摘要
The lakes on the Tibetan Plateau(TP)account for 57%of the total lake area in China[1],which is a key component of the Asia water tower[2-4].A recent study showed that there are 1424 lakes greater than 1 km^(2) on the TP,while the total lake area reached 5.0-10^(4)±791.4 km^(2) in 2018[5].Most lakes on the TP are closed and are less disturbed by human activities than the other inland water bodies in China.
青藏高原广泛分布的湖泊是"亚洲水塔"的重要组成部分.对该地区湖泊水质的调查与研究,是区域水环境与水资源评估以及气候和环境变化研究的重要基础. 20世纪80年代之前的第一次青藏高原综合科学考察之后,对该地区大范围湖泊水质调查十分匮乏.本研究基于2009~2020年期间野外调查工作,共采集获取涉及124个封闭湖泊的实测水质参数.调查与研究表明,青藏高原湖泊盐度变化很大,大多数湖泊表现出碱性状态,富营养化程度低,叶绿素a和溶解有机物浓度低、浊度低、透明度高.分析显示部分湖泊水质参数随空间、季节、面积变化而发生较大变化.本研究揭示了青藏高原湖泊水质近期基本状态与规律,为区域生态、水文、资源、环境与气候变化等研究提供了基础数据.
