“…At the national level, the concept of "mountains-rivers-forests-farmlands-lakes-grasslands life community" is a concept for ecological restoration. This concept is rooted in ecological ethics, environmental protection, and sustainable development theories, and aims to illustrate the interdependence and interaction among ecosystem elements, with the characteristics of wholeness, systematicness, and balance [23,24]. It reflects the synergy and organic connections among various ecosystems [25], and promotes the development of ecological restoration towards integration.…”

The Loess Plateau is the world’s largest loess landform region, characterized by a fragile ecosystem and frequent natural disasters that render it highly susceptible to ecological damage, highlighting urgent ecological restoration. We constructed a “Pattern-Service-Stress Ecosystem Quality Assessment Model” based on the connotation of ecosystem quality and the ArcGIS platform, then applied it to Suide County, a representative area of the Loess Plateau, as the research object. Next, using the dispersal ecology theory and the MCR model, we constructed an ideal ecological network. According to the quality assessment and ecological network analysis, we selected areas with low ecosystem quality within the scope of an ecological corridor as key areas for restoration. Finally, we proposed restoration strategies using regional ecological techniques. This study yielded the following results: The spatial pattern of ecosystem quality in Suide County exhibited a “high in the south and low in the north” pattern, with a high-value area of 823.87 km2, and a low-value area of 509.31 km2, accounting for 44.45% and 27.48% of the total area, respectively. In Suide County’s ecological network, the spatial distribution of ecological sources and corridors is dense in the south and sparse in the north, with a significant amount of path overlap within ecological corridors. Located on the southern ecological corridor of Suide County, forty-five key areas for restoration were classified into seven types. Eight problems were identified in the key areas, and twenty-three targeted restoration measures were proposed. These measures can result in 6.44 km2 of forest land and 5.26 km2 of grassland, improving the ecosystem quality of the key areas and even the entirety of Suide County. This study guides Suide County’s ecological restoration work and provides a paradigm for ecosystem quality assessment and ecological restoration on the Loess Plateau, pointing out directions. It has a certain radiation-driven effect and an important reference significance for ecological restoration in ecologically fragile areas.

Important for promoting the integrated protection and systematic management of mountains, rivers, forests, farmlands, lakes, grasslands, and sandy areas, ecological networks form the backbone of the regional ecological security pattern. An improved morphological spatial pattern analysis coupled with a minimum cumulative resistance model (MSPA–MCR) based on multi-source data was used to study, on a provincial scale, the ecological security pattern of Ningxia, an ecologically fragile region in the upper reaches of the Yellow River in China. The results show the following: (1) A reasonable classification of ecological sources and ecological corridors is key to constructing hierarchical ecological networks. Classifying ecological sources by replacing patch areas with energy factors and identifying the importance of ecological corridors by modifying the gravity model with the energy factors proposed in this paper could improve the rationality of the hierarchical structure division of ecological networks. (2) Grassland as the substrate vegetation type is an important ecological source type in arid and semi-arid ecologically fragile areas, and forests and lake wetlands are the main ecological source types in mountainous areas and oasis areas, respectively. The study area was located in the arid–semi-arid transitional area, with a variety of ecological types, such as mountain, oasis, and desert. Therefore, the complex ecological source types of forest–grassland–wetland appear in some areas. (3) There are 45 ecological patch groups that can be classified as ecological sources in Ningxia, including 10 primary source groups. The number of primary source groups is small, and their spatial distribution is unbalanced. There are two categories of ecological corridors, the river corridor and the mountain corridor, and the network connectivity is poor. (4) The ecological network structure of Ningxia is presented as an ecological security structure consisting of one belt, three screens, three corridors, and five clusters, forming a hierarchical nested ecological network security structure system.

“…According to international practices, when ecological conservation and restoration projects have an impact on ecosystems, comprehensive and in-depth cost-benefit analyses of the project should be carried out as required by more and more management and financial parties (Peng et al, 2019). The effectiveness and sustainability of ecological restoration needs to be considered not only for ecological benefits but also for socio-economic effectiveness.…”

The value realization pathways of ecological products are major challenges for China’s ecological civilization construction, which plays a critical strategic and practical role. In the process of ecological restoration projects, the selection of value realization pathways provides a feasible basis for the practice of ecological restoration. Cost-benefit analysis can be used to select the best restoration measures or models for the government or businesses, maximizing the environmental and economic benefits of restoration projects. This paper reviewed the value accounting research related to cost-benefit assessment in China. Currently, traditional independent empirical studies on specific ecosystem services are the focus of research and some policies have been established from these. In the assessment, the relevant methods were seen to still have limitations in terms of data sources, reference systems, and database improvement. It is noted that the benefit transfer method is still underdeveloped in China but has good prospects. The paper analyzed the main role of benefit transfer in policy making and the method’s scientific development, as well as elucidating the problems and challenges of the benefit transfer method. This study also presents a review of current policies and research on ecosystem service valuation policies and potential ways for ecological restoration. Due to the great spatial variations in socio-economic conditions and resource endowments in different regions in China, it is necessary to consider regional differences and adjust ecological restoration to local conditions. Furthermore, relevant realization paths and future research perspectives were put forward.
