7、民和县、乐都县、平安县至青海省会西宁，后折向北经大通县、门源县，穿越祁连山山脉进入甘肃省河西走廊西行，经民乐县、张掖市、临泽县、酒泉市、嘉峪关市、玉门市以及新疆自治区哈密市、鄯善县、吐鲁番市，西至新疆维吾尔自治区首府乌鲁木齐市。（二）主要自然特征本线线路长，由于其特殊的地理位置和特殊的气侯条件，线路经过地区工程地质问题与其它地区有所不同，大风形成的风害成为本线最为特殊、关键的问题。本线跨越二省一自治区，沿线气候也有较大差异，但其共同特点是气候干燥，旱季长、雨季短，降雨量较少切集中，昼夜温差变化较大，春、秋季多风，夏季短促，冬季寒冷。年平

8、均气温1.8°（门源）～14.0°（吐鲁番），极端最高气温31.3°（达坂城）～47.7°（吐鲁番），极端最低气温－21.7°（兰州）～－41.5°（乌鲁木齐），年平均降雨量16.2mm（吐鲁番）～530m
