The sponge city design proposal based on landscape design: taking Gaochun, Nanjing as an example

Landscape design plays an important role in connecting urban functional areas, ecological purification and beautifying the environment in rainwater treatment. In response to the rainwater problem, China has learned from European and American more mature solutions and proposed sponge cities by combining its own characteristics. However, there still exist problems of insufficient landscape design utilization in the construction of sponge cities. By comparing excellent landscape design cases of “low-impact development”, “sustainable urban drainage system”, and “water sensitive urban design”, this article reaches the conclusion that the significance of landscape design lies in not only cooperating with engineering rainwater treatment methods but providing public space with lasting economic, social, cultural, health and environmental benefits. With such design goals, China’s sponge city construction should Combine humanities and history and cooperate with different environmental assessments in various regions to establish a landscape system suitable for urban development and human living.
