摘  要:
运用耕地质量定级评价工作中常用的因素法及修正法对田林县耕地进行耕地质量评价,对两种评价方法的结果进行比较分析、相关性分析,并与国家利用等别进行比较分析。结果表明,修正法在初步确定耕地质量级别时,在国家级利用等指数的基础上考虑了各级耕地之间的渐变过渡,未产生跳级现象,与国家利用等有着较好的衔接;修正法平均等别的线性斜率高于因素法,定级结果区分度较好,定级结果相较因素法可靠度更高。

摘  要:
The cultivated land quality evaluation in Tianlin County was carried out by applying the commonly used factor method and amendment method in the grading evaluation of cultivated land quality. The results of the two evaluation methods were compared and analyzed, correlation analysis, and comparison with national utilization. The result showed that: When the revised method initially determines the quality level of cultivated land, it considers the gradual transition between cultivated land at all levels on the basis of national-level utilization index, and does not produce jumping phenomenon, and has better performance with national utilization; the average slope of the correction method is higher than the factor method, the classification result is better, and the grading result is more reliable than the factor method.
