| 英文摘要 | Based on the field observations on Qiyi Glacier during the warm season of 2007, using a digital elevation model (DEM, 15 m resolution), we developed a distributed surface energy- and mass-balance model with an hourly resolution. The model described the effect of topography on shortwave solar radiation, and used a new parameterization for glacier albedo. The model was applied to Qiyi Glacier in the Qilian Mountain, China, for the period 20: 00 30 June to 12: 00 10 October 2007, to simulate the firn-line changes, the temporal and spatial variations of mass balance, and the glacial meltwater runoff. The results indicated that the patterns of altitudinal profile of glacier mass-balance were affected mainly by the altitudinal profile of albedo, and the status of the glacier mass balance was influenced directly by the values of albedo. The parameter sensitivity test showed that the model was sensitive to the air temperature lapse rate and precipitation gradient, and also sensitive to the threshold temperature for solid/liquid precipitation. Furthermore, the climate sensitivity test showed that the mass balance was more sensitive to air temperature than precipitation, and the response of mass balance to air temperature change was nonlinear while the response to precipitation change linearly. The negative mass balance trend of the glacier can not be reversed when precipitation increases by 20% and meanwhile air temperature rises by 1A degrees C. |
