　Qinghai-Tibet railway

　　The QinghaiXizang railway, Qingzang railway, or QinghaiTibet railway, is a high-elevation railway that connects Xining, Qinghai Province, to Lhasa, Tibet Autonomous Region, in Peoples Republic of China.

　　The total length of Qingzang railway is 1956 km . Construction of the 815 km section between Xining and Golmud was completed by 1984. The 1142 km section between Golmud and Lhasa was inaugurated on 1 July 2006 by president Hu Jintao: the first two passenger trains were Qing 1 from Golmud to Lhasa, and Zang 2 from Lhasa.This railway is the first to connect the Tibet Autonomous Region to any other province, which, due to its elevation and terrain, is the last province-level entity in Chinese mainland to have a conventional railway. Testing of the line and equipment started on 1 May 2006. Passenger trains run from Beijing, Chengdu, Chongqing, Guangzhou, Shanghai, Xining and Lanzhou.

　　The line includes the Tanggula Pass, which, at 5,072 m above sea level, is the worlds highest rail track. The 1,338 m Fenghuoshan tunnel is the highest rail tunnel in the world at 4,905 m above sea level. The 4,010-m Guanjiao tunnel is the longest tunnel from Xining to Golmod and the 3,345-m Yangbajing tunnel is the longest tunnel from Golmod to Lhasa. More than 960 km, or over 80% of the Golmud-Lhasa section, is at an elevation of more than 4,000 m. There are 675 bridges, totalling 159.88 km, and about 550 km of the railway is laid on permafrost.

　　Economic and environmental impact

　　With limited industrial capacity in Tibet, the Tibetan economy heavily relies on industrial products from more developed parts of China. Transport of goods in and out of Tibet was mostly through the Qingzang Highway connecting Tibet to the adjacent Qinghai province, which was built in the early 1950s. The length and terrain have limited the capacity of the highway, with less than 1 million tons of goods transported each year. With the construction of the Qingzang railway, the cost of transportation of both passengers and goods should be greatly reduced, allowing for an increase in volumethe cost per tonne-kilometer will be reduced from 0.38 RMB to 0.12 RMB. It is projected that by 2010, 2.8 million tons will be carried to and from Tibet, with over 75% carried by the railway.This is expected to help support the Tibetan economy.

　　The environmental impact of the new railway is an ongoing concern. The increase in passenger traffic will result in greater tourism and economic activity on the Tibetan Plateau.

　　Wood is the main fuel source for rural inhabitants in certain regions of Tibet. The damage to the ecosystem caused by cutting trees for fuel takes years to recover due to slow growth caused by Tibets harsh environmental conditions. The railway would make coal, which is not produced in Tibet, an affordable replacement. However, the increase in fuel combustion due to increased human activity in an already-thin atmosphere may affect the long term health of the local population.

　　Before the railway, the purchasing power of 100 RMB in Lhasa was only commensurate with 54 RMB in coastal regions of China mainly due to high transport costs, the railway could elevate the living standards along the railway.

　　Trash and excrement are collected into two sealed containers in each car , they are taken out at the big stations.

　　The effects of this railway on wild animals such as Tibetan antelope and plants are currently unknown. Thirty-three overpasses were constructed specifically to allow continued animal migration. Here is the Google Maps satellite image of one such bridge.

　　There are concerns from the China Meteorological Administration that melting of permafrost caused by global warming in Tibet on which part of the railway is placed could threaten the railway during the century.

　　The highest railway in the world ,due to begin test runs in July 2006,crosses the famously bleak Tanggula Pass in western China to connect the Tibetan capital of Lhasa with Golmud in Qinghai.

　　The highest point of Qinghai-Tibet railway tops 5000m the highest railway. the government says the railway will bring prosperity to isolated Tibetans. Tibetans say it will serve merely as a means of carting off the region s mineral riches and ,perhaps more worryingly, of bringing in soldiers.

　　Environmentalists, meanwhile, fret about the railways impact on the fragile ecosystem of the Tibetan plateau. This is the source of Chinas five major river systems and home to several rare species including the Tibetan antelope.

