Preliminary Study on Greenhouse Gas Content in Shaying River and the Contribution of Sediment
摘要
Abstract
Measurements and an in⁃situ incubation and was conducted in Shaying River, in which nitrogen pollution was serious and organic carbon was high. The results show that the concentrations of CO2 , CH4 and N2 O are 398.8-1 052.2, 0.263 5-4.020 5 and 0.013 1-0.070 3μmol/L respectively. Comparing to the greenhouse gas content in other rivers in the world, the CO2 and N2 O concentration in Shaying River belong to above average level, CH4 concentration is at a higher level. Diel variations show that, CO2 content in the daytime is significant lower than that at night, while the content of CH4 and N2 O demonstrates no differences between that in the daytime and at night. The environmental factors have no apparent effect to the CO2 concentration; while the CH4 concentration is mainly controlled by DO. N2 O concentration in Shaying River is mainly effected by DO and TN. Sediment is an important source to CO2 and N2 O, but its contribution ratio to CO2 and N2 O is 16.52% and 9.40% respectively, which demonstrates that there are other important sources to CO2 and N2 O in Shaying River;while the sediment is the main source of CH4 and its contribution is 78.83%.关键词
