| 摘 要： | 树木主要通过气孔吸收气态污染物,同时通过滞留空气中的微粒而减轻污染,树木较高的覆盖率可能会减少挥发性有机物的释放量,定量研究表明,合肥市1998年吸收空气污染物约为151.5t,树木7月份(着叶季节)吸收污染量高达20t,具有相对较低臭氧生成潜力的植物有香樟属、女贞属、紫薇属、罗汉松属和李属。合肥城市森林总体的臭氧指标得分值为92.4。

| Abstract: | Urban forest structure and its effect on air quality were assessed for downtown of Hefei city,the study area covers 23 km2. The area has 351,542 trees (25% tree cover), with Chinese Privet, Dawn Redwood, and Deodar Cedar are the most common species. Pollution removal by these trees in 1998 is estimated at 169 tons (32.3 g/m-2 tree cover) with a value of $785, 000 in Hefei,. Large individual trees (38.1 -45.7 cm dbh) are estimated to remove 2.76 kg of pollution per year with a value of $12. 84. Some common genera that have relatively low volatile organic compound emissions and therefore low ozone forming potential include Cinnamomum, Ligustrum, Lagerstroemia, Podocarpus and Prunus. The effects of current and future urban forest management to improve air quality in Chinese cities are discussed. |
