亿万年前,青藏高原在漫长的地质历史时期曾是古地中海的一部分。7000万年前,印度板块向北漂移,与欧亚大陆碰撞、俯冲,在漫长的喜马拉雅造山运动中,海水向南退缩,一片神秘的陆地渐渐隆起抬升,形成了世界上最高、最年轻的陆地——青藏高原。青藏高原是地球上独一无二的高度大、地壳厚的地区(地壳厚度达50-70公里),是大陆对大陆间大规模相向碰撞而隆起抬升的典型。青藏高原雄踞亚洲大陆中部,总面积295万平方公里,号称“世界屋脊”、地球“第三极”,是世界最高的山地高原,平均海拔4000米以上。从公元7世纪文成公主进藏、13世纪中叶元代西藏正式列入中国版图以来,这块人迹罕至的雪域高原一直呼唤着高山峡谷架“金桥”,千百年来,藏族人民企盼高原变通途的歌谣就有400多首。值得庆幸的是,这千百年来的历史宏愿即将成为现实——青藏铁路将于2006年7月1日投入试运营。摄影师张立明于铁路建设一始就用手中的相机记录着铁路的延伸、记录着建设者的风采、见证着这一千古奇迹的诞生。他平凡、认真、执著,但伟大就此被抒写。
Hundreds of millions of years ago, the Qinghai-Tibet Plateau was a part of the ancient Mediterranean in the long geological history. 70 million years ago, the Indian plate drifted northward and collided with the Eurasian continent. During the long Himalayan orogeny, the sea shrank southward. A mysterious land gradually rose and lifted to form the tallest and youngest land in the world - Qinghai-Tibet Plateau. The Qinghai-Tibet Plateau is unique in the earth with large and thick crustal areas (crust thickness of 50-70 km), and is a typical example of the uplift of the mainland by large-scale collisions with the mainland. The Qinghai-Tibet Plateau occupies the central part of the Asian continent with a total area of 2.95 million square kilometers. It is called “the roof of the world” and the “third pole” of the earth. It is the highest mountain plateau in the world with an average altitude of over 4,000 meters. Since the seventh century, when Princess Wencheng entered Tibet and Tibet was formally included in the territory of China in the mid-13th century, this inaccessible snow-covered plateau has always called for the “Golden Bridge” in the mountain canyon. For thousands of years, the Tibetan people have been looking forward to plateau changes There are more than 400 ballads. Thankfully, the historical ambitions for thousands of years are about to become a reality - the Qinghai-Tibet Railway will be put into trial operation on July 1, 2006. Photographer Zhang Liming at the beginning of the construction of the railway records the extension of the railway with the camera in hand, recording the builders’ style and witnessing the birth of this ancient miracle. He is ordinary, serious, persistent, but the great was described.
