城市热岛现象随着我国城镇化发展表现的愈发突出，尤其南方湿热地区夏季高温天气持续时间长，城市热环境问题更为严重。目前研究多集中在城市热岛的现状、成因以及针对现状可采取的改善措施等方面，但对城市热环境改善并未起到明显作用。究其原因，是由于控制性详细规划（控规）指标及其组合配置对城市热环境响应特征的缺失，导致无法从源头节制城市热岛的蔓延。. 本项目以地处湿热地区的广州城区为研究对象，基于遥感数据，通过研究不同尺度和各类用地的地表温度与规划指标间关系，获得影响热环境的控规关键因子及其影响途径；通过改进城市冠层模型，提出适用于中尺度的城市热环境模拟方法，建立控规设计方案与城市冠层模型的结合途径，提出基于控规指标的城市热环境调控规划管理建议。本项目将从源头缓解城市热岛效应，减少城市能源消耗，提高人居环境质量，对实现国家健康城镇化战略具有重要意义。

With the urbanization, urban heat island phenomenon becomes more serious. The summer is hot and long in hot-humid region of China, and the problem of thermal environment is more severe. The previous researches focus on statuses and causes of urban heat island and some improvements, which don’t play a significant role to improve urban thermal environment. The reason is that the control index of regulatory plan and their combinations are little specific responses to urban thermal environment, resulting that it can’t stop the spread of urban heat island at source. . Focused on Guangzhou in hot-humid region of China, the present study is aimed to analyze the relationship between the surface temperature and the planning index in different scales and land use types based on remote sensing data, achieve the key factors of regulatory plan influencing thermal environments; by improving an urban canopy model, we propose a method suitable for simulating urban thermal environment in mesoscale, establish the ways combining the improved urban canopy model with regulatory plan, and put forward some plannings and management suggestions for regulating urban thermal environment based on the control indexes. This study will alleviate urban heat island effect at source, reduce the urban energy consumption, improve the quality of human settlements, and be of great significance to the healthy development of the national urbanization.
