This paper puts forward the innovative scheme and implementation strategy of Hemu urban wetland. The plan considers its historical context and current status, its conservation significance, strategies, solutions and supporting conditions. It highlights the landscape features of rivers and lakes, and restores its historic flood control function and urban climate regulation. In particular, the paper proposes to restore the farming practice of “mulberry sided fishponds,” an important agricultural heritage created by the ancestors of wetlands, as a unique and innovative method of using lowland areas for ecological agriculture and circular economy. The proposed wetland sewage treatment scheme has practical significance for improving the ecological environment and promoting the ecological civilization construction in this area. The protection and utilization planning of “two-area and one-area triplet” is reasonable and feasible, which fully reflects the production, life, life form and ecological function of wetlands, and has the characteristics of wetland joint protection. It will lead to active rather than passive wetland conservation, such as the conversion of “blood transfusion protection” to “hematopoietic protection”, which reflects sustainable development. This paper provides valuable information and strategies for urban wetland planning and development.
