建筑群布局与空间几何形态、下垫面物理属性以及人为热排放是影响城市热岛的3大人为因素。近年来,针对城市热岛与影响因素的研究层出不穷。对城市人为热及其影响室外热环境的研究进行梳理是对影响城市热岛的人为因素进行研究的完善和补充。本文从城市人为排热量统计、人为热对城市室外气温的影响2方面展开,对国内外相关研究进展进行综述,对研究对象、人为排热量计算方法和人为排热量对城市热环境影响研究方法 3个方面进行总结,并提炼了一些重要结论。本文为该领域接下来相关研究工作的重点提供了线索,即关注人为热排放与城市规划重要指标的关系,探索人为热对城市热环境的影响机理和内在规律,从而提出更全面、更有效改善城市气候的措施。
The layout and spatial geometry of buildings, physical properties of underlying surface and anthropogenic heat emission are the three major human factors that affect the urban heat island. In recent years, research on urban heat island and its influencing factors are emerging in an endless stream. The research on urban man-made heat and its impact on outdoor thermal environment is the improvement and supplement to the research on the human factors that affect urban heat island. This article starts from the analysis of urban anthropogenic heat emission and anthropogenic heat on urban outdoor air temperature. It summarizes the relative research progress both at home and abroad. The research object, anthropogenic heat emission calculation method and anthropogenic heat release on urban thermal environment are studied. Method 3 Summarize aspects, and refined some important conclusions. This article provides the clues for the following research work in this field, which focuses on the relationship between anthropogenic heat emission and important urban planning indicators, explores the mechanism and inherent law of anthropogenic heat on the urban thermal environment, and proposes a more comprehensive and effective improvement Urban climate measures.
