在山地湖泊中,水的透明度主要由周围集水区装载的物质来调节。因此,由于影响水文输入的气象条件,湖泊内的透明度可能随时间而变化。此外,湖泊对这些输入的响应可能取决于流域特征。我们在加拿大不列颠哥伦比亚省的Yoho国家公园研究了13年来气象条件与透明度年际变化之间的关系。我们测量了320 nm的仲夏透明度衰减系数,并在研究湖泊附近的自动气象站每天收集气象数据。尽管它们距离很近,但在一定时间范围内,湖泊在透明度和累积降水之间的关联强度各不相同。具体而言,非冰川补给的Hungabee湖的透明度与采样前15天的累积降水相关性最强,而冰川补给的Opabin湖和Oesa湖受较长时间累积降水的影响最强烈。因此,湖泊透明度年际变化的时间同步性相对较小。我们的研究结果表明,在预测气候变化对山区湖泊生态系统的影响时,即使在单一区域内,也必须考虑降水的时间和数量以及当地的水文。
In mountain lakes, water transparency is regulated primarily by materials loaded from the surrounding catchment. Consequently, transparency within a lake can vary over time due to meteorological conditions that affect hydrologic inputs. Furthermore, lake responses to these inputs may depend on catchment characteristics. We examined the relationships between meteorological conditions and interannual variation in transparency over thirteen years in a set of four lakes in Yoho National Park, British Columbia, Canada. We measured mid-summer transparency as the attenuation coefficient of 320 nm and collected meteorological data daily with an automatic weather station located near the study lakes. Despite their close proximity, lakes varied in the strength of associations between transparency and cumulative precipitation across a range of durations. Specifically, transparency in non-glacially fed Lake Hungabee was most strongly correlated with cumulative precipitation in the fifteen days preceding sampling, whereas glacially fed Lakes Opabin and Oesa were most strongly affected by longer periods of cumulative precipitation. Consequently, there was relatively little temporal synchrony in interannual transparency variation among lakes. Our results suggest that both the timing and amount of precipitation as well local hydrology must be considered when predicting effects of climate change on mountain lake ecosystems even within a single region.
