摘要: Because of the global warming and the increasing human activity, the air temperature and the precipitation along the Qinghai-Tibet Railway increased gradually in recent years, which endanger the permafrost table, the embankment of the railway. The statistics of the air temperature, the precipitation and the geothermal temperature in recent 50 years in this dissertation come from the four weather station along the railway, that are Wudaoliang Station, Fenghuo Mountains Station, Tuotuo River Station and Ando Station. This dissertation analyzes the change of climate along the railway and then develops a research on the effect of the changing geothermal temperature on permafrost table and its countermeasures. The experiment result shows that the air temperature of the permafrost region rise steadily in about 50 years, especially in this century, the tendency of rising temperature is more obvious. The precipitation fluctuates but it is also rising rapidly, for the largest precipitation reached 492.6 mm. For 30 years now, the Qinghai-Tibet Plateau has been in the megathermal period, which also affects the permafrost region along the railway. The condition of permafrost is degrading greatly.

This dissertation analyzes the change of climate along the railway and then develops a research on the effect of the changing geothermal temperature on permafrost table and its countermeasures.
