Abstract:

In order to solve the complex problems we face in ecosystem management in China, 25 pilot projects for ecosystem protection and restoration were implemented from 2016 to 2018 with positive outcomes. However, problems still exist, such as lacking a good understanding of the internal controls of ecosystems, overly relying on engineering approach and inadequate management policies. As one of the most accepted measures addressing societal challenges, Nature-based Solutions (NbS) have developed rapidly, with emerging concepts, principles and practices. This paper systematically sorts out the concepts, core theories and typical cases of NbS, and interprets, from the perspective of NbS, the problems in the pilot projects in terms of their spatio-temporal scale, goal setting, technical measures, and implementation and management strategies. We propose using NbS as reference to improve the ecosystem protection and restoration projects in China, which entails adopting a multi-scale, multi-objective design, setting multi-objective goals, and establishing a scientific technical framework and standard. Meanwhile, we aim to promote multi-party participation, economic sustainability, adaptive management and so on.

Key words: ecosystems, Nature-based Solutions, ecological conservation, ecological restoration
