城市空气污染的植物监测研究进展

Plant monitoring of urban air pollution

通过分析国内外大量的相关研究,探讨了植物对空气污染的响应以及空气污染植物监测的传统途径和高光谱技术,结果发现,如何基于当地大气污染物的状况和种类有针对性地筛选植物指示种及其关键响应参数以及如何利用获取的信息来科学地解释城市空气质量及其在不同尺度上的差异,依然是当前研究中面临的难题.

Urban air pollution is seriously detrimental to physical and mental health of residents, leading to deteriorated living quality. It is therefore necessary to take effective monitoring measures to provide useful information to alleviate the effect of air pollution. Plant monitoring is a main method to assess air pollution. Major reports have been analyzed to assesse response of vegetation to urban pollution with both traditional and hyperspectral means of plant monitoring. Major problems encountered in current research were found to include, selecting target indicators and key response parameters according to status of local air pollution; scientifically explaining urban air quality related to scale effect based on acquired information.
