Abstract:

Wetland is an important natural resource for human beings and plays an irreplaceable ecological function in the terrestrial ecosystem. In order to curb the continued loss of wetlands around the world, international organizations and many countries have taken a series of major protection and restoration measures. This paper reviews the wetland protection and restoration measures of international organizations and some countries, comprehensively interprets China's wetland protection and restoration management experience, and proposes that future research on wetland resources should be carried out from the aspects of international frontier and national strategy, social economy and intelligent services. The results show that: (1) The 27 International Wetlands Day from 1997 to 2023 provide new goals and tasks for the protection and management of wetlands in corresponding years. The important topics and outcomes of the 14 International Convention on Wetlands Conferences from 1980 to 2022 provide new directions and new challenges for wetland development in the coming period. In the future, we should enhance ecological functions of wetlands, promote the sustainable development of wetlands, and overcome the technical bottleneck of ecological restoration of fragile wetland ecosystems from 2020 to 2035. (2) During the 30-year period from 1992 to 2022, China embarked on a new phase of wetland protection and restoration. The overall experience of wetland protection and restoration with Chinese characteristics has been formed through "national strategic deployment-legal policy establishment-project planning and implementation". Emphasis was placed on the need to provide for and prepare planning for the long-term protection of wetlands at the national legal level, to innovate restoration and management techniques and application systems, and to effectively address the complex issues of wetland protection and restoration through collaborative division of labor among multiple departments. (3) The research on the future trend of wetlands should be directed towards the exploration and practice of "United Nations Sustainable Development Goals and several international conventions" in support of the sustainable development of wetlands. Wetland protection, restoration and management services should be promoted for "national strategic needs and local social and economic high-quality development". Research on the cross-integration and academic innovation development also should be enhanced for "disciplinary development - global supervision - comprehensive assessment-intelligent decision-making".
