Abstract: Whether urban wetland park can play its ecological function mainly depends on its spatial distribution pattern. According to the optimization concept of pattern-process-function integrity, the spatial pattern of Liuli River Wetland Park was optimized by optimizing landscape structure, regulating the hydrological circulation process and hydrological cycle process, and optimizing the spatial configuration of Liuli River Wetland Park, so as to achieve the purpose of improving the function of the study area. The results showed that the study area could be divided into 2 primary functional zones and 9 secondary functional zones. Through regulation of hydrologic circulation process and hydrologic cycle process, the water areas increased by 0.68 km ². Based on pattern optimization and hydrologic regulation, the space optimization scheme including patch configuration and corridor configuration was proposed. The number of patches might increase by 924, the wetland area increased by 146.51% and the functions of water purification, species conservation, ornamental and educational functions were greatly improved in the study area after optimal configuration.
