摘　　要：热岛效应导致城市人居热环境恶化,并造成能源的巨大消耗,如何有效缓解热岛效应已成为迫切需要解决的问题。植被可以通过遮蔽长短波辐射和蒸腾等作用起到降低气温、增加湿度的效果,因此,城市绿化已成为一种缓解热岛效应的重要技术手段。为继续推动植被对城市热岛效应影响的研究,分别从研究现状、研究内容和研究方法、存在问题与展望等方面对国内外的相关研究进行梳理与综述。首先从城市热岛效应的研究起源、观测方式等角度梳理了国内外的研究进展。在此基础上,进一步分析了植被对城市气温的调节机理,并分别从植被垂直结构、水平结构、冠层结构等空间结构视角与植被遥感指数视角,进一步对植被的降温效应机理进行了综述。其中,植被冠层结构包含叶面积指数、冠幅、郁闭度、绿量等参数,遥感指数包含归一化植被指数、植被覆盖度、绿度植被指数等参数。除对国内外的研究现状进行综述外,还总结了目前绿地降温效应研究中的主要问题,并在未来研究方向等方面提出建议,为后续研究提供借鉴和参考。Heat island effect leads to the deterioration of urban residential thermal environment and the consumption of large amount of energy. How to effectively alleviate the heat island effect has become an urgent problem. Vegetation can reduce air temperature and increase humidity through long-wave and short-wave radiation and transpiration. Therefore, urban greening has become an important technical means to alleviate the heat island effect. In order to continuously promote the research on the impact of vegetation on urban heat island effect, this paper reviews and summarizes the relevant studies at home and abroad from the aspects of research status, research content and research methods, existing problems and prospects. Firstly, the research progress of urban heat island effect at home and abroad is reviewed from the perspectives of research origin and observation methods. On this basis, the regulation mechanism of vegetation on urban air temperature is further analyzed, and the mechanism of vegetation cooling effect is further summarized from the perspectives of vegetation vertical structure, horizontal structure, canopy structure and vegetation remote sensing index. Among them, vegetation canopy structure contains parameters such as leaf area index, canopy width, canopy density and three-dimensional green biomass, while remote sensing index contains parameters such as normalized vegetation index, vegetation coverage and greenness vegetation index. This paper not only summarizes the research status at home and abroad, but also concludes the main problems in the current study of the cooling effect of green spaces, and puts forward suggestions for future research directions, which aims to provide references for follow-up research.
