城市绿地缓解热岛效应研究进展

A Review of Urban Green Space on Mitigating the Heat Island Effect

城市热岛强烈地影响着城市生态系统,对城市气候、水文、土壤、大气环境、生物习性以及城市居民健康等产生影响.城市绿地作为城市生态系统重要的组成部分,通过改善城市下垫面的热属性,具有一定的缓解热岛效应作用.因此,选取城市热岛效应研究方法、研究尺度性、城市绿地结构和土地利用类型的降温效果、绿地与其他因素之间的交互作用等角度综述城市绿地缓解热岛效应的关系,并比较分析当前研究手段和方法的优缺点,最后在观测手段、数据来源、长期动态观测和模拟定量研究等方面对该领域的研究进行展望.

The Urban Heat Island（UHI）effect has strong influences on the urban ecosystems,including urban climate,hydrology,soil,atmospheric,biological habits and public health.As an important part of the urban ecosystem,the green space could mitigate the UHI effect by regulating urban surface thermal properties.The research progress of the effect of urban green space on mitigating the UHI effect was reviewed,including UHI research methods,research scale,cooling effect of different urban green space structures and land use types and the interactions between green space and other factors.The advantages and disadvantages of current research ways and methods were summarized and the research was forecasted on the aspects of multi-observation tools,multi-source data,the long-term dynamic monitoring and quantitative research.
