冰川融水作为山块补给来源的重要性仍然缺乏量化,但它可能通过维持溪流中的基流和泉中的常年流而对高山水生生态系统的完整性至关重要。我们使用传统的稳定同位素来源鉴定技术结合微生物DNA的新应用,验证了高山冰川融水是山地地下水系统补给的关键来源的假设。我们发现高山冰川融水不仅是许多泉水的重要水源,而且主要由冰川融水支持的高山泉水中含有与主要由季节性补给支持的泉水不同的微生物类群。因此,冰川融水的补给对于维持高山泉水的流动至关重要,并支持其独特的微生物群。
The importance of glacier meltwater as a source of mountain-block recharge remains poorly quantified, yet it may be essential to the integrity of alpine aquatic ecosystems by maintaining baseflow in streams and perennial flow in springs. We test the hypothesis that meltwater from alpine glaciers is a critical source of recharge for mountain groundwater systems using traditional stable isotopic source-identification techniques combined with a novel application of microbial DNA. We find that not only is alpine glacier meltwater a critical source of water for many springs, but that alpine springs primarily supported by glacial meltwater contain microbial taxa that are unique from springs primarily supported by seasonal recharge. Thus, recharge from glacial meltwater is vital in maintaining flow in alpine springs and it supports their distinct microbiomes.
