| 摘 要： | 度日因子.冰崖坡向的变化也对度日因子产生了影响,总体表现为NEE-SE方向及SW-W方向的度日因子较大,NWW-N-NE方向的较小,S方向的最小,这主要与该地区的辐射、气温等气象条件的变化特征有关.研究还表明,冰崖的坡度对度日因子的影响较小.

| Abstract: | An ice cliff ablation experiment was conducted in the debris-covered area of the Koxkar Glacier during July 9-August 30,2007.In this experiment,some ablation stakes were set up on the bare ice surface of selected ice cliffs which were distributed at various elevations and had different orientation and slope.Together with the air temperature data recorded by the neighboring Auto Weather Stations,33 sets of valid ice ablation data had been used to calculate the positive degree-day factors.Data analyses show t... |
