The Soil Respiration Rate Difference of the Different Reclamation Types of Soil on the Freshwater-Wetland During the Non-Growth Season
2013
Based on a situ experiment in the Yangtze River Region, the CO2 emission flux of the natural wetland and the different reclamation types of soil during the non-growth season were investigated in this paper. The results showed that the contribution of soil respiration (SR) to the atmospheric CO2 concentration is wetland<dry land<paddy field..Furthermore, there was a significant positive correlation between the soil respiration and air temperature and soil temperature in three soil type . It concluded that reclamation of fresh water wetland significantly increased SR and soil CO2 emission from soil which was affected greatly by environmental temperature and reduced soil sequestration.
