Based on an analysis of the contradiction betw een time consumption and global convergence, it is considered that the genetic algorithm is much more suitable for the optimization problem diff icult to be solved by the conventional method, and the rea-l time reservoir operation problem w ith low requirement for time- effectiveness of calculation and low complexity in objective function calculation. Moreover, the genetic algorithm is especially suitable for middle- and long- term reservoir operation and planning for w ater resources. Key words: reservoir operation ; ge
