| 英文摘要 | There is sufficient evidence to support the idea that organic matter (om) in plants converts to inorganic matter during a fire. however, it is still unclear whether plant burning can also produce enough dissolved organic matter (dom) to affect the regional environment. in order to investigate this issue, we analyzed the contents of dissolved organic carbon (doc), dissolved inorganic carbon (dic) and dissolved organic nitrogen (don) in plant ash derived from simulated burning. the results showed that the ash of wetland plants contained a certain amount of dom. the doc contents in plant ash ranged from 48.6 +/- 13.1 mg.kg(-1) to 232.3 +/- 62.6 mg.kg(-1), and don contents in plant ash ranged from 18.7 +/- 3.6 mg.kg(-1) to 232.3 +/- 6.7 mg.kg(-1). in addition, the contents of doc, dic and don in ash varied with the vegetation species in wetland ecosystem. there were greater dic and don in the shrub plant ash than in the herbage plant ash, while the ratio of doc and tc was lower than in the shrub plant ash. there was a reason to believe that plant ash derived from fire did play an important role in nutrient cycling in wetland ecosystems, and dom in plant ash did contribute to the regional and global environmental changes. |
