However, under the background of modern urbanization, urban living environment is out of the traditional history and culture and facing such issue as cement jungle. In order to improve the living environment and make the city coordinate with the natural environment, the development of modern urban gardens needs inheritance and development of traditional garden practices. The planning and design methods with scientific guidance were studied in this paper through exploring the application of garden design style in Tang Dynasty in the design of modern city public gardens, so as to inherit the classical garden culture and create a city open space that meets the needs of contemporary citizens as well.展开更多
