- 摘要:
- 以龙爪槐(Sophora japonica var.pendula）、金银花(Lonicera japonica ）、洋白蜡(Fraxinus chinensis）、枫杨(Pterocarya stenoptera）、二乔玉兰(Magnolia×Soulangeana）、桑树(Morus alba）和银杏(Ginkgo biloba）为研究对象，采用洗脱法对7种园林树木单位面积的叶片吸附总颗粒物和PM2.5能力进行了测定，并测定了7种树木叶片滞尘前后叶片脯氨酸含量的变化，以研究不同种树木叶片滞尘效应，以及叶片滞尘后对植物生理活动的影响。结果表明：不同树种单位面积的滞尘量不同，银杏滞尘量较高，为0.034 mg?cm-2，桑滞尘量仅有0.010 mg?cm-2。叶片滞尘之后，银杏、枫杨、龙爪槐、桑、二乔玉兰叶片脯氨酸含量均有21.73%~338.25%等不同程度的升高，脯氨酸增长量由大到小排列为银杏、枫杨、龙爪槐、桑、二乔玉兰；而金银花和洋白蜡叶片脯氨酸含量不升反降，洋白蜡降低了59.77%，金银花降低了66.14%。综上说明银杏滞尘(PM>2.5)能力最强，桑滞尘(PM>2.5)最弱。
- Abstract:
- Taking the leaves of Sophora japonica var.pendula,Lonicera japonica,Fraxinus chinensis,Pterocarya stenoptera,Magnolia×Soulangeana,Morus alba,Ginkgo biloba as test materials,the effect of the dusty leaves′s physiological activities was studied,the captured amount of TSP and PM2.5 per unit leaf area for seven trees were measured by water washing method.In the same time,the proline content change was measured between seven kinds of trees before and after the dust retention.The results showed that the dust retention amount per unit leaf area of different tree species was different,such as Ginkgo biloba,the higher amount dust retention per unit area of the trees′ leaves was 0.034 mg?cm-2,such as Morus alba,the lower amount dust retention per unit area of the trees′ leaves was only 0.010 mg?cm-2.Among Ginkgo biloba, Pterocarya stenoptera, Sophora japonica var.pendula,Morus alba, Magnolia×Soulangeana, the proline content in leaves was different degree in increase with the variation ranges of 21.73%-338.25%.The growth of proline had ranged from large to small,Ginkgo biloba,Pterocarya stenoptera,Sophora japonica var.pendula,Morus alba,Magnolia×Soulangeana；but Fraxinus chinensis and Lonicera japonica,the proline content in leaves declined,the content of reduction was 59.77%,66.14%.So Ginkgo biloba was the highest ability of dust retention(PM>2.5). Morus alba was the weakest ability of dust retention(PM>2.5).
