Thoughts and Practice of Ecological Protection and Restoration of Mountains, Rivers, Forests, Farmlands, Lakes and Grasslands

The report of the 19th National Congress of the Communist Party of China stated that it was necessary to establish and practice the concept that lucid waters and lush mountains are invaluable assets,treat the ecological environment as life,and coordinate the management of mountains,rivers,forests,farmlands,lakes and grasslands.In recent years,China has organized a series of pilot projects for the ecological protection and restoration of mountains,rivers,forests,farmlands,lakes and grasslands,breaking the boundary between administrative divisions,departmental management and ecological elements,and implementing conservation and restoration oriented towards the improvement of ecosystem services,so as to solve the problem of the lack of overall planning for ecological protection and restoration projects and the separated management of ecological elements.This study systematically elaborated the theoretical basis and connotation characteristics of ecological protection and restoration of mountains,rivers,forests,farmlands,lakes and grasslands.It proposed the implementation path of ecological protection and restoration project of mountains,rivers,forests,farmlands,lakes and grasslands by taking the water source conservation area of Beijing-Tianjin-Hebei as a case,so as to provide reference for the implementation and decision-making management of ecological protection and restoration projects in various regions.

Current Situation and Ideas of Protection and Restoration of Aquatic Ecosystems in Rivers and Lakes of China

Based on the investigation and analysis of protection and restoration of aquatic ecosystems in rivers and lakes of China, the ideas and measures of restoring aquatic ecosystems were proposed to build healthy aquatic ecosystems of rivers and lakes in China, such as setting scientific and clear goals, improving the standard adopted by wastewater treatment plants, controlling sources of pollutants and intercepting pollutants, collec- tion of blue-green algae, water transfer, dredging, reducing the quantity of blue-green algae, restoring reed wetlands on a large scale, combing dredging and base raise of restored reed wetlands, making full use of microorganisms, and implementing effective management, technology integra- tion and innovation.

Research on Ecological Protection and Restoration Measures in Altay Region based on the Coupling Perspective of the Mountains-Rivers-Forests-Farmlands-Lakes-Grasslands System

The adoption of both Nature-based Solutions(NbS)and a system perspective is a hot issue and an area in which there is much room for improvement in ecological protection and restoration.The study takes Altay region as an example,an area located in Xinjiang,China,which is an important ecological corridor of the national key functional area and the core area of the Belt and Road but has a fragile ecological environment and needs much enhancement in ecological protection and restoration.Guided by the concept of"mountains-rivers-forestsfarmlands-lakes-grasslands(MRFFLG)system is a life community",the coupling relationship of the various MRFFLG elements,the main ecological environmental problems and the integrated countermeasures for protection and restoration in Altay region have been analyzed in this study.The study shows that Altay region has a typical meta-ecosystem of mountain,oasis,and desert,and the connections by rivers and lakes make the ecosystem links within the region much closer.The interweaving of resource-environmental-ecological issues of the aquatic ecosystem,degradation of the quality of terrestrial ecosystems such as forests,grasslands and farmlands,the increased ecosystem fragmentation and ecological risks are the major ecological environmental issues in this region.This study takes the improvement of the ecosystem health and function in Altay region as the core goal of regional ecological protection and restoration.First,we establish a zoning governance pattern from the perspective of ecosystem integrity;second,we design governance strategies for different zones with the goal of synergistic improvements in the ecosystem functions;and finally,we clarify the key engineering tasks in different zones from the perspective of ecosystem services.Ecological conservation and restoration of the MRFFLG system is a prime example of the application and development of NbS in China.This paper constructs an analytical framework for identifying regional life communities,diagnosing ecological protection and restoration of zoning problems,and proposing classified solutions for ecological protection tasks for the protection of the MRFFLG system.This research will enrich the theory and technology for the protection and restoration of MRFFLG systems,and provide guidance for the practice of ecological protection and restoration in Altay region.

Heritage and Development of Ningbo Bone-Inlaid Wooden Works

Bone-inlaid wooden art is a very old artistic form that has a strong artistic appeal and local flavor. It can be traced back to the Longshan Culture in the late Neolithic Age, and becomes mature in the late Qing Dynasty. As time lapses, however, bone-inlaid wooden art is gradually out of sight. It was not until June 2008 when Ningbo bone-inlaid wooden art was included in the "second batch of national intangible cultural heritage protection list" that it once again caused social concern. Ningbo bone-inlaid wooden art has a long history, and its craftsmanship is complex. Many bone-inlaid wooden works in Ningbo have been damaged more or less. Therefore, workers in the field of heritage protection should undertake a more systematic protection and repair work based on scientific research, making contributions to the heritage and development of intangible cultural heritage.

中国湿地保护修复管理经验与未来研究趋势

Wetlands are important natural resources for humans and play an irreplaceable ecological function in the terrestrial ecosystem.To curb the continued loss of wetlands globally,international organizations and many countries have taken a series of major conservation and restoration measures.This work reviews these wetland conservation and restoration measures,interprets China’s wetland conservation and restoration management policies,and proposes that future research on wetland resources in China should be conducted from the aspects of international frontiers and national strategic plans,socioeconomics,and smart services.The results show that the 27 International Wetlands Days from 1997 to 2023 provided new goals and tasks for the protection and management of wetlands.The important topics and outcomes of the 14 Conferences of the Contracting Parties to the Convention on Wetlands from 1980 to 2022 provided new directions and new challenges for wetland development.In the future,we should enhance wetland ecological functions,promote sustainable wetland development,and overcome the technical bottleneck of fragile wetland ecosystem restoration.From 1992 to 2022,China embarked on a new phase of wetland protection and restoration.The overall experience of wetland protection and restoration in China has been formed through national strategic deployment,legal policy establishment,and project planning and implementation.The needs to provide for and plan the long-term protection of wetlands at the national 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 were emphasized.Research on the future trends of wetlands should be directed towards the exploration and practice of the United Nations Sustainable Development Goals and several international conventions in support of sustainable wetland development.Wetland protection,restoration,and management services should be promoted for national strategic needs and local,high-quality social and economic development.In addition,research on cross-integration and academic innovation should be enhanced for disciplinary development,global supervision,comprehensive assessment,and smart decision making.
