“…However, this method only uses the proportion of different land-use areas as the weight, leading to a lack of representation of ecological factors in risk probabilities [27]. Meanwhile, some studies have applied a "source-sink" method to evaluate specific risk sources, such as population growth and heavy metal contamination [28,29]. However, as this method is difficult to characterize the risk status of multisource stress, it reflects the comprehensive characteristics of LER in a relatively weak manner.…”

Land use in traditional village clustering areas often exhibits slight dynamic changes; however, significant hidden ecological hazards may be present in local settlements. There is still a lack of dynamic ecological risk assessments for the corresponding classification-based prevention strategies and landscape ecosystem attributes’ enhancement. Based on the land-use changes, this study integrated the ecosystem structure and function to explore the characteristics of the landscape ecological risk in traditional village clustering areas. The clustering area of 24 national traditional villages in Songyang County of Lishui City in Zhejiang Province, China, served as the study region to evaluate and analyze the changes in the landscape ecological risk from 2010 to 2019. The results showed that the land-use transitions were subtle but dominated by changes from forest cultivated land, posing high risk and medium—high risk increased slowly in size. Additionally, significantly increased risks were located mainly in the boundary area of the five villages. Moreover, 22 settlements were found in the sensitive area with increased risks less than 600 m away. This assessment will provide a basis for traditional villages’ risk prevention and ecosystem protection.

The analysis of the impact on the ecology of the state of cybersecurity of critical infrastructure objects and the factors influencing the state of cybersecurity of the information system of the critical infrastructure object is performed. An explanation is given of why cybersecurity violations in automated process control systems can lead to consequences in the industrial sector and environmental impact. The need to develop effective and adequate proposals and measures for cybersecurity of information systems of the critical infrastructure objects is shown. The classification of assets that are the objects of cyberattacks by attackers and the categories of impact on the critical infrastructure objects are given. Approaches to determining the cyber threat risk factor of the critical infrastructure object and the relevance of threats are presented. The method of assessing the degree of possible damage from the implementation of information security threats is considered. The results of this analysis can be used to develop proposals and measures to avoid the effects of cyberattacks on the critical infrastructure objects. The prospect of further research is to develop a methodology for determining the relationship between specific cyberattacks and possible quantitative damage.

“…The study area has involved desert oasis [39], plateau [40], mountainous area [41], estuary delta [42], watershed [43,44], urban agglomerations [45,46], and other different types of regional spaces. In terms of research topics, many scholars have focused on the structure of ecological networks [25,28], identification of ecological networks [47,48], ecological network evaluation [45,49], and ecological network optimization measures [36,50] conducted in a series of studies. Among the functional components of the ecological network, scholars pay more attention to the identification of the ecological sources and the construction of the ecological corridors.…”

“…The first type is the direct determination method, that is, the nature reserve [51], urban green space [52], and regional land cover types [15] are directly selected as ecological sources. The second type is the model evaluation method, which identifies ecological sources through ecosystem service supply and demand measurement [53], key ecosystem service analysis [54,55], ecological risk assessment [47], granularity reverse method [56], ecological sensitivity assessment [57], MSPA [29,35], and other evaluation methods. Most studies on the extraction of the ecological corridors were based on land-use types to construct comprehensive resistance surfaces and then used the minimum cumulative resistance model to generate potential ecological corridors.…”

Rapid urbanization and drastic land-use change have led to landscape fragmentation and ecological environment deterioration in the regions along the Grand Canal. Building an ecological network is an important means to improve the connectivity of habitat patches and carry out ecological protection and restoration of territorial space, which is of great significance to ensure regional biodiversity and ecological security. In this article, we took the Huaiyang Section of the Grand Canal (Huaiyang Canal) as the study area, used the ecosystem service assessment model, morphological spatial pattern analysis (MSPA), and the landscape connectivity evaluation method to identify ecological sources, then used the minimum cumulative resistance (MCR) model and the gravity model to extract and grade ecological corridors. Based on these, the ecological network was constructed by combining the identification method of ecological nodes and ecological breakpoints. The aim of this was to provide a reference for the ecological space optimization of Huaiyang Canal and even the entire Grand Canal, the formulation of an ecological protection plan, and the implementation of territorial space ecological restoration. The results showed that the spatial distribution of the water conservation service, soil conservation service, carbon sequestration service, and biodiversity conservation service were significantly different, and the level of ecosystem services showed a trend of continuous degradation from 1990 to 2018. There were 12 ecological source patches comprehensively identified by multiple methods, with a total area of 2007.06 km2. In terms of spatial distribution, large ecological source patches were mainly distributed in the central and western areas adjacent to the Grand Canal, while small ecological source patches were scattered in the eastern and southern border regions of the study area. The total length of ecological corridors was 373.84 km, of which the number of the primary ecological corridor, secondary ecological corridor, and tertiary ecological corridor were 9, 7, and 7, respectively, and the suitable width of the ecological corridor was 200–400 m. After optimization, the proposed ecological network was composed of 3 key ecological source patches, 9 important ecological source patches, 23 terrestrial corridors, 10 aquatic corridors, and 18 ecological nodes. Twenty-nine ecological breakpoints were key areas requiring ecological restoration. The overlap rate of the integrated ecosystem service change area and land-use change area was 99%, indicating that land-use change has a significant impact on regional ecosystem services. This study is of great significance for carrying out the ecological protection and restoration of the Huaiyang Canal and adjusting local land-use policies. It also provides a typical case demonstration for identifying an ecological network and formulating ecological restoration planning for other sections of the Grand Canal and cities along the canal.
