This article provides a perspective on nature-based solutions. First, the argument is developed that nature-based solutions integrate social and ecological systems. Then, theoretical considerations relating to relational values, multifunctionality, transdisciplinarity, and polycentric governance are briefly outlined. Finally, a conceptual model of the social–ecological system of nature-based solutions is synthesised and presented. This conceptual model comprehensively defines the social and ecological external and internal systems that make up nature-based solutions, and identifies theoretical considerations that need to be addressed at different stages of their planning and implementation The model bridges the normative gaps of existing nature-based solution frameworks and could be used for consistent, comprehensive, and transferable comparisons internationally. The theoretical considerations addressed in this article inform practitioners, policymakers, and researchers about the essential components of nature-based solutions. The conceptual model can facilitate the identification of social and ecological interconnections within nature-based solutions and the range of stakeholders and disciplines involved. 相似文献

Due to freshwater supplement scarcity and heavy human activities, the fresh water wetland ecosystem in Yellow River Delta
is facing disintegrated deterioration, and it is seriously affecting the health of the Yellow River ecosystem. This paper
identifies the restoration objectives of wetland aiming to protect ecological and economic values and development as well
as the water resources of the Yellow River. The hydraulic and groundwater coupling model and Landscape Ecological Decision
and Evaluation Support System (LEDESS) of the Yellow River Delta were established to calculate environmental flows of degraded
wetlands. LEDESS is a computer-based model developed and used to assess and evaluate the effects of land-use changes on nature.
In this study, LEDESS is used to assess and evaluate the ecological effects and the restoration possibilities considering
several environmental flows’ supplement scenarios. This included the changes of suitable habitat conditions and its ecological
carrying capacities for indicator species, e.g., Red-crowned crane (Grus japonensis), Oriental stork (Ciconia boyciana), and Saunder’s gull (Larus relictus), and changing of ecological patterns. The results showed that replenishing fresh water to wetlands is one of the effective
adaptive measures to mitigate wetland degradation and improve its habitat quality and carrying capacities. This study indicated
that landscape ecology approach is not only considered as a good way to solve complex problems in ecosystem management but
also can be used to decide on the environmental flows and assess its ecological effects in large-scale wetland rehabilitation.
This integrated method could make environmental flows estimated and assessment more rational than the results of hydrologic
methods. It could assist decision makers to “see” the ecological effects after water supplementing and so alleviate the contradictions
between environmental flows and production water demands, and can facilitate the implementation of environmental flows in
most countries with water resources shortage. 相似文献
