城市化的迅速发展导致了污染、人类活动产生的废热、多种疾病、水资源紧张等形式的所有负面影响的累积效应。随着城市和城镇的发展或扩张，大量植被沿着丧失，城市表面被建筑物铺设或覆盖，导致更少的阴影和水分，以保持城市地区凉爽。它揭示了这样一个事实，即建成区蒸发较少的水，导致城市的表面和空气温度升高。城市热岛效应的大小是根据城市材料的性质来确定的，这些性质包括太阳反射率、热发射率和热容沿着以及反射、发射和吸收太阳能的能力。这些概念问题导致城市地区相对于农村地区变暖，这种现象被称为“热岛效应”。本文论述了城市热岛效应对城市环境的影响及其规划。还努力提出缓解措施，以消除城市地区的热岛效应。
The rapid growth of urbanization leads to the cumulative effect of all the negative impacts in the form of pollution, production of waste heat from human activity, multiple diseases, water stress, and so on so forth. With the development or expansion of cities and towns significant vegetation is lost along with urban surfaces are paved or covered with buildings resulting into less shade and moisture to keep urban areas cool. It reveals the fact that Built-up areas evaporate less water resulting into elevated surface and air temperatures of the cities. The amount of urban heat island effect is experienced based on properties of urban materials which consist of solar reflectance, thermal emissivity and heat capacity along with ability to reflect, emit and absorb the suns energy. These conceptual issues lead to warming of urban areas as compared to their rural surroundings, a phenomenon known as the “heat island effect.” An effort has been made in the present paper by the authors to describe the effect of heat island effect on urban environment and its planning. An effort has also been made to suggest mitigating measures to combat heat island effects in urban areas.
