“…Others contraposed extreme terrain areas such as the Qinghai Tibet Plateau [5,37] to explore the spatial distribution pattern, driving factors and spatial heterogeneity of ecological vulnerability. Karst landform areas [38], tropical ecosystems [39] and water environment systems [40] were bought into ecological vulnerability as well. Nevertheless, there are few studies on ecological vulnerability evaluation in provincial administrative regions.…”

As China’s main grain-producing region, the ecological security pattern of Liaoning Province has an extremely important impact on the ecological security of Northeast China and even the whole country. Furthermore, the construction of the ecological security pattern is restricted by the ecological vulnerability assessment in order to explore the ecological vulnerability pattern of spatial distribution and the trend of future vulnerability development in Liaoning Province and guide how to formulate ecological protection policies scientifically. Based on the sensitivity–resilience–pressure (SRP) conceptual model which is combined with natural and socio-economic factors, the ecological vulnerability evaluation index system of Liaoning Province is established in this paper. This paper also evaluates the ecological vulnerability of Liaoning Province from 2010 to 2020 and analyzes the driving factors by using a geographic detector and the CA-Markov model. Moreover, the study forecasts the growing tendency of vulnerability in 2025. The results show that (1) the ecological vulnerability of Liaoning Province is mainly light and has medium vulnerability, which gradually decreases from northwest to southeast; (2) the spatial heterogeneity of the ecological vulnerability index (EVI) is very significant in the southeast and northwest region but not significant in the middle; (3) from the past decade to the next five years, the ecological vulnerability of Liaoning Province has been improving, and the overall distribution pattern of ecological vulnerability is relatively stable; (4) the analysis of driving factors indicates that the impact of natural environmental factors such as land-use type and habitat quality on EVI is more significant than socio-economic factors such as population density. The research results implicate that it is necessary to formulate an ecological protection and restoration plan in Liaoning Province to prevent further ecological degradation in high-value areas of northwest Liaoning, and to balance the relationship between human development and ecological protection and restoration in the metropolitan district.

“…Yue Chen et al compared the similarities and differences in the vulnerability of karst and non-karst areas [16]. In addition, some researchers have chosen tropical ecosystems [17], aquatic environmental systems [18], and cropland systems [19] to examine the vulnerability patterns. However, few current studies have selected cross-border regions as the study area, which will become the focus area for research in the future.…”

In recent years, the conflicts of the human–land coupling system (HLS) in the cross-border transportation corridor areas have become increasingly severe, especially in the China–Mongolia–Russia Cross-Border Transportation Corridor (CMRTC). The vulnerability assessment of the HLS-CMRTC is the key scientific issue for regional sustainable development. Based on the nearly 20 years of a scientific expedition, we set the CMRTC as the study area, constructed the vulnerability assessment index system and quantitative model, assessed the vulnerability of the HLS-CMRTC, revealed the key influencing factors, divided vulnerability risk prevention zones, and proposed the targeted optimization countermeasures. This study found that: (1) The overall vulnerability pattern of the HLS-CMRTC showed a vulnerability level gradually increasing from south to north. (2) Permafrost instability risk, land desertification, temperature increase, and backward social development were key influences. (3) Vulnerability risk prevention zones were divided into four priority and two general zones. The targeted optimization countermeasures were proposed, such as establishing an ecological security barrier, carrying out collaborative ecological risk monitoring, and early warning. The conclusions could provide a decision-making basis for the study area to reduce the vulnerability of the HLS. They could also provide reference and scientific support for achieving sustainable development of the economy and environment in similar regions of the world.
