这些高原牧人,远离家园的感受又是什么?在如此广袤的草原上,那些牛羊和牧人,实在屈指可数,他们的存在,究竟是守护了这片高原的环境,还是破坏了生态?应该并非非此即彼,而是个值得探究的问题。在长江三源中,长江南源当曲是长度最长的一条,隔几年就出现一下与格拉丹东何为长江正源的争论。对此,中科院刘少创博士认为,这一问题其实很简单,最长的比如当曲叫做地理源头,格拉丹东那样的叫做文化源头就好了。 What are the feelings of these plateau herders far away from their homeland? There are really a handful of cattle, sheep and shepherds on such a vast grassland. Does their existence guard the environment of this plateau or destroy the ecology? It is not a question of both, but a question worth exploring. Among the three sources of the Yangtze River, the southern part of the Yangtze River is the longest one, with the debate over what will be the east of the Yangtze River. In this regard, Chinese Academy of Sciences Dr. Liu Shao-chung believes that this issue is actually very simple, the longest, such as when the song is called the geographical source, as the cultural source called Gladan East just fine.
