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.

“共抓大保护、不搞大开发”是推动长江经济带高质量发展的战略导向,长江大保护要抓主要问题、采取针对性的措施策略。本文系统分析了长江经济带面临的主要水安全与水生态保护修复问题:防洪安全形势依然严峻、水生动物适宜生境萎缩严重且多样性降低、长江与通江湖泊关系失调。研究提出了针对性的水安全保障措施与水生态修复策略:一是加快重要蓄滞洪区的安全工程建设,修订《长江流域防洪规划》,提高防洪保安能力;二是在长江上游支流替代生境建设,在长江中下游实施部分原通江湖泊的恢复连通并扩大水库生态调度范围,修复受损生态系统;三是实施洞庭湖北部四口水系综合整治,在鄱阳湖出口建闸并进行调控,科学改善江湖关系。

近年来,华北地区实施了一系列生态保护与恢复工程,植被生态状况发生了显著变化;探究区域植被恢复对水循环过程及水资源供需平衡的影响,对于完善生态恢复策略、实现区域水资源可持续利用十分重要。本文采用皮尔逊相关系数和莫兰指数,结合多源水参量数据进行综合性分析,阐释了植被和不同水参量的时空变化情况,甄别了植被保育与恢复下的水资源变化响应,进而探讨了华北地区水资源与植被恢复的权衡关系。研究结果表明,华北地区的生态保护与恢复工程成效显著,植被净初级生产力的增速约为恢复工程区外的2.3 倍;植被的扩张与蒸散量表现出空间与时间上的强相关性;植被恢复引起的蒸散量提高是引起水储量赤字或显著降低的主要原因。为此建议,华北地区可完善生态恢复策略,在植被保育与恢复过程中考虑水资源的限制作用;以自然恢复方式为主,促进生态恢复的可持续性、水资源的可利用性。
