甘肃河西在古代曾经以其连结中西的地理位置,宜耕宜牧的自然条件,多民族杂居的政治因素,吸引着历代统治者对之开发经营。汉唐在中国历史上是最强盛的两个王朝,同时也是开发河西最有成效的王朝。总结这两个朝代开发河西的主要经验,比较其异同得失,对我们今天进一步开发河西不无借鉴作用。 In ancient times, Hexi, Gansu, once used its geographical position as a link between China and the West, the natural conditions of Yiling to Yichang and the political factors of multi-ethnic groups and mixed dwellings, which drew the rulers of various dynasties to develop and manage them. The Han and Tang dynasties were the two most prosperous dynasties in Chinese history and the most productive dynasty to develop Hexi. To summarize the main experiences of these two dynasties in developing Hexi and compare their gains and losses, we can learn from the further development of Hexi today.
