During the process of the high-speed urbanization in Chinese cities, the social, economic, and political status and the interaction between each factor have been more focused on urban traditional district renewal. However, the effects on urban microclimate and the residential living conditions in traditional districts are not well discussed, which is strongly related to the living comfort and citizens' well-being. In this study, two typical traditional districts in Xi'an are selected. According to the original situation of building functions and the community characteristics, two renewal plans are proposed by adding vegetation in open spaces (V), and adding vegetation combined with building redevelopment (V&B), in order to balance the living convenience and thermal environment. Via ENVI-met simulation, the effects of the district renewal plans on thermal environment including wind speed, air temperature, and mean radiant temperature are evaluated. This study provides method of environmental evaluation for traditional district renewal, which contributes to sustainable urban planning in historical districts, and provides recommendations for related policy development.
在中国城市的高速城市化进程中，社会、经济和政治地位以及各因素之间的相互作用，更多地集中在城市传统区域的更新上。然而，对于城市微气候和传统区域的居住生活条件的影响却没有得到很好的讨论，这与居住舒适度和市民的幸福感密切相关。本研究选取了西安的两个典型传统区域，根据建筑功能的原始情况和社区特点，通过增加开放空间的植被（V）和增加植被结合建筑再开发（V&B），提出了两种更新方案，以平衡生活便利性和热环境。通过 ENVI-met 模拟，评估了区域更新方案对风速、空气温度和平均辐射温度等热环境的影响。本研究为传统区域更新提供了环境评估方法，有助于历史区域的可持续城市规划，并为相关政策制定提供了建议。
