Consideration of river governance based on the concept of urban spatial resilience

Abstract The reasonable scale of urban river ecological space and the connectivity bank slope water soil exchange are basic conditions to keep flow matter, energy species in unimpeded, as well way out for dilemma governance. concept resilience spatial planning is used break artificial partition between land space, explore compound function realize integration synergism space.The research shows that scientific overall rational utilization basis realizing combination solving governance predicament. Urban layout should highlight backbone role river-dominated eco-environment texture, restore network corridor, build public open optimize use resources achieving functional compounding; Meanwhile, expand three-dimensional river, increase diversity, improve openness waterfront balance through collaboration. To boundaries waters areas form area, environment management design needs focus on key elements such plane shape, sections, treatment reconstruction protection, temporal evolution rivers. Application multi-natural restoration, near-natural construction, semi-natural flood control other technologies can achieve effect protection permeability slope. By opening up it provides a limited dynamic change bed evolves with time, which conducive exerting corridor system driving improvement promotion areas.
