Elucidating the spatiotemporal pattern of water quality and algal biomass is crucial for accurately tracing pollution sources and reducing the risk of algal blooms in lake systems. This study analyzed the spatiotemporal variability of water quality and algal biomass in Erhai Lake from 1994 to 2021 using water quality index (WQI), Mann-Kendall test and Sen’s slope combined methods. The potential causes of water quality deterioration and algal biomass dynamics were also elucidated. The results showed that the historical changes in the water environment of Erhai Lake mainly had three stages: satisfactory (1994‒2001), deteriorating (2002‒2010) and improving (2011‒2021). The changes in water quality and algal biomass were primarily affected by total nitrogen, total phosphorus and chemical oxygen demand in different stages. The water environment of Erhai Lake is currently improving significantly, starting in the southern area that is furthest from the sources of agricultural pollution, especially in summer and autumn. This is attributed to the implementation of control measures resulting in lower pollutant loads at particular times and places. Therefore, it is necessary to continue to promote standardized livestock farming, to strengthen rural wastewater collection and to investigate measures such as the interruption of the endogenous cycle.

认识云贵高原的环境变化在局地、区域和全球三个层面上具有重要意义。不同湖泊沉积物—水界面的生物地球化学过程具有重要差别,因而其水源保护途径也不尽相同。a. 贵州阿哈湖汇水区煤矿开采导致Fe—Mn在沉积物中积累并产生季节性二次污染。缺氧季节硫酸盐还原作用上移至沉积物顶部,导致界面亚扩散层对Fe2+的屏蔽,Fe—Mn循环受沉积物—水地质界面和氧化—还原化学界面的双重控制。控制Fe—Mn释放和降低入湖通量、选取优质水区和清淤处理是污染控制的有效途径。b.1994年秋贵州百花湖出现“突发性”水质恶化,剖析相互关联水质指标表明:“湖泊黑潮”是特定季节、特殊气候条件下,沉积有机质生物氧化作用的耦合;脱氮过程受阻的pH控制导致亚硝酸根浓度增高。随着水体耗氧—复氧平衡、水流输送及天气好转,水质可望在一段时期内复苏。后期观测表明了水质的好转。c.云南洱海沉积物平均堆积速率为0.047 g ·cm-2 ·a-1;沉积物顶部几厘米Pb稳定同位素组成表明其铅来源稳定;沉积有机质主要为陆源,早期成岩过程Corg垂直剖面具“沉降—降解—堆积”三阶段分布。近460年间,δ13Corg小幅度频繁波动及δ13Cinorg和δ18Oinorg同步降低的总趋势表明汇水区人为活动的明显影响。控制陆源有机质的输入通量是保护洱海的基本策略。d.云南程海是一个湖水离子总浓度接近盐湖下限的中度富营养湖泊。沉积物Horg/Corg和Corg/Norg原子比率表明其有机质主要源于内生浮游藻类残骸;沉积记录中210Pbex与Corg的沉积通量显示出良好的同步关系。特别是二者同步增大时段表明:210Pbex沉积通量增加指示湖泊初级生产力增大,这种微粒清洗效应反映了湖泊自然作用对富营养演化的调控作用。

Interbasin water-transfer schemes provide an engineering solution for reconciling the conflict between water demand and availability. In the context of climate change, which brings great uncertainties to water resource distribution, interbasin water transfer plays an increasingly important role in the global water–food–energy nexus. However, the transfer of water resources simultaneously changes the hydrological regime and the characteristics of local water bodies, affecting biotic communities accordingly. Compared with high economic and technical inputs water-transfer projects require, the environmental and ecological implications of water-transfer schemes have been inadequately addressed. This work selects the largest water-transfer project in China, the South-to-North Water Diversion (SNWD) Project, to critically review its eco-environmental impacts on donor and recipient basins, as well as on regions along the diversion route. The two operated routes of the SNWD Project represent two typical water diversion approaches: The Middle Route uses an excavated canal, while the East Route connects existent river channels. An overview of the eco-environmental implications of these two routes is valuable for the design and optimization of future water-transfer megaprojects.
