Abstract:In recent years, Garden Show (Garden Festival) has been developing rapidly in China. As an important part of Garden Show at all levels, urban garden plays an important role in displaying urban culture and regional characteristics. The Shenzhen Garden of the International Horticultural Expo 2021 Yangzhou covers an area of 2 500 square meters. With the theme of “Harmonious Home”, the design concept emphasizes breaking through the extraction and reappearance of urban landscape elements. Through the optimization of terrain space, the display of regional plant habitat and the interesting audio-visual design, a high-quality open space with a double ring structure is created, and the vitality and charm of Shenzhen City are displayed.
