城市空气花粉的研究进展

Advances in urban airborne pollen

通过综述城市空气花粉的研究进展,总结城市空气花粉的采集方式并进行对比,分析各主要城市的空气花粉的种属以及时空传播规律以及各地理环境和气候条件与空气花粉的关系,并指出了研究中存在的问题,并对研究前景进行了展望。对研究进展进行总结可知,城市化所伴随的交通污染,热岛效应,城市绿化和硬质地面增多等现象会在一定程度上增强了空气花粉的致敏性,对空气花粉的飘散起到积极影响,因此,能够加剧花粉症的发病情况。而基于空气花粉研究存在的样品采集技术的问题,原因分析太浅现和不能很好解答科学问题等三大现状,笔者提出注重相邻城市之间的空气花粉的研究,与遥感技术相结合进行分析和结合现实问题进行研究等三个未来的研究方向。

By reviewing the advances in urban air pollen, it summarizes and compares the collection methods of urban air pollen, analyzes the species of air pollen, the law of space-time propagation, the relationship between the geographical environment and climate conditions and the air pollen, points out the problems in the study, and looks forward to the prospect of the research. The summary of the research progress shows that the traffic pollution, the heat island effect, the urban greening and the increase of the hard ground will increase the sensitivities of the air pollen to a certain extent, and have a positive influence on the air pollen dispersal, so it can aggravate the incidence of pollen disease. Based on the problem of sample collection technology in the study of air pollen, the analysis of the reason is too simple and can not solve the scientific problems. The author puts forward three future research directions, such as the research on the air pollen between contiguous cities, the combination of remote sensing technology and combination with the practical problems.
