| 摘 要： | 扬州古运河风光带绿地生态环境效应测试表明:绿地树木对空气微尘有着显著的阻挡、截留和吸滞作用,复层林分的滞尘效应优于园路近20个百分点、优于草坪10.7个百分点。绿地群落可较硬质园路区降低噪音约7dB,可较草坪区降低噪音约4dB;林带减弱噪音的效应与林分组成结构有关,一般以阔叶林减噪效果最显著,叶片大而质硬并重叠排列的树种减噪效果较好,低分枝、矮树冠乔木的减噪作用要比高分枝、高树冠的乔木明显。落叶树种的平均固碳释氧量显著高于常绿树种,且常绿乔木的平均固碳释氧能力是落叶乔木的71%、常绿灌木的平均固碳释氧能力是落叶灌木的67%;不同类型树种的平均固碳释氧能力,总体趋势为:落叶灌木 > 落叶乔木 > 常绿乔木 > 常绿灌木。

| Abstract: | Studies on environmental effects of the plants growing in the scenic areas along the Grand Canal in Yangzhou indicated that: plants had signif icant effect on dust blocking, holding and absorbing. The dust blocking ability of multi-layer forest was nearly 20 percent higher than that of garden road, and 10.7 percenthigher than that of lawns. The green area could reduce the noise by about 7dB than the garden road, and the broad-leaved forests were the best. Trees with large, hard and overlapping leaves were b... |
