中文摘要 探究北京西、北环山因素影响下的相同结构植物群落PM₁₀浓度差异,可从城市视角为公园植物群落搭配及提升设计提供参考。本研究以北京市海淀区为例,测定不同山体位置关系下5个公园内20个典型植物群落PM₁₀浓度,分析不同植物群落内PM₁₀浓度时空变化、植物群落结构对PM₁₀的消减作用、PM₁₀浓度与温度及空气相对湿度的关系。结果表明:1)山体距离因子与PM₁₀浓度空间分布具有一定正相关关系,植物群落PM₁₀浓度日变化趋势呈现出U型的分布状态;2)植物群落结构PM₁₀消减率为草坪型＞乔灌草型>乔草型>乔灌型;3) PM₁₀浓度与温度呈负相关关系,与空气相对湿度呈正相关关系,且温湿度对与山体距离远的公园影响更大。

英文摘要 This research explores the variation of PM₁₀ concentration in plant communities with the same structure, which are under the influence of mountains along western and northern area of Beijing, and the results is expected to provide reference for the plant community configuration in parks and the improvement of plant community design from the urban perspective. The authors measures PM₁₀ concentration in 20 typical plant communities from 5 parks with the different location and mountain relationship in Haidian District of Beijing, so as to analyze the temporal-spatial variation of PM₁₀ concentration, abatement of PM₁₀ emission by plant communities, and relationship between PM₁₀ concentration and temperature and air relative humidity in these plant communities. The results show: 1) There is a positive correlation between mountain distance and the spatial distribution of PM₁₀ concentration, and the daily variation of PM₁₀ concentration in plant community tends to be a U-shaped distribution; 2) PM₁₀ abatement rates of various plant communities rank as lawns > arbor-shrub-grass lands > arbor-grass lands > arbor-shrub lands; and 3) PM₁₀ concentration is negatively correlated with temperature and positively correlated with relative humidity of air, and temperature and humidity have a greater impact on the parks with longer distance from the mountains.
