| 英文摘要 | The majority of rivers are a CH(4)source that accounts for an important proportion of annual global emissions. However, CH(4)evasion from urban river networks has received disproportionately less attention than their contribution. The effect of water governance on water quality and CH(4)emission in urban areas remains unclear. Water quality, CH(4)concentrations, and fluxes from a river network in Binhu District, Wuxi City, and their response to water governance were analyzed in this study. CH(4)concentrations in the investigated rivers ranged from 0.05 mu mol L(-1)to 16.37 mu mol L-1(2.47 +/- 4.5 mu mol L-1, medium 0.23 mu mol L-1), and CH(4)diffusive fluxes were 75.55 +/- 171.78 mu mol m(-2)h(-1)with a medium of 6.50 mu mol m(-2)h(-1). CH(4)concentration showed a significant correlation with water quality parameters, especially for NH3-N (r = 0.84,p< 0.001). Significant differences in water quality and CH(4)levels were found between sites that had conducted water management and those that continued to exhibit poor water quality. Our analysis showed that rivers under water governance have a positive tendency toward water ecological restoration, and a significant decrease in CH(4)efflux to the air can be achieved after extensive and intensified water governance. |
