摘要 As an important measure of eco-environmental construction, the process ofde-farming in slope farmland is being undertakengradually in the whole China. Meanwhile, theproblem of reducing in food yield in de-farming areas can not be neglected any more. It is especially the case in areas with concentrated slope farmland andinconvenient transportation. In this paper, we analyze the causes of hidden troubles in food security, and the spatial relationship between farmland and slopefarmland in the reservoir area of Three Gorges, and unveil the spatial disparity of contradictions between food supply and demand. Finally, combining the accessibility of areas, three different spatial types offood security, food security area, food alert area, and food crisis area, are divided.
