西气东输工程线路踏勘

The Route Survey of the China's West-to-East Gas Pipeline

西气东输工程线路西起新疆轮台县的轮南首站，东抵上海青浦县的白鹤末站，途经新疆、甘肃、宁夏、陕西、山西、河南、安徽、江苏、上海，线路全长约4 000 km。根据管线走向和沿途地形地貌特点将线路划分成4段，通过对每一段的线路长度、地形地貌、工程地质、地区等级、交通条件、线路投资、管道施工和维护管理等方面进行比选，得出了目前西气东输管道线路的推荐方案。

The China's West-to-East Gas Pipeline starts from the Lunnan head station in Lunnan County of Xinjiang Province and runs eastward to the Baihe end station in Qingpu County of Shanghai City by way of Xinjiang, Gansu, Ningxia, Shaanxi, Shanxi, Henan, Anhui, Jiangsu, Shanghai with overall length about 4000 km. On the basis of pipeline route and terrain characteristics the whole pipeline is divided into four sections. For each section there have been compared length, terrain, engineering geology, category of district, traffic condition, pipeline investment, construction, maintenance and management etc. and worked out the current proposed route case of the China's West-to-East Gas Pipeline.
