摘　　要：【目的】以北京市海淀区平原造林重点项目中关村森林公园作为研究对象,探讨其对大气颗粒物的消减作用。【方法】采用实地调查的方法,针对不同植物配置模式对大气颗粒物的消减作用进行调查研究。【结果】在轻度以及中度大气污染条件下,公园对大气颗粒物存在明显的消减作用,乔灌草植物配置模式对大气颗粒物的消减作用最显著,与其他植物配置模式相比,表现出显著的差异性(P<0.05)。在重度污染情况下,公园对大气颗粒物的消减作用消失。【结论】平原造林工程对大气颗粒物的消减作用显著,此项研究结果可为北京市平原造林工程以及植物配置模式的选择提供理论依据。【Objective】Zhongguancun Forest Park,a key project of plain afforestation in Haidian district of Beijing,was as the study object,and its subtraction effect on atmospheric particulate matters was explored.【Methods】Based on field survey,the subtraction effect of different plant configuration modes on atmospheric particulate matters were investigated.【Results】The results show that under the condition of mild to moderate air pollution,the park had a significant subtraction effect on atmospheric particulate matter.Among different community structures,arbor-shrub-grass mode presented the greatest subtraction effect,which was significantly higher than other modes(P<0.05).But under the condition of severe air pollution,the park did not show significant subtraction effect.【Conclusion】The plain afforestation project had a significant effect on reduction of atmospheric particulate matters when the air pollution was mild and moderate.This result provides the theoretical basis for the selection of plant configuration modes in the plain afforestation project in Beijing.
