| 以安徽省全椒县、长丰县和五河县为研究对象，监测其补充耕地土壤肥力和健康状况，进行耕地质量等级与农业生产基本条件符合性调查与评价。结果表明，全椒县、长丰县和五河县2020年补充耕地平均耕地质量等级分别为5198、4.811和3.911；补充耕地平均耕地质量等级总体上低于县域水平；补充耕地质量等级面积分布总体上比县域水平分布更分散；乡镇补充耕地质量等级与全镇耕地质量等级存在正相关关系，与乡镇补充耕地面积存在负相关关系；补充耕地土壤速效钾和pH平均值高于县域土壤平均值，有效磷平均值低于县域平均值，有机质平均值与县域平均值变化差异较大。 |

| Taking Quanjiao County, Changfeng County and Wuhe County in Anhui Province as the research objects, the soil fertility and health status of supplementary cultivated land were monitored, and the conformity of cultivated land quality grade with basic conditions of agricultural production was investigated and evaluated. The results showed that the average quality grade of supplemented cultivated land in Quanjiao County, Changfeng County and Wuhe County in 2020 was 5.198, 4.811 and 3.911 respectively. In pilot counties, the average quality grade of supplemented cultivated land was generally lower than the average of all cultivated land. The distribution of supplemented cultivated land quality grade area was more dispersed than that of all cultivated land quality grade area. The quality grade of supplementary cultivated land was positively correlated with that of all cultivated land, and negatively correlated with the area of supplementary cultivated land. The average of available potassium and pH value in soil of supplemented cultivated land was higher than the average of all cultivated land, the average of available phosphorus was lower than the average of all cultivated land, and the average of organic matter was significantly different from the average of all cultivated land. |
