正确答案Qinghai-Tibet railway (or Qingzang railway) is completed from a long-term closed state bringing the continuous economic development in Tibet. Retarded mindset which is caused by traffic blocking or inaccessibility is a significant factor of backward economic development in Tibet.The unique geographical location of Tibet results in its long-term external dependence of economic development. Due to the limited capacity of transportation in the existing roads and the relatively high transportation cost, the internal and external exchange of goods is impossible to have a substantial increase whereby it is no doubt limiting the momentum of economic growth in Tibet. 1. Qinghai-Tibet railway is completed which causes a reduction in transportation costs and it is conducive to the internal and external exchange of goods:Animal husbandry has been vigorously developed.Animal husbandry in grassland is the basis and pillar industries in Tibet which includes the natural grassland and yak, Tibetan sheep, Cashmere goats, pigs, Tibetan chicken and other poultry.Mineral resources have been greatly developed. Tibet has a vast territory which is rich in mineral resources especially a variety of first-ranked metallic minerals in the world. Therefore, the completion of Qinghai-Tibet railway creates good conditions for the development of animal husbandry and mineral resources. Meanwhile, it may contribute to a reduction in regional differences of the level of economic development in Tibet. 2. It is beneficial to the tourism industry in Tibet.Tibet is rich in tourism resources which is beneficial from its unique geographical location and religious culture. Tibet is not only located at the highest plateau of the altitude in the world, but also it is located at the intersection of the Chinese, Indian and European civilizations.In the decline of Babylonian, Persian and Roman Empire and other ancient empires which have glorious histories in the world, Tibet is still standing firmly. It makes the world feel its mysterious power and also the beautiful natural scenery which is basically not been industrial polluted. Tourism industry in Tibet is therefore having great prospects of development. Accelerating the economic construction in Tibet is to protect the safeguard of China unification. Tibet is located in the periphery of China which is a very important strategic position. China is currently having the problem which requires a stable political environment. The fundamental means in consolidating the national defence and achieving the national stability are to accelerate the economic and cultural development of border areas. These can be established only with economic development which brings the prosperity to the people. Bad effects Impact on the environmentThe natural resources in Tibet are precious because it is less influenced by human destruction. Although the development of Tibet emphasizes the balance and the coordination of the Tibetan environment and tourism establishment, it still destroys the natural environment of Tibet. Impact on the religionMost of the people in Tibet Autonomous Region (or Xizang Autonomous Region) are religious and there are often religious issues related to the national problems. Besides, the religion in Tibet is equivalent to the role of school whereby one must become a monk in order to learn the culture education in a monastery. The development of Tibet has weakened the influence of religion and thus a series of bloody conflict has occurred due to it has been deliberately incited.用了很多时间翻译。希望你会满意。请评分与采纳。谢谢。
