In the land ecosystem, the forest can absorb the carbon dioxide (CO) in the atmosphere and turn the CO into organic carbon to store it in the plant body. About 2 × 10 tons of CO changes through photosynthesis into organic matter by plant annually. In this research, ten kinds of woody plants were selected for assessing the carbon fixation ability influenced by sulfur dioxide (SO). The tested trees were put into a fumigation chamber for 210 days in a 40-ppb SO environment. The results of this study showed that there was no clear symptom of tested trees under a 40-ppb SO environment. The tested trees could tolerate this polluted environment, but it will impact their CO absorption ability. The carbon fixation ability will reduce as the polluted period lengthens. The carbon fixation potential of tested trees ranged from 2.1 to 15.5 g·CO/m·d with an average of 7.7 g·CO/m·d. The changes in CO absorption volume for Messerschmidia argentea were more stable during the fumigation period with a variation of 102%. Among the tested trees, Diospyros morrisiana had the best carbon fixation potential of 9.19 g·CO/m·d and M. argentea had the least with 2.54 g·CO/m·d. [ABSTRACT FROM AUTHOR] |
