| 摘 要： | 介绍了20世纪70年代江源地区的测图情况,指出沱沱河正源纳钦曲是兰州军区测绘部队1974年发现并测图。论述了认定河源诸项标准的由来,指出确定河源不可随意择取认定标准和确定主次。对"三源说"提出了质疑:沱沱河源于尕恰迪如岗雪山群东南侧两初始冰川,而非姜古迪如南侧冰川;认为把楚玛尔河定为长江的北源,既不符合实际,又搞乱了水系的干支名系关系,并出现多个源头,有违发源地的地域慨念。依江源数十条源流形成的密集扇形分布水系,提出长江发源地应表述为:源于唐古拉山脉北麓。按照认定河源的诸项标准,对长江诸源进行了分析与比量,当曲各项均为最优,认为当曲才是长江正源,源于霞舍日啊巴山峰东侧的多朝能谷地。指出量算长江的精确长度,应顾及诸多因素并建议重新量算。
