摘要: 为了研究在单株尺度上林木对大气中不同颗粒物的阻滞作用,选择圆柏作为研究对象,分析3个树冠高度和不同季节中PM2.5、PM10以及TSP这3种颗粒物的浓度变化规律;对圆柏不同高度上的阻滞效率进行探究,并使用离子色谱对PM2.5颗粒中的6种水溶性离子成分进行分析。结果表明:不同高度上浓度日变化规律大致相同,浓度差异不大,并均在中午达到最低值;但3个高度的阻滞率差异悬殊,以中部阻滞效果最为明显,尤以PM2.5为甚,可达47.6%,其次是上部,下部最低;3个季节浓度相差较大,春季最高,夏季次之,秋季最低,且以秋季的波动最为平缓;水溶性离子浓度以Na 、NH4 最高,圆柏对F-、Na 阻滞效果明显,分别为87.62%、68.27%。

Abstract: The paper aims to research the ability of the individual tree to intercept atmospheric particulate matter. The authors analyzed the change rule of atmospheric particulate matter, such as PM2.5, PM10 and TSP in different heights of the tree crown of Sabina chinensis as well as different seasons, and evaluated the block effect of 3 heights of Sabina chinensis and analyzed 6 soluble ions of PM2.5 by IC (ion chromatography). The results indicated that: there were similar change rules of atmospheric particulate matter in different heights and all showed the minimum at noon, however, the block effect rate of 3 heights had great disparities and the maximum appeared in the middle part, especially on PM2.5 and the efficiency could reach 47.6%, then followed by the upper part, and the under part was the lowest; comparing different seasons, spring showed the highest concentration, followed by summer, while autumn showed the lowest concentration, what’s more, the gentlest fluctuation also appeared in autumn; Na and NH4 were at the highest concentration of soluble ions and Sabina chinensis was effective at blocking F- and Na , the efficiency was 87.62% and 68.27%, respectively.
