补充资料:坎大哈
坎大哈 Qandahār 阿富汗第二大城市,南部主要商业中心和交通重镇,坎大哈省省会。人口约21万。位于勒齐斯坦沙漠东北端海拔1000米的绿洲上。最初为亚历山大大帝所建。1221年曾遭蒙古人破坏。14世纪又遭帖木儿破坏。1522年纳入巴布尔统治。1747年成为杜伦尼王朝的首都。坎大哈周围为灌溉农田,农产品主要有小麦、羊毛和水果,为工业发展提供了丰富的原料,农产品集散于此。工业有粮食、果品加工和棉毛纺织工业。手工业以制毯著称。矿产品主要出产黄金和宝石,以此为主的手工工业也较为发达。坎大哈位于喀布尔、赫拉特以及奎达(巴基斯坦)的公路交叉点,交通地位十分重要。有国际航空港,但主要用于国内航线。城中有阿赫美德沙(杜伦尼王朝)的陵墓,旁为赫尔盖·沙里夫清真寺,内藏穆罕默德圣袍。 |
