Abstract Land consolidation is an effective measure to improve land use conditions and land quality, and hence the evaluation of the land quality after land consolidation constitutes one of the important tasks. In this paper, based on the connotation of cultivated land quality and basic requirement of land consolidation project, the authors selected two fundamental factors of the natural conditions and cultivated land use conditions as well as 12 impact factors and used the Delphi method and analytic hierarchy process to determine the weights and construct a cultivated land quality evaluation index system based on the land consolidation. Then, taking land consolidation project of Hanshan County in Anhui Province as a case study, the authors employed the traditional soil survey in combination with the 3S method to analyze the land quality temporal pattern changes during the land consolidation, thus obtaining the level changes before and after the land consolidation. The study result shows that the levels and spatial distribution of land quality of the study area experienced considerable changes through land consolidation. Compared with the situation before land consolidation, the percentage of level 1, level 2 and level 3 increases by 7.20%, 11.95% and 0.65% respectively, whereas the percentage of level 4 and level 5 is reduced by 15.65% and 4.16% respectively. After the land consolidation, the overall level of cultivated land quality is 1.291 times that of the level before the land consolidation.
