城址遗存与汉代西域屯城布局

The remains of the site the layout of the defense cities of the Han dynasty in the Western Regions

屯城是两汉经略西域的重要军事据点,在两汉不同时期,随着中原王朝西域战略的变化,西域屯城布局也随之相应变化。西汉西域屯城主要布局于天山南麓的轮台、渠犁、焉耆、龟兹、伊循、楼兰及靠近匈奴的车师前国;东汉则侧重于伊吾、柳中、高昌、楼兰等汉匈对峙的前沿地域,以及汉匈对峙外缘的昆仑山南麓疏勒、于阗、精绝等地,从而使两汉的屯城布局由最初在天山南麓、东麓重要区域的点状、线状布局,进而呈现出在环塔里木盆地周缘环状布局的态势,一定程度上体现了两汉治理西域的策略,经历了一个从初始探索到逐渐成熟的历史进程。
