Net CO₂ Exchange and Water Vapour Flux in Wetland Ecosystem and Their Relationship

As an important component of the terrestrial carbon cycle,carbon recycling in wetland ecosystem plays a crucial role in global change.Water vapor flux is one of the most important and the most fundamental ecological factors affecting carbon recycling in wetland ecosystem and is therefore closely related to net CO₂ exchange in wetland ecosystem.Based on summarization of the basic laws and main affecting factors of net CO₂ exchange and water vapor flux in wetland ecosystem,relationship between the two is analyzed.Macroscopically,the interaction between net CO₂ exchange and water vapor flux is determined by characteristics of the wetland ecosystem per se,and microscopically stomatal behavior on the foliage scale is the link connecting water transpiration with net CO₂ exchange.Prospects of the research is predicted.
