Abstract: Soil erosion is a critical environmental challenge with far-reaching implications for ecosystem stability, agricultural productivity, and water quality. Nowhere is this issue more pronounced than in the large river basins of China, where rapid urbanization, agricultural intensification, and climate change converge to exacerbate soil erosion processes. This study aims to present our research findings to elucidate the evolution patterns of soil erosion in China’s large river basins against the backdrop of a changing environment. The evolution of soil erosion in these river basins is a multifaceted phenomenon influenced by various interconnected factors. Climate change, characterized by altered precipitation patterns and increased frequency of extreme weather events, significantly impacts soil erosion dynamics by intensifying rainfall erosivity and altering vegetation cover. Moreover, human activities, including deforestation, land use change, and inappropriate agricultural practices, further exacerbate soil erosion rates, particularly in vulnerable regions with steep terrain and fragile ecosystems. Understanding the spatial and temporal patterns of soil erosion is crucial for effective land management and conservation strategies. Remote sensing techniques, geographic information systems (GIS), and modeling approaches have been instrumental in assessing soil erosion dynamics across different scales. These tools enable the identification of high-risk areas and the evaluation of the effectiveness of soil conservation measures. Several studies have highlighted the significance of vegetation cover in mitigating soil erosion by stabilizing slopes, reducing surface runoff, and enhancing soil infiltration capacity. Forest restoration programs and agroforestry practices have shown promising results in reducing soil erosion rates and improving soil quality in degraded areas. However, the success of these interventions depends on various factors, including site-specific conditions, land tenure systems, and socio-economic drivers. The management of soil erosion in large river basins necessitates a holistic approach that integrates ecological, social, and economic dimensions. Sustainable land use planning, erosion control measures, and incentive mechanisms are essential components of integrated watershed management strategies. Furthermore, fostering community participation and stakeholder engagement is vital for promoting local ownership and ensuring the long-term sustainability of conservation initiatives. In conclusion, the evolution patterns of soil erosion in China’s large river basins reflect the complex interplay of environmental, climatic, and anthropogenic factors. Addressing this challenge requires.
