Abstract: Ancient Andier city is located in the hinterlands of the Taklimakan Desert near Minfeng county in Khotan, Xinjiang. Because of hazardous natural conditions, thesite shows severe deterioration from wind erosion, rain erosion, foundation recession, fractures, and being buried by sand. The physical properties of the soil in this area have been determined in laboratory tests. After investigating and analyzing the characteristics of the deterioration and local soil, this paper suggests that the following conservation measures should be taken: preventing surface weathering with PS; building adobe supports or backfilling areas suffering serious sapping erosion; and draining water away from wall bases.
Keywords: ancient Andier City; deterioration; preservation and consolidation

安迪尔古城遗址位于新疆维吾尔自治区和田地区民丰县安迪尔牧场东南约27km的沙漠腹地(图1),是丝绸之路南道汉唐时期的重要遗址,2001年6月国务院公布为第五批全国重点文物保护单位。遗址分为东、西两个区,地理坐标北纬37°26′—37°54′,东经83°32′—83°50′,海拔约1300m。东部遗址区包括夏羊塔克古城遗址、廷姆佛塔遗址、道孜勒克古城遗址、南方古城遗址以及周围的佛塔、墓葬、冶炼作坊和窑址等。根据出土文物,该区域遗址分为早、晚两个时期,早期遗址时代大概在公元1—3世纪末4世纪初,夏羊塔克古城、廷姆佛塔、道孜勒克古城下面的遗址形成一个聚落;晚期遗址主要是唐吐蕃时期(8世纪中叶),时间很短,包括道孜勒克古城及其内部佛寺,周边还分布其他遗址,包括佛塔、房屋、陶窑、冶炼遗址等。西部遗址区主要是阿其克考其克热克古城遗址。
安迪尔古城,唐以前未见正史记载,推测属扜弥国。……
