| 摘 要： | 通过对太原市12个环境监测点的连续三年SO_2在大气中浓度变化分析,说明其浓度在第1.4季度呈明显高浓度,第2、3季度呈低浓度,这与绿化树木休眠期和生长期相吻合.化学分析杨树枝、叶含硫量,说明夏季叶片是吸收SO_2的主要器官,最高含硫量8.52g/kg;冬季以枝条通过韧皮部吸收SO_2,其含硫量最高值4.31g/kg;对9种绿化树熏蒸对比试验,在相同处理方式下,杨树吸硫量最高.

| Abstract: | The information about SO2 concentration in the air are analysised from 12 environment monitor sites in Taiyuan City. The SO2 concentration fluctuated with the seasons. In winter and spring, the concentration level goes in higher level than it does in summer and autumn. This phenomenon just corre-spondes with the trees' dormancy and growth. By chemical analysis, poplar leaves absorb much more SO2 and the sulfur content reaches 8. 52g/kg in the leaves. In the growth season,leaves are the main part of the tree to take in the pollution gas SO2. However, the twigs absorb SO2 mainly in the dormancy season. And the sulfur content is over 4. 31g/kg in barks. Compared with 9 other species in fumigating condition with SO2, poplar take in the harmful gas the most. Therefore, poplar plarys an important part in cleaning air in city. |
