【Abstract】 The paper analyzes the minimum ecological discharge for the lower reaches of the Second Songhuajiang river by using the Montana method,the most low monthly average discharge with 90%assurance rate and the flow duration curve method,analyzes the discharge flows of each month that could meet the demand of water consumption of ecological environment in the lower reaches after the completion of Hadashan hydro junction,and forecasts the specific influence of precipitation decreasing and water consumption increasing in upper reaches in future on the ecological environment of lower reaches更多还原
