根据1932 - 2013年SCI数据库中与土壤侵蚀相关的出版物，揭示了土壤侵蚀研究的科学产出、主要学科类别、地理分布和研究热点，为今后的研究提供了潜在的指导。在过去80年中，每年出版物的数量呈增长趋势，1990年后增长尤为迅速。农业、环境科学与生态学、地质学和水资源学是四大类。土壤侵蚀的跨学科研究越来越普遍。2001年以前，土壤侵蚀研究主要分布在美国和欧洲，2001年以后，中国和澳大利亚土壤侵蚀研究蓬勃发展。美国是全球土壤侵蚀研究的最大贡献者。近十年来，我国对土壤侵蚀研究的重视程度仅次于美国.中国科学院是最多产的研究机构，其次是美国农业部农业研究服务和鲁汶天主教大学。关键词分析证实了对产沙量、土壤有机碳和磷的浓厚兴趣;表明降雨径流、气候变化、农业耕作和土地利用变化是土壤侵蚀的主要原因;揭示了GIS、遥感、模型和Cs-137测量的重要作用;并发现中国中北部的黄土高原是研究重点。通过共引分析，土壤侵蚀研究主要集中在基于模型的土壤侵蚀模拟、基于Cs-137技术的土壤侵蚀估算以及土壤侵蚀对环境和农业的影响三个方面。
According to the publications related to soil erosion in the SCI database from 1932 to 2013, this study reveals scientific outputs, main subject categories, geographical distribution, and research hotspots in soil erosion studies, which may be considered a potential guide for future research. The annual number of publications showed an increasing trend over the past 80 years, with an especially rapid increase after 1990. Agriculture, environmental sciences and ecology, geology, and water resources were four major categories. Interdisciplinary research in soil erosion is becoming more common. The soil erosion research was mainly distributed across the USA and Europe before 2001 and boomed in China and Australia after 2001. USA was the largest contributor to global soil erosion research. China is focusing increasing attention on soil erosion research in the last decade, behind the USA. The Chinese Academy of Sciences is the most productive institute, followed by USDA Agricultural Research Service and Katholieke Universiteit Leuven. A keyword analysis confirmed keen interest in sediment yield, soil organic carbon, and phosphorus; indicated that rainfall runoff, climate change, agricultural tillage, and land use change were the leading causes of soil erosion; revealed the important role of GIS, remote sensing, model, and Cs-137 measurement; and found that the Loess Plateau of north-central China was an area of research focus. Through co-citation analysis, soil erosion research mainly focuses on three aspects: soil erosion simulation based on models, soil erosion estimation based on Cs-137 technique, and effects of soil erosion on the environment and agriculture.
