摘要

在联合国生态系统恢复十年(2021-2030)框架内,一种基于自然的解决方案(NbS)进行了试验,利用诺氏短尾藻移植来恢复历史上受污染的潮间带区。原位移植依靠来自供体草甸的海草和沉积物斑块,其演变监测了两年。移植成功的评价指标包括海草覆盖面积、海草生物量、组织汞积累和光合效率。移植是成功的,目标地区的覆盖面积在第一年之后逐渐增加,表明已经适应了当地的条件。虽然在生物量和组织汞浓度随时间的变化中观察到一些显著的差异,但相似的转运因素表明植物具有有效的防御机制来防止积累和细胞损伤。此外,正常的光合参数季节性模式表明污染不会妨碍其光合性能和生长,表明NbS是一种可行的恢复策略。

Transplantation of seagrass (Zostera noltei) as a potential nature-based solution for the restoration of historically contaminated mudflats.

Within the UN Decade on Ecosystem Restoration (2021-2030) framework, a Nature-based Solution (NbS) using Zostera noltei transplants was tested to restore a historically contaminated intertidal area. In-situ transplantation relied on patches of seagrass and sediment from a Donor meadow and its evolution was monitored for two years. The evaluation of the transplant success encompassed the seagrass coverage area, seagrass biomass, tissue mercury (Hg) accumulation, and photosynthetic efficiency. The transplant was successful, with gradual increases in the coverage area in the target area indicating adaptation to local conditions already after the first year. Although some significant differences were observed in biomass and tissue Hg concentration over time, the similar translocation factors suggest the plant has effective defensive mechanisms to prevent accumulation and cellular damage. Additionally, the normal seasonal pattern of photosynthetic parameters indicates that contamination is not impeding its photosynthetic performance and growth, suggesting this NbS as a viable restoration strategy.

期刊介绍: The Science of the Total Environment is an international journal dedicated to scientific research on the environment and its interaction with humanity. It covers a wide range of disciplines and seeks to publish innovative, hypothesis-driven, and impactful research that explores the entire environment, including the atmosphere, lithosphere, hydrosphere, biosphere, and anthroposphere. The journal's updated Aims & Scope emphasizes the importance of interdisciplinary environmental research with broad impact. Priority is given to studies that advance fundamental understanding and explore the interconnectedness of multiple environmental spheres. Field studies are preferred, while laboratory experiments must demonstrate significant methodological advancements or mechanistic insights with direct relevance to the environment.
