| 英文简介 | Glacial runoff is vital supplies for the water use of production and life in the western arid and semi-arid regions of China, and under the global warming background, the physical process simulation of glacial ablation become the difficult and hot issues of Glaciology. Surface energy balance of the glacier is one of important methods for glacial ablation research, and the uncertainty of turbulent parameters restricts the credibility of the model. In the typical continental glacier of the Qilian Mountains (the Laohugou Glacier No.12), the observation of weather station and eddy-covariance system are carried out, and surface energy model is improved and the accurate simulation of glacial ablation is finished. The main researches are as follows: 1) The turbulent fluxes calculated by bulk aerodynamic method will be corrected by those observed from eddy-covariance system, and accurate surface roughness and bulk transfer coefficient are obtained. 2) Based on the turbulent parameters, surface energy balance model will be improved and the process of glacial ablation is simulated, which results will be validated by the measured deduced from the sonic ranging sensors and the stakes data. 3) Based on the glacial ablation simulation, the force influences of glacial ablation by dust will be quantified through the observed change of albedo. 4) Climate sensitivity test will discuss how the continental glacier responds to climate change under different settings. Based on the above research, the processes of glacial ablation will be understood from a physical mechanism, to lay the foundation for the quantitative evaluation of the changes of glacial runoff and the changes of glacier water resources in the Qilian Mountains. |