　　To avoid disturbing the local animal habitation, 25 special routeways are built for wildlife move in the nature reserves including Keke Xili and Three Rivers Nature Reserve which Qinghai-Tibet Railway run through, especially for the Tibetan antelopes. These routeways show diversity according to the habits of Tibetan antelopes. Holes under the railway are for child antelopes passing by. Even bridges covered with greensward are put up the railway, just like man-made hillsides for Tibetan antelopes migration.

　　青藏鐵路

　　青藏鐵路于2001 年6 月29 日開工，于2006 年7 月1 日正式通車運營。

　　青藏鐵路，是實施西部大開發戰略的標志性工程，是中國新世紀四大工程之一。該路東起青海西寧，西至拉薩，全長1956公里。其中，西寧至格爾木段814公里已于1979年鋪通，1984年投入運營。青藏鐵路格爾木至拉薩段，北起青海省格爾木市，經納赤臺、五道梁、沱沱河、雁石坪，翻越唐古拉山，再經西藏自治區安多、那曲、當雄、羊八井，至拉薩，全長1142公里。其中新建線路1110公里，于2001年6月29日正式開工。青藏鐵路是世界海拔最高、線路最長的高原鐵路。

　　青藏高原素有世界屋脊、地球第三極之稱，是我國的江河源。在青藏高原這種原始、獨特、脆弱、敏感的地理生態環境中修建的青藏鐵路是世界上海拔最高、線路最長的高原鐵路，翻越唐古拉山的鐵路最高點海拔5072 米，經過海拔4000 米以上地段960 公里，連續多年凍土區550 公里以上。在青藏鐵路建設和施工中有效地保護生態環境，是青藏鐵路建設的重要任務，也是國內外關注的焦點。黨中央、國務院對青藏鐵路建設的生態環境保護問題極為重視。朱镕基同志要求一定要認真貫徹國務院有關加強保護青藏高原生態環境的精神，十分愛護青海、西藏的生態環境，十分愛護青海、西藏的一草一木，精心保護我們祖國的每一寸綠地。為搞好青藏鐵路建設的生態環境保護工作指明了方向。

　　經濟和文化意義

　　青藏鐵路全線貫通，必將對改變青藏高原貧困落后面貌，增進各民族團結進步和共同繁榮，促進青海與西藏經濟社會又快又好發展產生廣泛而深遠的影響。有利于促進西藏工業、旅游業等產業的發展，優化西藏的產業結構，實現我國地區經濟的平衡、協調發展;有利于西藏礦產資源的開發，發揮資源優勢;有利于降低進出西藏貨物的運輸成本，提高經濟效益;有利于西藏的對外開放，加強與其他地區及國外的經濟交流與合作;有利于西藏市場機制的發育和人們市場意識的增強，促進經濟的發展;有利于西藏人民生活水平的提高和全國人民的共同富裕。有利于促進我國各民族的共同繁榮，進一步鞏固平等團結互助的新型民族關系;有利于我國邊疆的穩定和國防的加強;有利于少數民族人民當家作主地位的體現和國家政權的鞏固。 所以修建鐵路首要的目的就是要為西藏的經濟社會發展提供一個強大的運力支持，同時這一條鐵路建設也可以使我們進一步增加內地和西藏緊密的聯系和交流，增強民族團結，保衛國土安全。

　　發揮青藏鐵路的作用，打造成國內一流的物流中心。加緊研究青藏鐵路通車運營后給西藏經濟社會生活各方面帶來的深刻影響，用全新的思路謀劃發展，最大限度地挖掘青藏鐵路的巨大發展潛力，最大限度地發揮青藏鐵路的強大輻射作用，使青藏鐵路更好地為促進西藏經濟社會發展、造福西藏各族群眾，努力將那曲物流中心打造成國內一流的物流中心。西藏有豐富的旅游、礦產、水利等資源，青藏鐵路的建成和通車，便利了游客進藏和西藏的資源開發，對于擴大旅游創匯、資源開發利用有重大的意義。

　　以上就是關于青藏鐵路的SAT寫作例子的全部內容，非常詳細。大家可以在備考自己的SAT寫作考試的時候，對此加以適當的參考和借鑒，以便更好的應用到自己的文章中去。
