“…Scientifically delineating zones enhances the precision and targeting of ecological restoration, serving as an important prerequisite for spatial control of ecological restoration projects and differentiated spatial governance (Yue et al, 2022). Currently, ecological restoration primarily focuses on administrative units or natural watersheds, and zoning methods include research frameworks based on regional dominant functions (Tian et al, 2017;Cai et al, 2020), ecological security pattern construction (Ni et al, 2020;Jiang et al, 2022;Zhang et al, 2023), supply-demand of ecosystem services (Xie et al, 2020;Yue et al, 2022;Hu et al, 2023;Li et al, 2023c), comprehensive indicator systems. Regional context, landscape heterogeneity, human activities, socio-economic are interplay with ecosystem, which needs to be integrated during ecological restoration zoning, the comprehensive indicators not only offer an intuitive depiction of the ecological characteristics and interplay of human activities and economic growth but can also be aligned with the critical objectives of enhancing the level of ecosystem services.…”

Ecological restoration holds great significance in addressing environmental degradation and rock desertification in karst areas. Zoning strategy is a fundamental task in understanding the interrelationship between human-environment to foster sustainable development. We explore “social-ecological” system and conduct a case study on the karst region in Guangdong Province, China. An evaluation framework consists of “development pressure”, “sensitivity status”, and “resilience potential” was established. The results show that: regions with high pressure of development are predominantly located in high-density urban areas. The generally distribution of the comprehensive status index exhibits significant spatial heterogeneity. Regions with low sensitivity are found on the eastern and western sides of the study area. The comprehensive resilience values are largely influenced by per capita energy-saving and environmental protection expenditures. The restoration zones mainly concentrated in the contiguous regions of the northwestern and southern parts, covering more than half of the total area. The conservation zones are more numerous and primarily situated in the northern and eastern parts. By integrating socio-economic and ecological factors, this study proposes ecological restoration strategies for specific zones. It helps for improve development issues arising from complex interactions between human-environment, facilitating the implementation of restoration practices.

“…The construction of ecological security patterns plays an important role in the ecological restoration of national land space, and the restoration of ecological fragile landscape is the key to constructing regional ecological security patterns [7]. At the present, the general approach of ecological security pattern research is "source identification-resistance surface construction-corridor extraction" [8]. Ecological source areas are regarded as the basis for establishing ecological security patterns, which can be directly selected as nature reserves [9], green areas [10], forest patches, or other important ecological land.…”

The Yellow River Source Area is located in the ecological protection and restoration area of the Sanjiangyuan in China, which has been deteriorating as a result of human-caused overgrazing and the grassland destruction caused by plateau rats and rabbits, as well as the influence of other natural factors. The Yellow River Source Area is an important area that implements ecological restoration and protection in the Three Rivers Source Region, where the ecologically vulnerable areas that are of great significance to the implementation of ecological restoration in national land space should be identified and the early warning should be extended. This measure can help us identify potential ecological problems and take timely and targeted protection measures to ensure the health and sustainable development of the ecosystem in the Yellow River Source Area. Therefore, an in-depth understanding of the ecological vulnerability of the Yellow River Source Area and the establishment of an early warning mechanism are of vital importance for the protection and restoration of the ecology of the national space in the Yellow River Source Area. Aiming to comprehensively delimit ecological restoration areas in the Yellow River Source Area and provide an early warning, this study applies the MSPA method to identify ecological source areas and uses a patch importance index to identify the importance of ecological source areas, along with extracting potential ecological corridors by using the MCR model, screening important ecological corridors by using the gravity model as a criterion, and simulating land cover changes in 2030 under the limitations of ecological security pattern by using the PLUS model. The results show that: (1) 154 potential ecological corridors were extracted based on the MCR model, with a total length of 7891.90. (2) The total area of the landscape types in the Yellow River Source Area was 12,301 based on MSPA analysis, including the 6899.57 of core area. (3) Based on the PLUS model, the area of farmland and forest in the study area will decrease, while the grassland area will increase. According to the studies, the grassland in the study area expands in a circular pattern towards the surrounding wetland and water area, threatening the ecological sources and corridors. In summary, the study delimits one protection zone in the ecological source land and two core ecological restoration zones and points out the early warning points in the ecological protection space. The delimitation and instruction provide specific spatial guidance for the protection and restoration of ecosystems in order to promote ecological sustainability.

“…Spatial zoning of territorial ecological restoration offers the possibility to assess ecological degradation from a spatial perspective, and further provides assistance to enhance ecosystem integrity and sustainability (Cao et al, 2019;Peng et al, 2020). A wide variety of approaches for ecological restoration zoning have been adopted, including depiction of landscape ecological pattern, dominant functional partition and ecological security evaluation, with the goal of achieving targeted remediation and management (Cai et al, 2020;Fu et al, 2020;Ni et al, 2020). As an effective method to assess ecosystem status, ecosystem health assessment can help identify ecological problems by detecting "hotspots" of land degradation and biodiversity loss.…”

Assessments on the spatial pattern of ecological restoration potential provide insights into the current status of ecosystem health, facilitate the identification of hotspots of ecosystem degradation, and further serves as a link that bridges regional ecological planning with specific restoration efforts. The goal of this study was to reconstruct the ecological restoration pattern, through establishing an ecosystem health assessment model encompassing four elements of vigor, organization, resilience and service of an ecosystem. Siping City, a typical black soil region located in central Jilin Province of Northeast China, was selected as the study area, and ecological protection and restoration units were identified based on temporal changes in ecosystem health levels from 2000 to 2020. Getis-Ord Gi* analysis was adopted to classify the restoration zones and depict the spatial pattern of ecological restoration. From 2000 to 2020, the ecosystem health index of Siping City generally increased from 0.49 to 0.51 due to increases in forestland area and precipitation, but a fraction of suburban areas also experienced decreases. Four different restoration zones were delineated, including the windbreak and sand-fixing zone in the western part, the black soil protection and reclamation zone in the middle part, the Daheishan ecological shelter zone in the central and eastern part, and the water restoration zone in the eastern part, which account for 28.12%, 37.05%, 16.53% and 18.29% of the total area. The protection units covered an area of 1,189.83 km2 and the restoration units covered an area of 2009.83 km2, which could be further classified into 10 types and accounted for 31.24% of the total area. It was suggested that the restoration methods applied to different units should be tailored towards specific restoration objectives. This proposed methodological framework serves as a basis for reconstructing ecological restoration in the black soil region, and a reference for making restoration plans elsewhere.
