摘要: [目的] 以北京地区经济林两个品种杏"串枝红"和"龙王帽"为研究对象,定量分析经济林吸滞环境中颗粒物质量浓度,充分发挥经济林的生态效益。[方法] 采集两个品种杏的叶片,应用气溶胶再发生器(QRJZFSQ-I)测定两个品种杏叶片吸滞空气中TSP、PM10、PM2.5、PM1.0的能力。[结果] "串枝红"单位叶面积吸滞颗粒物能力比"龙王帽"强,吸滞TSP、PM10、PM2.5、PM1.0量分别是"龙王帽"的2.54、1.80、1.72、1.57倍;10月份不同品种杏单位叶面积吸滞TSP、PM10、PM2.5、PM1.0的量最多,"串枝红"单位叶面积吸滞量分别为:(4.87±0.05)μg/cm2、(3.90±0.07)μg/cm2、(2.02±0.008)μg/cm2、(0.87±0.09)μg/cm2,"龙王帽"单位叶面积吸滞量依次为:(2.58±0.008)μg/cm2、(2.52±0.05)μg/cm2、(1.14±0.12)μg/cm2、(0.56±0.09)μg/cm2;5月和7月单位叶面积吸滞各粒径颗粒物的量相对最少;"串枝红"和"龙王帽"单位叶面积吸滞PM10和TSP、PM2.5和PM10、PM1.0和PM2.5之间均存在着显著的相关性,相关系数"串枝红"依次为0.9782、0.9698、0.9983,"龙王帽"依次为0.9988、0.9846、0.9953。[结论] 不同品种杏单位叶面积吸滞颗粒物能力不同,各粒径颗粒物吸滞量的变化趋势一致,"串枝红"吸滞颗粒物能力整体比"龙王帽"强,通过本研究发现经济林在提供果品的同时也发挥着重要的生态效益。

Abstract: [Objective] Two apricot of economic forest trees in Beijing was used as research materials in this study. The particulate matter adsorption capacity of economic forest trees were quantitatively analysed. [Method] Taking different apricot leaves as materials, aerosol generator(QRJZFSQ-I) was used to measure their particulate matter adsorption(PM1.0, PM2.5, PM10, TSP) capacity. [Results] Individual leaf area adsorption capacity of PM1.0, PM2.5, PM10 and TSP was different between two apricots. Individual leaf area particulate adhesion capacity of Chuan ZhiHong P. armeniaca of PM1.0, PM2.5, PM10 and TSP were 1.57, 1.72, 1.80 and 2.54 times than Long WangMao P. armeniaca respectively. Individual leaf area adsorption PM1.0, PM2.5, PM10 and TSP capacity of two apricots was the strongest in October. Chuan ZhiHong P. armeniaca were(0.87±0.09) μg/cm2,(2.02±0.008) μg/cm2,(3.90±0.07) μg/cm2 and(4.87±0.05) μg/cm, respectively. Long WangMao P. armeniaca were(0.56±0.09) μg/cm2,(1.14±0.12) μg/cm2,(2.52±0.05) μg/cm2 and(2.58±0.008) μg/cm2, respectively. Individual leaf area of adsorption amount of PM1.0, PM2.5, PM10, and TSP were relatively low in may and July. Individual leaf area of adsorption of PM10 and TSP, PM2.5 and PM10, PM2.5 and PM1.0. There was a significant correlation between Chuan ZhiHong and Long WangMao P. armeniaca. Correlation coefficient of Chuan ZhiHong P. branches 0.978 2, 0.969 8, respectively and 0.998 3 and Long WangMao P. armeniaca are 0.998 8, 0.984 6 and 0.995 3, respectively. [Conclusion] Particulate matter adsorption capacity of two apricots are different. The variation trend of different diameter particles are consistent. Particulate matter adsorption capacity of Chuan ZhiHong P. armeniaca is better than that of Long WangMao P. armeniaca. Therefore, economic forest trees can not only provide fruits but also play an important ecological function.
