“…Coupling, as a physical concept, refers to the phenomenon where two (or more) systems interact with each other and affect each other [18,19]. When the alignment design system and the resource environment system interact and influence each other, this coupling forms an "alignment design-resource environment" composite system.…”

“…According to Formulas (18) and (19), the degree of obstacles to the collaborative development of the U-L composite in the internal system elements and external system elements can be calculated. Based on this, the obstacle degree of the indicator layer is calculated for the elements with high obstacle degrees in the internal and external systems (Figure 12).…”

Faced with the characteristics of multifactor coupling and interweaving along the railway lines in the southwestern mountainous areas of China, researching the coupling mechanism and optimizing the collaborative development path between alignment designs and the resource environment is conducive to promoting the green and sustainable development of railways in these southwestern mountainous areas. In this study, first, regarding the environmental characteristics of engineering along the railway lines in the southwestern mountainous area, the key elements of the interaction and coercion between the alignment design (internal system) and the resource environment (external system) are identified, and the interactive impact mechanism of the “alignment design–resource environment” complex is revealed. Accordingly, a nonlinear coupling mechanism between the alignment design system and the resource environment system is established using the deviation coefficient coupling degree model. Second, from a methodological perspective, following a technical path of “analyzing the coercive effects of internal and external factors–identifying coupling relationships–discovering coupling laws–screening driving factors–proposing optimization plans–achieving collaborative development goals”, we propose an overall optimization plan to solve the problem. Finally, the Chengdu Changdu section of the X railway, which is located in a southwestern mountainous area, is taken as an example for this study. The results indicate that if the state of the external system of the KL scheme is continuously improved through the regulation of the u22 (crossing the ecological protection red line length), u23 (biodiversity impact), and u24 (ecosystem impact) indicators and that the internal structure of the line design is improved by optimizing the l12 (total length of bridges and tunnels) and l13 (number of stations) indicators, effectively driving the improvement in the u31 (land resource occupation) and u43 (land development intensity) indicators, the alignment design and resource environment will exhibit a mutually reinforcing coupling evolution trend and ultimately achieve an “alignment design–resource environment” composite system with higher quality coupling.

“…Researchers offer various models that optimize sustainability in the linkage of "waterenergy-food" [22,23]. Optimization of this relationship is most often considered by researchers in terms of solving the problems of the water crisis in agriculture [24,25], to increase the sustainability of the development of various sectors of industry [26] and urban agglomerations [27,28]. As noted by L. Wu et al, the essence of the "water-energy-food" concept is expressed not only in the need to find compromise solutions but also in the direction of interaction that provides synergy depending on the policy being developed [24].…”

The growing negative anthropogenic impact on the environment causes scientific interest in the problems of water management. The increasing number of publications in this scientific field requires their intellectual systematization. The purpose of this study is to conduct a bibliometric review of scientific publications related to water management issues in the context of solving the problems of increasing the sustainability of the socio-economic development of a region for better understanding of current research trends. To achieve this goal, bibliometric analysis using the VOSviewer software product (Manual for VOSviewer version 1.6.17) was used. The international database Scopus was taken as the source of information. This study examined 10,208 articles on water management issues from 2012 to 2022. The basic criterion for including a publication in the selection was that the topic of the work belongs to the subject areas of economics, econometrics and finance and business, management and accounting. As a result of the analysis, it was determined that the problems of water resources management have not lost their popularity in the global research community and the research methodology is evolving towards the concept of “water–energy–food”. The centers of knowledge forming the vector of scientific research are the USA and the Netherlands; however, in recent years, the research of Chinese scientists has become increasingly important. It is concluded that the potential for the development of research in the field of water resources management in the context of solving the problems of the sustainable development of regions is associated with the search for opportunities for revealing the synergy of intersectoral interactions while taking into account their sectoral and regional specifics.
