Paper Title:
Numerical Simulation of the Change of Gas Hydrate Layer of Qinghai-Tibet Plateau in Global Warming Situation
  Abstract

Using finite element method, we solve the heat conduction equation. In our calculation, we use 0.02 and 0.052 °C/year as temperature rising rate (Gt) in order to get the change of gas hydrate layer of Qinghai-Tibet Plateau (QTP) in global warming situation. Our calculation’s major results are as follows: Our calculation demonstrates the gas hydrate layer’s surface temperature is one of the major factors which influence the thickness of gas hydrate layer (TGH). When Gt=0.02 and 0.052°C/year, the changes of TGH are almost same. The lower the ground surface temperature (GST), the more change of TGH. Therefore we need to monitor the Qiangtang plateau which has low surface temperature and good organic material.
