“…Xue (Xue, 2023) used the Zhangjiakou section of the Beijing-Zhangjiakou Railway as a typical case, establishing an index system for ecological environment quality, landscape pattern, and carbon storage, evaluating the ecological impact of the railway corridor, and analyzing the ecological costs and benefits of the railway corridor from an economic perspective. Yang (Yang, 2023), based on the RSEI model, took the city of Poland along the route of the China-Europe freight train as an example, analyzing the spatiotemporal changes in the ecological environment at the urban scale before, during, and after the operation of the China-Europe freight train. Focusing on the Xinjiang section of the Lan-Xin Railway Project, this research aims to fill this gap.…”

Introduction: Vegetation is the main factor of ecological stability, but the construction of largescale corridor projects will bring some damage to vegetation.Methods: Based on the NDVI, temperature and precipitation data of the growing season from 1990–2021 (June to September), this paper uses the maximum synthesis method, trend analysis method, correlation analysis method and coefficient of variation method to study the spatial-temporal changes and driving factors of NDVI in the past 32 years, taking the 30 km belt buffer zone along the Lan-Xin Railway as the research area. The influence range of railway construction on NDVI in different climatic conditions is analyzed.Results: The results showed that: (1) From 1990–2021, the average annual temperature of the growing season in the study area showed an increasing trend, the average annual precipitation showed a decreasing trend, and the average annual NDVI showed an increasing trend; NDVI was positively correlated with temperature in 54.04%, and positively correlated with precipitation in 62.88%. Precipitation had a greater effect on NDVI than temperature. (2) Under the same climatic conditions, the NDVI variability coefficient in the study area fluctuates significantly within 3,000–21,000 m along the railway line, stabilizing beyond 21,000 m; the impact range of railway construction on NDVI gradually increases with increasing precipitation within the same temperature range, and increases gradually with rising temperatures within the same precipitation range. (3) During the growing season (June to September) in the study area, when the temperature is below 25°C, NDVI increases initially with increasing precipitation before decreasing, showing an overall upward trend; when the temperature is above 25°C, NDVI initially increases with increasing precipitation before decreasing. High temperature and high precipitation will inhibit vegetation growth and reduce NDVI. The NDVI of the core area before the railway construction is larger than that of the background area, while the NDVI of the core area after the railway construction is smaller than that of the background area.Discussion: In short, the construction of Lan-Xin Railway has a certain influence on NDVI along the line. When studying the impact of large-scale engineering projects on vegetation in the future, higher resolution imagery can be used along with the incorporation of human activities' influence. These factors will enable more accurate and comprehensive research.

“…So, the areas along the cross-border transportation route have become typical areas for a complete cross-border HLS [20]. However, the construction of transportation routes, rapid economic expansion, and frequent migration of people damage the ecological environment profoundly [21,22], and the vulnerability of the HLS to cross-border regions is becoming increasingly acute [23]. It is quite urgent to carry out scientific prevention of ecological risks and propose countermeasures to ensure sustainable ecological and economic development in cross-border regions.…”

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.
