浅述城市热岛效应的形成原因及其对策

在全球气候变暖和高速城市化的大背景下，世界上许多城市都出现了高强度的城市热岛效应，城市热环境质量日趋恶化。分析和评价城市热岛效应已经成为当前城市气候与环境研究的重要内容之一，也是全球变化研究的重要方面。介绍了城市热岛效应的定义，接着说明了城市热岛效应的形成原因，进一步说明了城市热岛效应对人们及周围环境带来的影响，最后提出了改善城市热岛效应的措施。

Brief Introduction of Reasons and Improvement Measures of Urban Heat Island Effect

Under the big background of global warming and high speed urbanization, high tensile urban heat island effect has been appearing in many cities in the world, the quality of urban thermal environment is deteriorating day by day. It has been one of the important contents of urban climate and environmental research to analyze and evaluate urban heat island effect, it is also an important aspect of global change research to analyze and evaluate the urban heat island effect. This article illustrates the definition of the urban heat island effect, it explains the reasons to come into being the urban heat island effect in the following, it makes further efforts to illustrate the influence on human health and ambient environment coming from the urban heat island effect, at last it presents the measures of improving the urban heat island effect.
