Abstract [Background] Land degradation is one of the most critical environmental problems in the world. Soil erosion, a vital cause of land degradation, has been engaged more attention. Vegetation has become an important measurement for soil erosion control and sediment yield reduction. Current studies cannot fully meet the scientific and technological needs of scientific distribution and optimal distribution in the process of vegetation restoration to achieve the optimal eco-economic effect. At present, the impact of vegetation type and quantity on soil erosion and sediment yield has been relatively clear. However, how vegetation landscape patterns influence soil erosion and sediment yield is still unclear, which has become a hotspot.[Methods] CiteSpace, a bibliometric analysis tool, was used to analyze articles published between 2005 and 2020. All the articles were searched from the Web of Science Core Collection with subject "vegetation" "landscape pattern" "soil and water loss" and "erosion". Basic data, for example, articles number, nationality, the title of publication, institution, author, keywords, and burst time were statistically analyzed. Cluster analysis was carried out on the results, and the burst period of keywords was calculated. Combining with typical reports and reviews, the current situation and progress of assessment model methods, eco-hydrological effects, and coupling of different factors were reviewed. Suggestions for the trend of promoting this research topic were summarized in those bases.[Results] The number of published articles was increasing year by year. Keywords that were still in the burst period in 2020 were related to eco-hydrology. These keywords indicated that researchers were focusing on quantifying vegetation patterns and their internal structure. The key points of research from 2005 to 2020 were model evaluation, eco-hydrological benefits, and coupling factors. These studies were aimed to reveal the process and mechanism of vegetation patterns affecting erosion and sediment production and to quantify its relationship, and then to improve the prediction accuracy of the model or optimize the regulation mode, which may provide a basis for land use management and ecological environment governance. In the future, more attentions should be paid to 1) improve the connectivity theory and related indicators, and clarifying the process mechanism of erosion affected by vegetation patterns; 2) strengthen the optimization of models and optimize the characterization indices, and then to promote the ability of simulating the sediment responses to vegetation patterns; 3) focus on the balance of coupling factors and function, enriching the research connotation.[Conclusions] Vegetation pattern affects the local hydrological process by changing the local sediment connectivity and plays an important role in reducing erosion. The concept of connectivity introduced into related research will provide new perspectives to the study on the response of sediment to vegetation pattern changes. In the future, it is necessary to improve the relevant indicators, to improve the accuracy of the model, and to emphasize the coupling influence and function weight.
