From the two aspects of river health and livability, 11 indicators were selected to construct the membership degree weighted evaluation model based on subjective and objective weighting method, and the coordinated development degree model was constructed. The above models were used to evaluate the construction status of Happy River in the main stream of the Feiyun River from 2016 to 2019. Improvement suggestions were proposed, including reducing human interference in river regulation, restoring ecological water demand, rational planning of water resources and deepening rive social service functions. The results show that the overall Happy Rive construction is inclined to the second level of happiness, and the coordinated development status is in the medium coordinated development stage, indicating the development tendency to well-coordinated development stage. Indexes such as water resources development and utilization efficiency, economic level of urban and rural residents, ecological water satisfaction degree, discharge process variation degree and river connectivity restrict the happiness level promotion for the Feiyun River.
