The pressure placed on global water resources by landscape modification and various forms of pollution is being exacerbated by climate change. While substantial progress has been observed in the field of wastewater treatment, less attention has been given on how to reduce the impact of diffuse sources such as runoff from agriculture and urban areas. To make further progress in water quality management, stronger links with nature have to be made, through the implementation of new, ecosystem-based strategies to mitigate the impact of anthropopressure and build ecosystem resilience. A framework for the implementation of such solutions is provided by Ecohydrology, a science that translates abiotic-biotic processes ranging from the molecular to the catchment scale to develop new systemic management of water resources. An integral part of this strategy is the implementation of Ecohydrological Nature-based Solutions (EH-NbS) for water quality and quantity improvement. With growing popularity of such solutions questions arise about their future optimization scenarios. This short article presents (i) the current state of research and development in EH-NbS, (ii) recent hybrid advancements for enhancing NbS efficiency, and (iii) discusses the integration of EH-NbS with Circular Economy (CE) to facilitate broad-scale implementation.

气候变化加剧了景观改造和各种形式的污染对全球水资源造成的压力。虽然在废水处理领域取得了实质性进展，但对如何减少农业和城市径流等扩散源的影响却很少关注。为了在水质管理方面取得进一步进展，必须通过实施基于生态系统的新战略来减轻人类压力的影响并建立生态系统恢复力，从而加强与自然的联系。实施此类解决方案的框架由生态水文学提供，这是一门将非生物-生物过程从分子到集水区规模的科学，以开发新的水资源系统管理。该战略的一个组成部分是实施基于生态水文自然的解决方案 (EH-NbS)，以改善水质和水量。随着此类解决方案的日益普及，出现了有关其未来优化方案的问题。这篇简短的文章介绍了 (i) EH-NbS 的研究和开发现状，(ii) 提高 NbS 效率的最新混合进展，以及 (iii) 讨论了 EH-NbS 与循环经济 (CE) 的整合，以促进广泛-规模实施。
