In many dry parts of the world, salinization of water resources threatens freshwater biodiversity and the livelihood of people. However, ecological impact studies remain scarce. Here, we review field-observations of salinity impacts on ecosystem processes such as leaf decomposition, metabolism, biomass production and nutrient cycling, with a special emphasis on dryland ecosystems. In addition, we discuss the potential linkages of these processes to ecosystem service delivery-the benefits that humans derive from ecosystems-as additional nature conservation arguments and the challenges associated with this endeavour.This article is part of the theme issue 'Salt in freshwaters: causes, ecological consequences and future prospects'.
在世界上许多干燥地区,水资源的盐化威胁着淡水生物多样性和人们的生计。然而,生态影响研究仍然很少。在这里,我们回顾了盐分对生态系统过程的实地观测,如叶片分解、新陈代谢、生物量生产和养分循环,特别强调了旱地生态系统。此外,我们还讨论了这些过程与生态系统服务提供(人类从生态系统中获得的利益)的潜在联系,作为额外的自然保护论据,以及与这一努力相关的挑战。本文是主题为“淡水中的盐分:成因、生态后果和未来展望”的一部分。
