Abstract: How to enhance the "ecological governance" urban policy mobility in a more scientific way, rather than simply replicating exotic "model" policy?This is not only related to the improvement of China's urban ecological environment, but also a revolution jumping out of the established rigid policy design "inertia". Based on the framework of the urban policy mobility and Deleuze's "Becoming" thoughts, "Yichang Experiment", an ecological governance policy, was reshaped by balancing policy and nature and improving procedural and spatial policy design. First, being ecology-centered, enhancing public engagement, and reducing the political impact and best-example awareness were taken as the key to realizing subject disintegration; second, multiply items of "series" "structures", "disadvantaged groups" and "disadvantaged knowledge" were used to improve ecological protection policy, ecological industry and monetary policy, ecological science popularization policy; at last, music model was applied to keep two aquatic ecological and humanistic corridors in harmony, ocean model was used to transform different spaces of special ecological towns, mathematical model to develop government performance evaluation system with ecological and economic development indicators, and aesthetics model to extend the ecological space design.
