Abstract: Urbanization is an inevitable trend of global development. However, it has caused many problems such as the heat island effect, urban flooding, and environmental pollutions. Therefore, a sustainable urban development model was proposed, that is, the future city will coordinate the harmonious coexistence of humans and nature, retain stormwater, reduce urban energy consumption, and recycle urban organic wastes by adopting green infrastructures. The scientific problems that need to be solved were proposed to achieve the natural future city.

Key words: nature-based solution; green infrastructure; urban flooding; cooling; organic waste recycling
