摘要
以金叶女贞为试材,研究比较了其在不同环境条件下滞尘量的差异及蒙尘后的生理响应。结果表明:金叶女贞在所选择地点的平均单位面积滞尘量大小顺序依次为:建筑区>商业区>工业区>校园区。对叶面尘粒径分析表明,叶面尘中滞留的颗粒物中大多数是TSP,同时对PM10和PM2.5均有一定量的吸收。随着叶片蒙尘时间的延长,相对含水量出现先下降后上升的趋势,比叶重出现动态变化的趋势,脯氨酸的含量则有增加的趋势。
Taking LigustrumX vicaryi as experimental material, the effect of different environmental conditions on the dust catching quantity difference and disgraceful after physiological response were studied. The results showed that LigustrumXvicaryi in selected locations of the average unit area dust catching quantity ordered Construction areas） Commercial area Industrial areas〉 Campus area. On the surface of dust particle size analysis showed that foliar dust retention of particles in most was TSP, while PM10and PM2. s had a certain amount of absorption. As the blade disgraceful time prolonging, the relative water content appears first decreased then increased, LMA of dynamic change trend, the proline content tended to increase.
