It is widely accepted that the global warming will impact on water resources. This study investigates the possible influence of climate change on the water resources in an alpine region. A description of the actual situation with emphasis on the water resources from the one side and on the water consuming factors, here called stressors, is given. The probable effects of climate change in the region and their influence on its water resources are then described. The main outcome is that in the analysed region the climate change will rather have positive influence on the water balance by inducing higher precipitations during the rivers' natural low flow period (winter). This outcome contradicts many common predictions, however, this due to the specifics induced by the alpine nature of the catchment.
全球变暖将对水资源产生影响,这一点已得到广泛认可。本研究调查了气候变化对一个高山地区水资源可能产生的影响。文中一方面描述了该地区的实际情况,重点是水资源,另一方面描述了用水因素,这里称为压力源。接着阐述了该地区气候变化可能产生的影响及其对水资源的作用。主要结果是,在分析的地区,气候变化将通过在河流自然枯水期(冬季)带来更多降水,从而对水平衡产生积极影响。然而,这一结果与许多常见预测相悖,不过这是由集水区的高山特性所导致的特殊性造成的。
