城市热岛的影响因素及空间异质性的综述

Review of influencing factor and spatial heterogeneity of urban heat island

随着建设扩张的加快,城市环境发生了巨大的变化,其中值得特别关注的是热环境的变化。城市热岛的产生对于自然环境、人类健康具有一定的威胁与损害。因此,对城市热岛的检测及其影响因素进行分析,有助于城市实现健康发展和有效治理。基于此,文章研究了城市空间结构及植被指数等重要因素对城市热岛的影响,对不同区域的空间异质性进行了探索,分析了城市热岛的空间异质性分布情况。结果表明,建筑对城市有明显的升温作用,而绿地有明显的降温作用。

With the acceleration of construction and expansion,the urban environment has undergone tremendous changes,among which the change in thermal environment is worth special attention.The emergence of urban heat islands poses a certain threat and damage to the natural environment and human health.Therefore,analyzing the detection and influencing factors of urban heat islands can help cities achieve healthy development and effective governance.Based on this,the article studied the impact of important factors such as urban spatial structure and vegetation index on urban heat islands,explored the spatial heterogeneity of different regions,and analyzed the spatial heterogeneity distribution of urban heat islands.The results indicate that buildings have a significant warming effect on cities,while green spaces have a significant cooling effect.
