The open to traffic of Qing-Zang railway speeds up the development of traditional culture of Tibet,and in the meanwhile,it brings along new problem and challenge to the inheriting and development of traditional culture of Tibet,and we should pay attention to it.

Several technical problems needed to be solved in development of the Qingzang railway passenger cars are analyzed, and the corresponding solution measures are discussed.

Research on the Test of Vegetation Recover in Summit Area of Tanggula Mountain along Qinghai-Tibet Railway;

The Study for Articles for Labour Protection Use of the Workers in Qinghai-Tibet Railway;

Sanitary Guarantee Strategy During Operating Period of Qinghai-Tibet Railway;

Study on the Way of Restoration and Rebilitation of Vegetation in the Hgh-altitude Area of Qinghai-Tibetan Railway;

Evaluation of Application of the Insulation to Embankment in Qinghai-Tibetan Railway;

Temperature field response of Qinghai-Tibetan Railway roadbed upon horizontalgathering and controlling nature cold energy;

Development of polyurethane coating for Qingzang railway locomotive car;

Determination of the Technical Scheme for Application of Electric Space Heaters on Qingzang Railway Passenger Cars;

Discussion of Developing Mechanical Refrigerator Cars for Qingzang Railway;

The environmental condition of the area along Qinghai Tibet railway,the permitted dioxide concentration in the railway passenger cars specified,the relationship between dioxide production rate and physical activity of human beings,and the calculation of the fresh air rate with its effect on the power consumption of the electric heater were introduced.

The environment protection work in constructiog Qinghai Tibet railway attracts worldwide attention.

According to climate and geographic conditions of Qinghai Tibet railway the analytic hierarchy process (AHP) is applied in appraising and analyzing the mechanized maintenance modes of Qinghai Tibet railway in order to acquire reasonable mechanized maintenance mode for railway.
