Through the analysis of the origin and development of hanging gardens, author of this paper summarized three typical types of hanging gardens in higji-rise apartment buildings, analyzed advantages and factors affecting the design of hanging gardens,and concluded main design points of llie gardens. It is believed that in the process of planning, design, construction and management of tiie hanging gafdens in high-rise apartment buildings in China, demand characteristics of different use groups should be taken into account, much emphasis should be placed to service to people than, visual pursuit, and human behaviors should be combined with built environment, thereby achieving the blending of people and scenery.展开更多
