摘要

水生生态系统的有效管理和恢复依赖于“参考条件”的建立,参考条件被定义为在没有人为影响的情况下的预期条件,并且需要对系统内的自然变异性有透彻的了解。然而,至少在欧洲,大多数系统的调查都是在人类对水生生态系统造成压力的开始之后进行的,因此未能捕捉到已经提前的水化学和动植物的早期退化。古湖泊学方法可用于评估人为压力源的范围,但系统内的可变性通常被平滑处理以给出长期模式。在这里,我们收集了来自各种来源的监测、文献和档案记录,以扩展我们对百年尺度湖泊生态系统变化和盐度增加的恢复的理解。我们以Thurne Broads浅湖滨海湿地系统(英国Broads国家公园)为例进行了研究,该系统受到了人为陆地排水和北海风暴潮(主要在1938年和1953年)的多重压力,这些压力已经影响了盐度。尽管仍有明显的数据缺口和与富营养化的相互作用尚不清楚,但我们证明,历史数据源可以结合使用来观察季节模式,并扩展对过去盐度变化和大型植物群落结构的了解,可以追溯到19世纪。在1938年CE的海水洪水之后,观察到生态系统发生了明显的变化,当时Thurne broad部分地区的盐度水平接近海水。随着20世纪后期人为压力的增加,该系统未能完全恢复。未来的管理,在平衡多个用户需求的同时,应关注当前盐度的季节性大波动以及系统对未来盐度大幅增加的脆弱性。

The role of monitoring, documentary and archival records for coastal shallow lake management
The effective management and restoration of aquatic ecosystems rely on the establishment of “reference conditions,” defined as the conditions expected in the absence of anthropogenic impacts, and require a thorough understanding of the natural variability within a system. However, at least in Europe, most systematic surveys post‐date the onset of human‐induced pressures on aquatic ecosystems, and thus fail to capture earlier degradation to water chemistry and flora and fauna, which were already advanced. Paleolimnological methods can be used to assess a range of anthropogenic stressors, but variability within a system is often smoothed to give long‐term patterns. Here, we compile monitoring, documentary, and archival records from a range of sources to extend our understanding of centennial‐ scale lake ecosystem change and recovery from increasing salinity. We use a case study of the Thurne Broads shallow lake coastal wetland system (Broads National Park, UK), which has been subjected to multiple pressures of anthropogenic land drainage and North Sea storm surges (primarily in 1938 and 1953 CE) that have influenced salinity. Although there are still periods with significant data gaps and the interactions with eutrophication remain unclear, we demonstrate that historical data sources can be used in combination to observe seasonal patterns and extend knowledge on past salinity change and macrophyte community structure back to the 1800s. A demonstrable change in the ecosystem is observed after the sea flood of 1938 CE, when salinity levels in parts of the Thurne Broads were close, or equivalent, to seawater. With the added anthropogenic pressures of the late 1900s, the system has failed to fully recover. Future management, whilst balancing the needs of multiple users, should focus on the current large seasonal fluctuations in salinity and the vulnerability of the system to future large salinity increases.

期刊介绍: Geo is a fully open access international journal publishing original articles from across the spectrum of geographical and environmental research. Geo welcomes submissions which make a significant contribution to one or more of the journal’s aims. These are to: • encompass the breadth of geographical, environmental and related research, based on original scholarship in the sciences, social sciences and humanities; • bring new understanding to and enhance communication between geographical research agendas, including human-environment interactions, global North-South relations and academic-policy exchange; • advance spatial research and address the importance of geographical enquiry to the understanding of, and action about, contemporary issues; • foster methodological development, including collaborative forms of knowledge production, interdisciplinary approaches and the innovative use of quantitative and/or qualitative data sets; • publish research articles, review papers, data and digital humanities papers, and commentaries which are of international significance.
