Cultivated land quality update is to mainly reassign value and calculate grade of the changed cultivated land quality. The update of the cultivated land quality in land remediation project areas was discussed in this paper according to the regulations of farmland classification and through the study on the quality change of the cultivated land, which is not only to correct the grading factors, but also to amend the land utilization and economic coefficient of cultivated land according to the of practical production of cultivated land after land remediation. The results showed that the physical quality increased by 0.53 to 0.89 in the selected 9 samples; utilization quality and economic quality increased more apparently, the utilization quality of the 8th sample raised 1.07 and economic quality was 1.12, the 3th sample had the least promotion but its utilization quality and economic quality also raised 0.61 and 0.49, respcectivly, reflecting the promotion effect of land consolidation on farmland quality.
