Abstract :
The purpose of this work is to examine the effect of elevated carbon dioxide (CO2) and the relationship with wetland plant species in shallow lake wetlands in the East China. The wetland plant species such as Potamogeton crispun, Water hyacinth and Water iris were grown under two levels of CO2 in ambient and elevated (ambient CO2 + 200 μL L-1) respectively. They are grown in three replicated rooms, two for elevated and one for ambient treatment for four months individually in open top chambers. Elevated CO2 is seemed significantly responsible for changes of carbon and nitrogen cycle with the influent amount of CO2 inputs, plant situations and potentially altered C, N storage in soils. After four months experiments, the wetland plant species were died with (1) TOC and TN were changed higher and lower respectively and (2) Ammonium and Nitrate were also lower and higher respectively according to elevated CO2.
