Abstract: To explore the law of interaction between urban agricultural development and resources and environmental carrying capacity has great importance to promote the development of urban agriculture, solve the resource and environmental problems in urban development and promote the sustainable development of Nanjing. On the basis of scientifically constructing the evaluation index system of urban agriculture development and resources and environment carrying capacity, this paper uses the coupling degree model and takes Nanjing city as an example to make an empirical study on the coupling coordination relationship between them. The results show that the development level of urban agriculture and the carrying capacity of resources and environment in Nanjing have been increasing from 2000 to 2015. There is a positive correlation between each other. When the carrying capacity of the resources and environment is increased by 1%, the comprehensive evaluation value of urban agriculture in Nanjing is increased by 0.746%.The degree of coupling coordination is imbalance from 2000 to 2007, into the coordination stage from 2008 to 2015, is only 0.637 which in primary coordination in 2015. The type of coupling coordination is lagging behind the carrying capacity of resources and environment. Based on the foundation of resources and environment, Nanjing should scientifically plan the pattern of urban agriculture development; change the mode of resource development and environmental protection to ensure the sustainable development of urban agriculture; increase policy support to promote the collaborative optimization of urban agricultural development and resources and environmental carrying capacity.
