Analyzing implementing coordination and its spatial pattern of farmland consolidation in China synthetically is of great theoretical and practical value for improving land consolidation scientific decision-making. Based on the data acquired from the dataset of consolidation project management during 2006-2012, this paper analyzes the implementation status of farmland consolidation at county level by three core indices i.e., the intensity, the potential and the difficulty of farmland consolidation. Then mechanical balance model is used to build a comprehensive method for evaluating implementation coordination of farmland consolidation in China. Finally combined with the geographical spatial statistical methods, we make a quantitative analysis macroscopically on the implementation coordination of farmland consolidation in China during 2006-2012. The conclusions can be summarized as follows: (1) regions with high consolidation intensity are some traditional agricultural areas in China, high consolidation potential mainly located in semi-humid and semi-arid region, and high consolidation difficulty distributed in complex terrain region or eastern developed areas; (2) the national average of coordination variable Ftotal is 1.33, and all coordination categories have no significant difference on quantity proportion, which indicates the general coordination of farmland consolidation is in the antagonism states and its implementation is still not prominent. Implementation skewness θ is distributed in the I~VI quadrants, in the majority with transitional quadrants (II and V), and collaborative characteristic overall performance for mismatching among the intensity and potential of regional consolidation; (3) coordination variable is significant agglomeration and spatial correlation nationwide. Coupling coordination variable Ftotal and implementation skewness θ, we identify 6 categories of problem areas mainly located in northwest China, Yangtze River Delta and Pearl River Delta, where implementation status of farmland consolidation is urgent to be optimized. Aiming at the existing problem of farmland consolidation implementation, our findings suggest that differential consolidation strategy and mechanism innovation according to planning requirements should be made to further optimize the project schedule, also in view of regional natural resource conditions and socio-economic status.
