At the end of the 20th century, highly urbanized areas began to explore water-sensitive urban design. In recent years, with the gradual expansion of China's urban scale, a large number of people enter the city to settle down, the pressure on urban roads is also increasing, and the limited ability of rainwater infiltration on roads leads to serious water logging in the city when it comes to the rainy season. Sponge city not only solves the problem of urban flooding, but also makes full use of rainwater resources, and will further alleviate the problem of water shortage. This paper takes the design perspective of "sponge city" in water-sensitive urban design as a starting point, explains the origin, connotation, multi-scale construction method and practice of the concept of "sponge city", and combines the Potsdamer Platz in Germany and the Vertical Forest Architecture Case in Italy, to understand the design of sunken green space in sponge city system and the architectural design of vertical garden style in resilient city.
