　　自古以来中国的云南省以马帮运输茶、盐、粮食的古道已有近千年的历史。马帮就像今日的汽车，在山路中将背上的货物运往各地。“茶马古道”也因此而得名。茶马古道穿越中国西南地区的四川和云南省一直到西藏地区，尼泊尔和印度。古道不仅是最重要的商贸通道，也是中国内陆和西藏地区语言、人口、宗教和文化交流的重要通道。

　　茶马古道是一个非常特殊的地域称谓，是一条世界上自然风光最壮观，文化最为神秘的旅游绝品线路，它蕴藏着开发不尽的文化遗产。滇藏茶马古道大约形成于公元六世纪后期，它南起云南茶叶主产区思茅、普洱，中间经过今天的大理白族自治州和丽江地区、香格里拉进入西藏，直达拉萨。有的还从西藏转口印度、尼泊尔，是古代中国与南亚地区一条重要的贸易通道。普洱是茶马古道上独具优势的货物产地和中转集散地，具有着悠久的茶马古道地图历史。
