“…In the construction process of sponge cities, it is necessary to pay attention to urban greening, carry out wetland protection, collect rainwater by installing rainwater collection devices within the city, demolish a large area of cement pavement and replace it, consider the natural discharge of rainwater in the urban design process [10][11][12]. The purpose of building sponge cities is to alleviate the drainage pressure of the city, improve the utilization efficiency of water resources, increase the green coverage rate of the city, and improve the ecological environment of the city.…”

In recent years, people have increasingly attached importance to the application of sponge city theory in urban planning, but often overlooked the urban water regulation role played by urban parks. This paper analyzes the connotation and relationship between sponge cities and urban parks, lists the planning principles of urban parks, and proposes design strategies for sponge urban parks. In the planning and design process of sponge urban parks, rainwater management can be optimized by facilities, vegetation planting methods can be improved, and these can be combined with the current situation of urban parks to build a strong organizational and efficient green rainwater management system. This system not only ensures the viewing effect of the garden, but also effectively recycles and utilizes natural rainwater to form a complete sponge network, effectively promoting the construction of sustainable sponge urban parks.

In order to confirm the performance of recessed green space in rainwater collection and utilization of urban roads, this paper proposes a corresponding experimental test program, which mainly covers the evaluation of rainwater infiltration, the evaluation of rainwater purification, and the simulation of rainfall-runoff reduction. Using the above test methods, the effectiveness of recessed green space in collecting and utilizing rainwater was analyzed. The results showed that in the one-way analysis of the compositional structure of the undercroft green space, the gravel layer, the media layer, and the vegetation layer had no significant difference in the infiltration rate sig<0.05, and all three had no significant difference with the infiltration rate. The order of rainwater infiltration effect of the four reactors was 3/7 mixed media reactor (23.08 ml/min) > red loam reactor (23.04 ml/min) > 2/8 mixed media reactor (23 ml/min) > black loam reactor (23.08 ml/min), while the order of purification effect was 3/7 mixed media > 2/8 mixed media > red loam > black loam. In addition, the combined high infiltration hypolimnetic green space had a better retention effect (flow yield range from 0 to 10 L) in rainfall-runoff with a reproduction period of 3 and 4 years. Based on the analysis results, the application effect of undercroft green space in urban road rainwater collection and utilization is comprehensively verified, and it is hoped that the investigation of this paper can bring certain references and references to the relevant personnel.
