The rapid urbanization in China has led to the transformation of a large number of suburban agricultural land into urban land, where agricultural production is replaced by industry and services, and landless famers are forced to pour into the city to engage in non-agricultural work that they are not good at. The purpose of this study is to explore a more systematic model of urban agriculture development to enable an efficient symbiosis between the city and agriculture. Based on the theory of industrial ecology, we established the coupling system model of material, industry and population. In this model, the cultivated land can be reconstructed on the roof of the factory buildings by stripping the cultivated soil of the new industrial park, and consequently the agricultural production and industrial production are superimposed in space. The perfect infrastructure in industrial parks can contribute to the development of high value-added agriculture, and landless farmers can continue to engage in agricultural production which they are good at in the area. Then, we selected Yubei District Airport Park, Chongqing, as a case to apply this model. The interaction between material, industry and population is analyzed, and the corresponding economic output value, ecological value and social function are measured, which proved the rationality and necessity of the superposition development model of urban agriculture and industrial park to exist in urban environment system. And that will be an important step in the move towards a more sustainable society.
