Abstract:: The coordinated development of population, cultivated land and food is the important guarantee of regional sustainable development, is also the concerned hot spot in nowaday society. Taking Cangzhou City as the research case and applying the coordination degree function model, we evaluated the coordinated development degree of population, cultivated land and grain of 14 counties (cities) in Cangzhou City, and determined and identified the evolution of the three systems in Cangzhou City from 2003 to 2012, examined and analyzed the spatiotemporal variation of the regional coordinated development relation. The results showed that the population, cultivated land and grain composite system coordinated development level was not high in Cangzhou City. The coordinated development degree D value was about 0.52, which is at the basic level of coordination. From the point of view of time series, the population, cultivated land and grain composite system coordinated development level presented the fluctuating changes. There is no obvious rule to follow, but the level generally presented the rising trend. The three systems was not harmonious in 2003, while was given priority to more coordination and high coordination. From the point of spatial distribution, the coordination development level and the average annual growth rate of the three systems in 14 counties or cities in Cangzhou City, the coordinated development level in Wuqiao County was always the highest, it was the lowest in Haixing County. The average growth rate of coordinated development degree in Qing County was the highest (8.60%) and it was the lowest (0.33%) Wuqiao. The coordinated development level in southwest was the highest, followed by the central region and the western region, it was the lowest in the eastern area. This research could provide the reference for early warning mechanism of the development of regional food security, making different polices of agriculture, rural areas and farmers, promoting regional balanced development of regional agricultural ecological economic system.
