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.
