,但修正法在分等基础上进行,是对分等结果的细化和深化,可大大缩减工作量,而且其定级结果具有很好的横向可比性。

摘  要：
Currently, the factor method is usually used to grade agriculture land, however, the modification method, as an important means, is rarely used. Based on Yixing as a case study, processes of agricultural land gradation using the modification method, including technical route, partition of index control section and gradation units, selection and quantification of factors to be modified, computation of gradation index values, grading and improvement, were discussed. Comparison with the factor method was also done. Results indicate that the modification method is consistent with the factor method in terms of principle, but the modification method is based on results of agriculture land classification, making them more detailed and smaller in units. As a result, the modification method can not only save workload but also make results of the land gradation more comparable transversely.
