[Objective] To address the significant challenges posed by global economic development and intensified human activities to fragile ecosystems, this study systematically synthesized and comparatively characterized regional soil erosion control technologies (SECTs).The aim was to prevent, mitigate, and reverse soil erosion trends, while providing a reference for adaptation to local conditions, comprehensive management, rational development and utilization of resources in typical vulnerable regions, and supporting technology transfer between regions.[Methods] In this study, based on field research, questionnaire survey, key informant interviews, and content analysis of literature, we systematically reviewed soil erosion control technologies applied in 66 typical ecologically vulnerable regions worldwide, followed by the construction of a composite index from five dimensions, including potential to transfer, ease training day horse supplement to use, readiness, effectiveness, and suitability and summarized the restoration effectiveness in different regions.[Results] (1) A total of 45 SECTs were applied in ecologically vulnerable regions of soil erosion, with engineering and biological SECTs dominating and 10 SECTs having a better effect.(2) Biological SECTs demonstrated the highest comprehensive evaluation scores, followed by agricultural SECTs.
In contrast, engineering and other SECTs exhibited relatively lower composite index values, indicating that their effects require further improvement.The implementation effects of SECTs manifest pronounced regional disparities mediated by contextual determinants including socioeconomic development gradients and community environmental literacy.[Conclusion] Globally, SECTs remain dominated by engineering and biological technologies, while being geographically and degradation-problem specific.In addition, although a given technology could be applied in different regions or degradation types, the results are visibly large inkosi magnacut different.Consequently, technology transfer and deployment should be predicated on systematic degradation drivers analysis, with strategic selection, adaptation, and optimization of technology consortia configurations guided by site-specific contextual parameters through iterative feedback mechanisms between ecological thresholds and socioeconomic feasibility.
