摘  要:目前中国耕地质量保护和管理技术支撑体系中的等别评价方法和成果仅能反映耕地质量宏观层面的差异,缺少反映耕地质量微观差异的评价方法与成果,无法满足耕地质量保护和管理的需要。研究探索以耕地分等成果为基础,增加能反映耕地质量微观差异的评价因素,采用利用等指数与新增定级因素加权计算定级指数并划分级别;通过对河南省65个县(市)的耕地质量定级指数的统计分析,显示级别与利用等别具有较高的关联性,二者具有较明确的对应关系,体现了加权修正的特点,确保了级别在全省范围内具有可比性;同时,级别显现了耕地质量的微观差异,与等别的宏观性构成互补,完善了耕地质量保护成果体系,可为耕地质量保护和管理提供更科学合理的技术支撑。The equalization evaluation methods and results in the technical support system of cultivated land quality protection and management in China can only reflect the differences of cultivated land quality at the macro level,but not at the microscopic level.Therefore,the technical support system can not meet the needs of farmland quality protection and management.Based on the achievements of cultivated land classification,the evaluation factors that could reflect the microscopic differences of cultivated land quality were added,the weighted caculation of the grading index was performed and the grade of cultivated land was carried out by index of usage classification and new grading factors.Through the statistical analysis of the grading index of cultivated land quality in 65 counties(cities)in Henan Province,it was shown that there was a high correlation between the grade and the usage classification,and the two had a relatively clear corresponding relationship,reflecting the characteristics of weighted correction,and ensuring that the level was comparable across the province.At the same time,the grades showed the microscopic differences in the quality of cultivated land,which complemented the macroscopic composition of the grade,improved the system of cultivated land quality protection results,and could provide more scientific and reasonable technical support for cultivated land quality protection and management.
