| 摘 要： | 以案例的形式分析如何应用灰色关联度法进行耕地定级评价。结果表明,研究区丰顺县耕地质量总体一般,质量最优的1级耕地以及较次之的2、3、4级耕地质量面积依次占全县耕地总面积的17.06%、39.11%、31.62%、12.21%。同时,应用层次聚类法对耕地定级划分结果的合理性进行了检验,检验结果显示全县耕地面积和耕地定级评价单元数划分的正确率分别达到87.68%、87.17%。

| Abstract: | The study analyses how to apply grey correlation to carry out grading evaluation of farmland in the form of case.The results showed that the total quality of farmland was general in Fengshun County,and its grades of quality from high to low were 1,2,3 and 4 which area ratio was 17.06%,39.11%,31.62%,12.21%,respectively.Meanwhile,the rationality of farmland grading division result was tested by using hierarchical cluster method,the test result showed that the correct rates of the whole county's farmland area and grading evaluation unit numbers were 87.68% and 87.17%,respectively. |
