Abstract: Based on the practice of domestic and foreign scholars in the design characteristics of vertical greening，this research explores the design methods of high-rise office buildings based on vertical greening and their influencing factors by the balanced design method from three aspects， including public space form， public space experience， and public space function，and then provides the optimization design methods of vertical greening in public space of high-rise office buildings. Using different design methods of the vertical greening of buildings provides ideal interior architectural space，such as increasing the contrast between virtual and reality， clarifying the change of light and shadow， grasping the rhythm，coordinating the proportion and scale，strengthening the continuity of the public space，optimizing the transition space， deepening the connection between interior and outdoor space，blursing the boundaries. Meanwhile，the vertical greening designed strategy of the building is improved to meet the needs of users，fit the circulation guiding function of public space，and increase the greening rate and optimization rate of the space. Combining the leisure and entertainment functions of public space with vertical greening design will improve the subjectivity of the public space. The three-dimensional greening design of the public space is helpful to solve the spatial experience problems of lack of hierarchy，landscape environment， and good comfort in high-rise office buildings， and it provides the optimization of the public space experience for users of high-rise office buildings.
