冰川的退缩改变了冰冻圈地区的水文过程,并影响了流域规模的水资源。有必要阐明环境变化对冰冻圈主导地区蒸散量(ET)变化的贡献。考虑到疏勒河流域上游是典型的冰冻圈主导流域,构建了针对冰川变化的扩展Budyko框架,并应用该框架来研究环境变量变化对蒸散变化的敏感性和贡献。 1982—2015年研究区年蒸散量呈显着上升趋势,为1.158 mm yr−1。 ET 对降水量(P)最敏感,其次是控制参数(w),它反映了景观变化、潜在蒸散量(ET0)和冰川变化(ΔW)的综合影响。 P的增加是影响ET增加的主导因素,贡献率为112.64%,而w的减少很大程度上抵消了其影响。当使用扩展 Budyko 框架考虑冰川时,P 和 ET0 对 ET 变化的贡献减少,而 w 的贡献增加。冰川的变化对ET变化和水文过程起着明显的作用,这在冰冻圈流域中是不可忽视的。这些发现有助于更好地了解冰冻圈地区水资源的变化。
The retreat of glaciers has altered hydrological processes in cryospheric regions and affects water resources at the basin scale. It is necessary to elucidate the contributions of environmental changes to evapotranspiration (ET) variation in cryospheric-dominated regions. Considering the upper reach of the Shule River Basin as a typical cryospheric-dominated watershed, an extended Budyko framework addressing glacier change was constructed and applied to investigate the sensitivity and contribution of changes in environmental variables to ET variation. The annual ET showed a significant upward trend of 1.158 mm yr−1 during 1982–2015 in the study area. ET was found to be the most sensitive to precipitation (P), followed by the controlling parameter (w), which reflects the integrated effects of landscape alterations, potential evapotranspiration (ET0), and glacier change (∆W). The increase in P was the dominant factor influencing the increase in ET, with a contribution of 112.64%, while the decrease in w largely offset its effect. The contributions of P and ET0 to ET change decreased, whereas that of w increased when considering glaciers using the extended Budyko framework. The change in glaciers played a clear role in ET change and hydrological processes, which cannot be ignored in cryospheric watersheds. These findings are helpful for better understanding changes in water resources in cryospheric regions.
