The purpose of this paper is to analyze the international land reclamation research focus and trend based on the statistical analysis of 31 years’ proceedings of the Annual Meeting of the American Society of Mining and Reclamation. Divided into three periods, the key words in the proceedings have been analyzed by VOSviewer, a bibliometric mapping software. The results show: 1)the cluster analysis has divided the key words into three clusters, “land reclamation evaluation, planning and management”, “acid mine drainage” and “soil and vegetation”; 2)the key words are stable with subtle changes, and the amount increases gradually. We conclude that the research became more specific, the research objects became more diverse, and connotation extended consistently. Besides, the innovative reclamation notions, techniques and materials sprang up. It is clearly that the ecology impact and its research methods have become and will continue to be the focus.%研究目的：通过对美国采矿与复垦学会31次年会论文集的统计分析，以求解析国际土地复垦领域的重点问题及发展趋势。研究方法：采用VOSviewer可视化文献分析软件，划分三个时间段对会议文献的关键词进行统计和聚类分析。研究结果：根据聚类分析结果将关键词划分为“复垦评价、规划与管理”、“酸性矿井水”和“土壤与植被”三个聚类，在三个时间段中，各聚类的关键词在稳定中有变化，数量逐渐增多。研究结论：土地复垦的研究对象更加丰富，复垦的内涵与外延在不断扩展，研究进一步细化。新理念、新技术、新材料不断涌现，生态问题成为研究的重点，也是未来研究的趋势。
