Abstract: This study focused on the dynamic state of farmland quality of Yucheng County in the North China Plain, in order to provide experiences for farmland utilization and sustainable agricultural development in plain areas. Based on sampling, observation and statistics data, the subordinate functions, the principal component analysis (PCA) method and the composite index evaluation model were selected to perform a dynamic evaluation of farmland quality of Yucheng County in 2001 and 2009. The results revealed that, the natural, ecological and economic quality of farmland in Yucheng County in 2001 were dominated by the first, second, third, fourth grade; the second, third, fourth grade and the third, fourth, fifth grade, respectively. The first and second grade of farmland in 2009 increased dramatically in comparing with that in 2001. The distributions of farmland quality grade in both 2001 and 2009 were similar. From 2001 to 2009, the projects like “testing soil for formulated fertilization” and “ecological agriculture park” promoted the substantial conversion of farmland quality from third and fourth grade to first and second grade in the study area, and the grade promotion had obvious regional difference. The dynamic evaluation of farmland quality based on multi-source data with comprehensive index model method developed in this study could comprehensively reflect the overall dynamic change characteristics and spatial heterogeneity of the natural, ecological and economic quality of farmland.
