摘要：随着城市的不断扩张,PM_(2.5)污染凸显,引起广泛关注。研究表明,城市林木为城市环境提供了重要的生态保障,在调控、缓解、降低城市PM_(2.5)污染危害等方面发挥极其重要的作用,通过筛选树种、优化配置结构、提高林木质量等方面进行城市林木前瞻性布局。然而,结合前期研究基础如何进一步深入研究并研究突破城市林木调控PM_(2.5)污染机制与机理,实现调控PM_(2.5)效应的最大化、最优化,依然是一个亟待解决的难题,这迫切需要在多尺度、多维度进行调控PM_(2.5)效应研究,并在不同尺度、不同维度进一步进行结合、延伸。对基于实地监测的城市林木调控PM_(2.5)能力研究现状相关文献进行归纳总结,并从林木单位叶面积与形态特征、配置结构特征、气象条件以及其他因素等方面归纳城市林木调控PM_(2.5)机制,同时从城市林木调控PM_(2.5)效应的时间变化特征、水平距离和垂直变化特征、内外变化特征等方面总结城市林木调控PM_(2.5)时空特征。最终提出研究城市林木调控PM_(2.5)效应目前存在的主要问题以及未来研究展望。
With the development of urbanization,PM2.5 pollution is prominent,more and more attention has been focused on PM2.5pollution in the cities.The research showed that urban trees provides an important ecological guarantee for the urban environment,plays an extremely important role in regulating,alleviating and reducing the urban PM2.5 pollution hazards,and carries out the forward layout of urban trees by selecting tree species,optimizing the configuration structure and improving the quality of forest trees.However,how to further study the mechanism of PM2.5 pollution regulation by urban trees and realize the maximization and optimization of PM2.5 effect is still a problem to be solved.It is urgent to conduct the study of PM2.5 effect in multi?scale and multi?dimensional,and further combine and extend in different scales and dimensions.In this paper,based on the field monitoring of the PM2.5 capacity of urban trees regulation,the relevant literature regarding the PM2.5 mechanism of urban trees regulation was summarized in terms of the unit leaf area and morphological characteristics,configuration structure characteristics,meteorological conditions and other factors.At the same time,the temporal and spatial characteristics of urban trees regulation PM2.5 were concluded in terms of the temporal change characteristics,horizontal distance and vertical change characteristics,internal and external change characteristics of the PM2.5 effect of urban trees regulation.Finally,the paper puts forward the main problems and future research prospects of PM2.5 effect of urban trees regulation.
