摘　　要：SL/Z 712-2014规范中推荐的排频法、历时曲线法、蒙大拿法等计算方法,对某一河流来说,可能是方法甲的计算成果较合适;而对另一条河流来说,可能是方法乙的计算成果更合适。显然,各种方法各有其优缺点和优势,因此,在实际的工作中,不能简单地下结论为哪一种方法好,而各种方法在实际的应用过程中,优势互补,取长补短,相互验证,并且多种方法的计算成果,经代表性、合理性、可靠性等综合比较后,合理选定符合目标河流实际情况的方法为好。The calculation methods recommended in SL/Z 7122014,such as frequency order method,duration curve method and Montana method,the calculation results of method A may be more suitable for a certain river;however,for the other river,method B might be more suitable.Obviously,each method has its own advantages and disadvantages.Therefore,in practical work,it shouldn't conclude simply which method is better.During the course of actual application of each method,various methods should complement each other's advantages,learn from each other's strengths and verify them mutually.Besides,after comprehensive comparison of the calculation results of various methods,such as representativeness,rationality and reliability,it is better to choose a reasonable method to match the actual situation of the target river.
