Every aspect of urban planning, design, and construction, should consider the impact on the natural ecology and the protection of natural systems, especially the natural water cycle. This article takes Suzhou Taihu Garden Expo Park (starting now referred to as Garden Expo Park) as the research object. The park applies sponge technology to the construction of the green landscape while creating the garden landscape. The subproject design created the  rst “sponge country park” pilot project in Jiangsu Province, which not only meets the functional requirements of the gardening but also demonstrates the concept and construction results of the sponge city. Through the research on the related concepts and current status of the sponge city, and the landscape planning and design practice of the garden park, the speci c technical design and application of the sponge city described; hope that the sponge city concept and technology can be applied to the green space construction to better communicate with the city. The fusion of landscapes also provides a valuable reference for urban construction and management and the sustainable development of tourist parks.
