摘　　要：通过室内模型试验,结合理论分析,研究城市河道在i=1‰坡度不同流量下溶解氧的分布特征,给出了溶解氧含量的沿程断面分布的等值线图,详细阐述了溶解氧在江心洲处的分布规律,进一步研究了江心洲与全坝以及江心洲与开口坝在城市河道中对溶解氧含量分布的影响,研究结论为洲滩演变与河道治理提供理论指导。With the indoor model experiment and through theoretical analysis ,the distribution char-acteristics of dissolved oxygen under different flow rate in the slope of the 1‰ are studied.After drawing the distribution isoline of along the cross -sectional distribution of dissolved oxygen ,the dis-tribution disciplinarian of dissolved oxygen at river island is expatiated.The influencing factors of riv-er island as well as dam and river island with opening a dam , on dissolved oxygen content distribution are analyzed systematically.The conclusion provides theoretical guidance for the evolution of river is-land and river training.
