| 摘 要： | 于水稻生长季进行室外盆栽试验,人工模拟UV-B辐射增强20%,采用静态箱-气相色谱法测定稻田生态系统的呼吸速率、CH4和N2O排放通量,研究UV-B辐射增强对稻田生态系统呼吸速率、CH4和N2O排放通量的影响.结果表明,UV-B辐射增强没有改变稻田呼吸速率、CH4和N2O排放通量的季节变化规律;与对照相比,平均呼吸速率...

| Abstract: | To investigate the impacts of enhanced UV-B radiation on respiration rate,CH4 and N2 O emission fluxes from soil-rice system,outdoor pot experiment was carried out during the rice growing season in 2004.The enhanced UV-B radiation treatments were simulated by a 20% increase in its intensity.The gas emission fluxes were measured by static chamber-gas chromatograph method.Results showed that enhanced UV-B radiation(T) did not change the seasonal patterns of respiration rate,CH4 and N2 O emission.Compared to t... |
