Application of Computer Aided Design in the Optimal Design of CBD Micro-green Space: Take Tianhe District, Guangzhou as an Example

Abstract

In urban renewal and fine governance, micro-green space plays a crucial role in the urban central business district (CBD) due to its efficient use of space, environmental enhancement, and contribution to residents' quality of life. This paper focuses on six representative micro-green spaces in Tianhe District of Guangzhou as its research subjects. Employing the post-use assessment (POE) method, combined with questionnaire surveys and interviews, this study conducts data collection and coupling analysis on the physical space status, user behavior, and demand of green spaces from the user perspective. The results indicate that while the micro-green space construction foundation of the CBD in Tianhe District of Guangzhou is sound, several common problems exist in urban green space planning, facility perfection, regional characteristics, and later maintenance. In light of these issues, and in conjunction with user needs, this paper proposes an optimization design strategy comprising system planning and function integration, soft space boundary layout, additional landscape facilities, multi-level plant healing space, and cultural landscape with Guangfu characteristics. A more intuitive computer-aided design method is employed to simulate the landscape optimization design results of micro-green space, aiming to meet the needs of the public and enhance the quality of the urban environment. This will further improve the quality of the urban ecological environment and citizens' quality of life.
