THE SPACE-TIME EVOLVEMENT STUDY ON SUPERSATURATION OF DISSOLVED OXYGEN IN THE MIDDLE REACHES OF THE YANGTZE RIVER
In order to analyze the ecological effects of gas supersaturation by the Three Gorges Dam and Gezhouba Dam in the middle reaches of the Yangtze River，according to the observed data，this paper applied MIKE 11 software to establish a mathematical model of dissolved oxygen in the middle reaches of the Yangtze River.Using this model，the space-time evolvement of supersaturation of dissolved oxygen in the middle reaches of the Yangtze River was simulated and predicted.The results show that the influence scope of supersaturation of dissolved oxygen is very wide and its restoration is very slow.In allusion to the prediction of supersaturation of dissolved oxygen，this paper briefly analyzed the effects of supersaturation of dissolved oxygen on fish and its mitigation measures.
