Farmland consolidation is the focus of land consolidation in China. As increasing the area of effective cultivated land and improving the quality and the scale of cultivated land are important orientations and goals of farmland consolidation, so it requires coordination between farmland consolidation and the quantity and quality of cultivated land to a certain degree. In order to find out this coordination both on space and time, based on the data of consolidation project from 2006 to 2012 by the Ministry of Land and Resources, combined with land use data and production of agricultural land classification and gradation, the paper first establishes consistency models and gravity center models by spatial analysis tools in ArcGIS at county level. Then the coordination of farmland consolidation and cultivated land resources is analyzed at national and provincial level. The results show that: 1) In terms of national level, 52.2% of farmland consolidation was arranged in the region of 14.4% of cultivated land during 2006 to 2012. It shows a poor coordination between farmland consolidation and the quantity of cultivated land resources. 2) When it comes to provincial level, the gravity centers of farmland consolida-tion are convergent to the gravity center of cultivated land in the majority of provinces. There is a good consistency between the arrangement of farmland consolidation and the distribution of cultivated land. 3) The proportion of farmland consolidation and cultivated land is relatively identical at each grade of cultivated land. The ratio of superior and inferior cultivated land increase gradually, while the higher grade shows a downward trend and the medium changes little. 4) We can easily find that the farmland consolidation gravity centers of each grade of cultivated land and the land gravity center are consistent in spatial distribution. The arrangement of farmland consolidation on superior and medium cultivated land becomes more and more balanced. The consolidation of higher cultivated land stresses to north and the consolidation gravity center of inferior cultivated land shows an annual difference. The above results reflect that the arrangement of farmland consolidation is unreasonable at national level. In some provinces, the current arrangement is not suitable to optimize sustainable development. It is necessary for the government to reduce the proportion of land development. Meanwhile, we can also find that the farmland consolidation becomes more and more balanced, and it also reflects a public welfare according to the increase of consolidation on inferior cultivated land. In the future, the guiding role of national land consolidation planning should be strengthened to standardize the provincial farmland consolidation project. We should take the opportunity to improve the quality of cultivated land of the whole country.

Key words: coordination, farmland consolidation, quantity of cultivated land, quality of cultivated land
