Abstract

This study is the first-ever attempt to relate the tools of development control like Floor Space Index (FSI/FAR), ground area covered by building footprints (BFs), and proportions/configurations of open areas, with their impact on the surface urban heat island (SUHI) which modulates the air temperatures. In the case of the Indian megacity Mumbai, statistical analysis of the land surface temperatures (LST) and its correlation with the selected development indicators, reveals that for an FSI increase of 1.0 to 1.8 the SUHI is found to be–2.5 °C less and when BFs reduced from 90% to 42% SUHI was also reduced by –2.5 °C. Highrise development with a large plot size is desirable whereas low-rise development with FSI 1.0 on small plot sizes exhibits the highest SUHI. Open spaces without vegetation do not reduce SUHI. The correlation of development regulations with SUHI intensity will help urban planners to make more informed decisions.

了解城市热岛的动态变化与开发法规的关系

本研究首次尝试将楼面空间指数（FSI/FAR）、建筑占地面积（BFs）和开放区域的比例/配置等开发控制工具与它们对调节气温的地表城市热岛（SUHI）的影响联系起来。以印度大城市孟买为例，对地表温度（LST）及其与所选发展指标的相关性进行统计分析后发现，当 FSI 增加 1.0 至 1.8 时，SUHI 降低了 2.5 °C，当 BFs 从 90% 降至 42% 时，SUHI 也降低了 -2.5 °C。地块面积大的高层开发项目比较理想，而地块面积小的低层开发项目（FSI 为 1.0）的 SUHI 最高。没有植被的空地不会降低 SUHI。开发法规与 SUHI 强度的相关性将有助于城市规划者做出更明智的决策。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
