| 摘 要： | 利用静态箱法测定城市黑臭河道!南宁市朝阳溪夏季产甲烷通量,结果表明朝阳溪是重要的甲烷排放源,夏季甲烷排放通量平均值为12.2mg/(m2·h),上游、中游、下游排放通量变化不显著。利用偏最小二乘法进行相关性分析可得,甲烷通量与温度、化学需氧量、底泥有机碳呈显著正相关,与溶解氧呈显著负相关,与总氮、氨氮、总磷、pH相关性较小。

| Abstract: | To measure the methane flux produced by city black odor river in Summer with the usage of static box, Chaoyang Creek in Nanning City, China was studied as an important root of CH4. The average emissions of CH4 of 12.2 g/(m2·h) in Summer with little variations at different reaches were accquired. A correlation analysis using partial least square method shows that methane flux has positive correlations with temperature CODCr and sediment organic carbon, at the same time, a negative correlation with DO, and weak correlations with TN, NH4+-N, TP, and pH. |
