川藏线,是连通四川成都与西藏拉萨之间的公路,有南线和北线之分。骑行者口中的川藏线多为南线,相对北线而言,南线路况较好,风光也更为秀美,经过的地方也多为人口稠密的地方,路上补给比较方便,更适合骑行。 Sichuan-Tibet line, which connects the highway between Chengdu, Sichuan and Lhasa, Tibet, is divided between the southern and northern lines. Most of the Sichuan-Tibet lines in the mouth of the cyclists are the southern line. As far as the north line is concerned, the southern route is in a better condition and the scenery is more beautiful. The passing places are mostly densely populated places, and the supply on the road is more convenient and more suitable for riding .
