Optimizing Cropping-Breeding Coupled Mode of Urban Agriculture Based on Ecological Civilization

In the grim situation of tighter resource constraint,serious environmental pollution and ecological system degenerate,the construction of ecological civilization is lifted to the strategic height which is hitherto unknown in the eighteenth NCCCP.One-sided emphasis on the social civilization will have negative effects on the natural ecology,and we also can't limit production activities simply for natural ecology.Ecological civilization is the perfect fusion of the ecological and social civilization.The modern agriculture is an important carrier of the construction of ecological civilization due to industrial property,and urban agriculture is specially important in the construction of the ecological civilization for special environment.The important role of urban agriculture in the construction of ecological civilization is ultimately achieved by optimizing cropping-breeding coupled mode.The authors analyzed the optimization direction of urban agriculture cropping-breeding coupled mode from basic requirement of ecological civilization construction and ecological impact characteristics of agricultural production,and discussed induction mechanism of cropping-breeding coupled mode,which consists of agricultural technology innovation and system construction.
