The Adaptability Of Tibetan Antelopes On The Qinghai-tibet Railway Wildlife Passageways Through The Channel Behavior Studies

Hohxil is one of the habitats of the Tibetan antelope,which faces the danger of extinction and is under the State's first-grade protection.In June and July each year,they form groups and travel long distances to Zhoine and Taiyang lakes to breed.The wildlife passageway of Qinghai-Tibetan railway is the most important factors of human interference of the Tibetan antelope migratory journey.In this study,the Tibetan Antelope' classification,feeding habits and feeding behavior,population status,breeding and migration behavior,distribution and quantity,and status of conservation et,were introduced by long term investigation.The utilization of the wildlife passageways,which were founded of the establishment of Qinghai-Tibetan railway,was investigated.The behavior of Tibetan antelope which crossing the wildlife passageways of Qinghai-Tibetan railway in summer was researched.The utilization of 33 wildlife passageways,which were founded of the establishment of Qinghai-Tibetan railway,were investigated by automatic camera monitoring,dynamic monitoring and pinpoint monitoring between 2004s and 2007s.The result showed that only 7 wildlife passageways were used by Tibetan antelope of 33 wildlife passageways and demonstrated that the time of the Tibetan antelope's crossed the wildlife passageway of Qinghai-Tibetan railway had been moved up,the amounts of Tibetan antelope that crossed the wildlife passageway,were increased year by year.It means that the utilization of the wildlife passageway was increased obviously.The month of August and September in every year of 2004s to 2007s,during the period of moving back of Tibetan antelope,we used the focal animal method and th e video recording writing method to research the behavior of Tibetan antelope who cr ossing the wildlife passageways of Qinghai-Tibetan railway in summer.Found 5 kinds of types of time assignment behaviors of Tibetan antelope,which were Foraging,Vig ilance,Resting,Moving and "Others",besides those were changed with the Tibetan an telope passing through activity.Before passing through the wildlife passageways and a way from the passageways more than 1000m,5 types of time assignment behaviors' pr oportion respectively were 59.0%,8.9%,19.6%,11.2%,1.6%;about 500m away form the passageways the proportion were 17.1%,20.1%,2.1%,59.0%,1.7%;In the sa me way when the distance less than 100m the result were 10.5%,69.0%,0.7%,18. 3%,1.5%,it showed that Tibetan antelope's behavior time assignment of Vigilance and Moving were obviously lifting(P＜0.01) before they crossed the wildlife passageways. Foraging and Lying behavior time assignment had obviously decreased(P＜0.01)."Oth ers" behavior were not difference(P＞0.05);When the distance was less than 100m,abo ut 500m and more than 1000m after Tibetan antelope crossed the wildlife passageways, the evolution results showed that:there was no difference(P＞0.05)of Foraging,Vigila nce and "Others" behavior time assignment of Tibetan antelope.Lying and Moving be havior time assignment were obviously different(P＜0.05).Before passing through the wildlife passageways and away from the passageways more than 1000m,5 types of ti me assignment behaviors' proportion respectively were no difference(P＞0.05) from pas sed through.Anyway,Tibetan antelope could habituate themselves to the changes of s urroundings owing to the Qinghai-Tibetan railway passageways building by learning an d adjusting their behavior.
