There are Tibetan antelopes (藏羚羊) , which live on the Qinghai-Tibet
plateau (高原) have been used to the high speed trains flying by above them.
"The heavy use of the underpasses (铁路下过路口 )shows the animals'
migration (迁徙)habits have not been affected by the railway," said Yang Qisen,
who has been studying the railway's impact (影响) on wildlife since it opened
five years ago.
Yang, who is a researcher with the Institute of Zoology under the
Chinese Academy of Sciences (中科院动物研究厅), said a group of 3,000
antelopes live mostly in eastern Qinghai Province. However, every June, some
of them migrate to the Kekexili region of western Qinghai and northeastern Tibet
to give birth to their young.
The animals make their return journey in August, which means they pass
under the railway twice a year, he said.
For the past five years, between June and September, Yang and his team
have stayed near the railway to find out what it had done on local wildlife. They
have paid close attention to the migration patterns of the antelopes.
In 2004, 96 percent of the migrating antelopes were seen using the
underpasses. After 2005, the figure rose to 98 percent, Yang said.
