Lingbao city is located in the middle reaches of the Yellow River and the eastern part of the Xiaoqinling Mountains, which is of great significance as an ecological safety barrier. This paper takes Lingbao city as an example to carry out the research on ecological protection and restoration of mountains, rivers, fields, lakes and grasses. On the basis of understanding the current situation of the ecological environment in Lingbao city, the principle of "Overall protection, systematic restoration and comprehensive management" was established, and the spatial layout of "One mountain, one tableland and one river" ecological protection and restoration was proposed. Five ecological engineering categories, namely, mountain ecological environment protection and restoration, water ecological environment protection and restoration, forest ecological environment protection and restoration, land improvement and yellow river ecological environment protection and restoration, were deployed to assist the high-quality development of the yellow river basin. The mechanism and measures to promote the ecological protection and restoration project are discussed. The research results can provide support for the local government to practice the "Two Mountains Theory".展开更多

文摘The issue of marine ecology is an institutional one.China’s marine ecological protection system has gone through a process of development from scratch to existence and from less to more.However,there are still many problems to be solved,such as whether a variety of complex systems can form a joint force of governance,and whether the rear system failures,deficiencies,and conflicts.Therefore,this paper reviews the evolution logic of China’s marine ecological protection system,explores the complementary space of the existing system from the perspective of institutional complementarity,and analyzes the path of institutional reform of supplement,amendment,and coordination,to promote the effective transition of marine ecological protection system emphasizing quality over quantity.The evolution of China’s marine ecological protection system can be divided into three stages:initial establishment,steady progression,and gradual transformation,showing a trend characterized by a changing governance mode from land-sea division to land-sea integration,a changing supervision mode from government only to multi-institution coordination,a changing safeguard mode from standard norms to the legal system.The internal motivation of promoting the evolution of the marine ecological protection system is the link age between the long-overdue institutional derived demand and supply,and between institutional cost constraints and institutional income drivers.Marine ecological protection is a complex and systematic project across regions and departments,and the link age between different ecological protection systems is crucial.Based on the theory of institutional complementarity,this study finds that China’s marine ecological protection system has great complementarity needs in three aspects:protection subject,protection means,and protection process.Among them,the problem of a single unitary protection subject is mainly caused by the lack of system,the low efficiency of protection means is mainly affected by the lack of system adaptability,and the separation of protection process mainly reflects the contradiction of system incongruity and mismatch.Based on this,the supplement of China’s marine ecological protection system should focus on the government’s responsibilities and the cultivation of multiple subjects.The revision of the system should focus on the further improvement of non-governmental mechanisms such as market incentives and information disclosure.The coordination of the system should be based on the whole process from pre regulation preparations to post-regulation review,in order to promote the effective connection and cooperation of policy tools.

文摘It is an important issue for sustainable economic development to give consideration to both project development and environmental protection.At present,we must confront and seriously deal with the problems of rational utilization of resources,protection of the environment and beautification of the environment in engineering construction.This paper describes a variety of slope plant protection technology,which can not only play a good role in slope protection,but also improve the engineering environment and reflect the beauty of natural environment,so as to provide reference for slope ecological protection.
文摘This paper firstly discusses the positive role of forestry ecological protection in the development of nature, human society and society. Secondly, it points out the lagging problems in the implementation of forestry ecological protection in China. Finally, it puts forward the innovative development ideas of forestry combined with the development needs of modern forestry and the requirements of ecological protection, which provides a reference for the development of forestry ecological protection.
文摘The report of the 19th National Congress of the Communist Party of China proposed that "we should coordinate the systematic management of mountains, rivers, forests, fields, lakes and grasses" The ecological protection and restoration project of the mountains, rivers, forests, fields, lakes and grasses is an important part of the construction of ecological civilization, and is also an inevitable requirement for the protection of biodiversity and the realization of carbon neutrality and peak carbon dioxide emissions. Lingbao city is located in the middle reaches of the Yellow River and the eastern part of the Xiaoqinling Mountains, which is of great significance as an ecological safety barrier. This paper takes Lingbao city as an example to carry out the research on ecological protection and restoration of mountains, rivers, fields, lakes and grasses. On the basis of understanding the current situation of the ecological environment in Lingbao city, the principle of "Overall protection, systematic restoration and comprehensive management" was established, and the spatial layout of "One mountain, one tableland and one river" ecological protection and restoration was proposed. Five ecological engineering categories, namely, mountain ecological environment protection and restoration, water ecological environment protection and restoration, forest ecological environment protection and restoration, land improvement and yellow river ecological environment protection and restoration, were deployed to assist the high-quality development of the yellow river basin. The mechanism and measures to promote the ecological protection and restoration project are discussed. The research results can provide support for the local government to practice the "Two Mountains Theory".

文摘Slope protection has always been a major concern in highway construction and later operation.Ecological protection technology is widely used in highway slope,which takes into account functions of protection,ecology,and landscape.Ecological protection technology is mainly to improve the stability of the slope through the combination of supporting structure and plants,and vegetation restoration can reduce the negative impact of highway construction.In this paper,the latest research progress of ecological protection technology was first reviewed to identify the main construction process and types,which revealed the protection mechanism of ecological protection technology.The comprehensive benefits of ecological slope protection technology were analysed from the aspects of air,water circulation,landscape and biodiversity.It has found that ecological protection technology of highway slope mainly forms the atmosphere-plant-soil system.Ecological protection technology of highway slope improved the stability of the slope through the supporting structure and the anchoring effect of plant roots.And the restoration of the surface vegetation on the slope promoted the photosynthesis and transpiration of plants and purifies the air quality along the highway.Ecological protection technology of highway slope could quickly restore the ecological balance,overall landscape and biodiversity of the region.

文摘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.
