摘要

Evaluation of the impacts of prevailing climate change on rivers and water resources is significantly important in order to successfully manage water resources, particularly in snow-fed and glacier-fed catchments. The basic aim of this research was to assess the impacts of climatic variability on Astore and Hunza river-flows by employing long-term in-situ hydro-meteorological data. Times-series analysis of high- and low-altitude station data revealed consistent summer cooling, and warming in winter and spring seasons in both Karakoram and western Himalayan basins of Hunza and Astore, respectively. The intensity of these changes was not found to be identical in both basins, i.e. Hunza depicts slightly higher summer cooling rates and slightly lower annual, winter and spring warming rates as compared to Astore. Subsequently, the significant increase in annual precipitation of Hunza was also not found to be identical with Astore precipitation, which shows only a slight increase of precipitation. Notwithstanding, comparable temperature trends were observed at both high- and low-altitude stations; however, on the contrary, precipitation shows a different pattern of behavior, i.e. significantly increased winter precipitation at high-altitude Astore stations was in contrast to the precipitation recorded by low-altitude stations. The study suggested that climate change is significantly influencing the characteristics and hydrological resources of this region.

Hunza描绘了与Asors相比略高的夏季冷却率和稍微低下的年度，冬季和春季变暖率。随后，Hunza的年降水量显着增加也没有发现与Asore降水相同，这仅略微增加降水。尽管如此，在高空和低空站都观察到了相当的温度趋势;然而，相反，沉淀显示出不同的行为模式，即高空Astorations的冬季降水显着增加与低空站记录的降水相反。该研究表明，气候变化显着影响了该地区的特点和水文资源。
