Abstract：Governance and ecological restoration of polluted rivers shall be the key link to realize recovery and safeguard high-quality development of the river basin.Considering multiple needs of pollution control and ecological recovery,a synergistic and progressive ecological recovery strategy is proposed with a focus on"overall planning and systematic governance".It proposes a collaborative framework based on large-scale coordinated operations,multi-scale collaborative governance,multi-dimensional collaborative design,and full-cycle collaborative implementation.It integrates the progressive path of weaving a network,addressing the root causes,cleaning water bodies and banks,protecting water sources and constructing green waterways.It integrates the main body of implementation,stage planning and restoration process to restore the ecosystem of polluted rivers step by strep.According to this strategy,ecological recovery of the Maozhou River in Shenzhen of Guangdong Province has been conducted by key technologies such as comprehensive governance,root cause analysis,blackwater elimination and green waterway construction.After its implementation,the integrated pollution index of the mainstream of the Maozhou River decreased by 92.28％compared with that before.Concentration of COD,ammonia nitrogen and total phosphorus,which are the main pollution indicators,decreased by 76.70％,96.63％and 97.46％respectively.Water quality met the Class Ⅳ surface water standards.The ability of river courses to recover from rainfall has been enhanced year by year,with an index of biodiversity increased by 21.43％.Ecological restoration of the river has been promoted continuously and steadily.
