Based on the research of domestic and foreign scholars, this paper collates the environmental factor indicators of fish habitats in wetland parks, establishes the correlation between fish and environmental factors of habitats, and takes this as the design guidance of water area design, plant design, water quality management and maintenance, etc. in the construction process of fish habitats in urban wetland parks. The study found that the habitat quality of fish habitat was significantly affected by water quality (water temperature, dissolved oxygen, pH, sediment concentration), hydraulics (water depth, flow velocity), hydrology (flow), topography, coastal conditions, sediment, river channel coverage and human activities. Based on this, the habitat construction strategy is discussed from the aspects of water area design (water depth, sediment, shoreline, ecological revetment, ecological island, section design, microhabitat), plant design, water quality management and maintenance. Then the design strategy of the wetland park waterfront area based on fish habitat protection is proposed. Finally, taking Wuhu Dayanghan Wetland Park as an example, the specific measures for the construction and management of fish habitats are described.
