青藏铁路路基表面太阳总辐射和温度反演方法

通过对“青藏铁路乌丽垭口大桥段不同走向路基表面热状况观测试验”资料的分析，改进了已有的青藏铁路边坡表面上的太阳总辐射和表面温度反演方法，并利用中日合作“青藏高原能量水分循环试验”（GAME Tibet）沿青藏公路长时间序列地面观测资料，建立了地理位置和海拔高度与反演系数之间的统计关系，将该反演方法推广到青藏铁路全线。

Calculating Method of Global Radiation and Temperature on the Roadbed Surface of Qinghai-Xizang Railway

The calculating method of global radiation and surface temperature on the roadbed of the Qinghai-Xizang Railway is improved by analyzing the experiment data observed on roadbeds with different railway directions at Wuli. In order to apply this method to all roadbed of the Qinghai-Xizang Railway, a statistical correlaion of calculating parameters with roadbed location and elevation is set up. The long term date series of GAME-Tibet (GAME experiment of engine and water cycle in the Tibetan Plateau which was implemented under the cooperation project between two sides of China and Japan) obtained from the observation site along the Qinghai-Xizang Railway is involved to develop the method.
