城市绿地对小气候影响的研究进展

Research advances on the effect of the urban green areas to microclimate

城市绿地对小气候的生态作用是研究城市绿地的重要问题。综述了国内外有关城市绿地对温度、湿度作用的研究报导,总结了城市绿地对温度、湿度影响的时空变化规律。目前城市绿地与温、湿度的关系多为定性研究,定量研究的技术与手段的局限使得定量研究还存在一定困难;城市绿地在美学、休憩等方面的潜在作用还无法定量研究;关于城市绿地群落结构与特性对小气候影响机制的研究还很少,这些都将是今后研究的重要方向。

The ecological effect of the urban green areas to the microclimate is a significant issue on the study of the urban green areas. In the paper, it is reviewed that researches on the temperature and humidity of the urban green areas at home and abroad, and the space-time rules of the temperature and humidity of the urban green areas are summarized. At present, many researches on the relationship between urban green areas and temperature and humidity are qualitative, and due to limitation on the technologies and methods, the quantitative researche are considerablely difficult; the potential effects of urban green areas, such as aesthetics and rest, are unable to research quantitatively now; And the researches on the mechanism that the community structure and characteristics impact on the microclimate are insufficient, which will be the important directions in the future.
