就水位及水力负荷对湿地系统中DO质量浓度的影响进行实验。结果表明：随着水位的不断提高，芦苇湿地系统中的DO质量浓度呈现出不断升高的趋势，且在300～550 mm水位区间增加趋势比较明显，随着水位的再度升高，在550～650 mm水位区间DO质量浓度增加趋势趋于平稳；随着水力负荷的不断增加，芦苇湿地系统中的DO质量浓度呈现先增加后减小的趋势，本实验中最适合的水力负荷在0.8968～1.2230 m3/（ m2· d）之间。

In this study , the concentrations of dissolved oxygen at different water levels and different hydraulic loads were investigated through an experiment .The results show that the dissolved oxygen concentration in the Phragmites australis wetland increased with the water level , and the increasing trend was significant when the water level ranged from 300 mm to 550 mm.When the water level ranged from 550 mm to 650 mm, the dissolved oxygen concentration showed a steadily increasing trend . As the hydraulic loads increased , the dissolved oxygen concentration in the Phragmites australis wetland increase initially , and then decreased .In this experiment , the suitable hydraulic loads were between 0.896 8 and 1.223 0 m3/(m2· d).
