Diurnal methane flux across water-air interface in summer in Nihe reservoir
摘要
Abstract
In order to study diurnal methane emission of irrigated reservoir in northeast China, Static floating chamber methods were used to measure methane flux across water-air interface in Nihe reservoir in July 2008. The results indicated that the mean methane flux of Nihe reservoir was 13.48 mg/(m2 · H) in summer; the lowest emission occurred at night (21:00) and the emission peak observed at day (5:00 and 9:00). There was significant difference between different time of day (P <0.05) and the methane flux at 21:00 was significantly lower than that of at 5 :00 and 9:00. There was no significant difference in outlet, center and outlet of reservoir. Correlation analysis showed that methane flux was positive relation significantly with total nitrogen (P <0.05 ) , and there were no significant relation with other environmental factors including air temperature, water temperature, total organic carbon , dissolved organic carbon, total phosphoric, water depth, wind speed and dissolved oxygen.关键词
