[0002] With the acceleration of urbanization, urban rivers are facing challenges and are suffering from pollution, degradation, drying up, extinction and other dangers. For river regulation, revetment reconstruction is an important part, but the engineering governance measures are costly and ineffective. With the development of ecology, more and more scholars have begun to pay attention to the ecological benefits brought by urban rivers, and gradually began to use ecological revetments instead of hard revetments. Therefore, scientific and reasonable restoration and governance of damaged ecosystems of urban rivers should be formulated to accelerate the pace of urban river governance in the international community and provide an effective demonstration for the construction of ecological cities.
