| 摘要: |
| 为全面了解国际土壤学界研究动态，把握学科发展方向，以SCIE中收录的3种土壤学综合类国际期刊2003—2012年刊载的论文为数据源，采用CAB农学与生物学叙词表，通过高频主题词共现聚类确定了近10年来土壤学的15个研究领域，利用战略坐标图揭示了各研究领域的学科地位，采用文献计量方法和社会网络分析方法对比了前10个（TOP10）国家、前10名（TOP10）研究机构的实力和布局情况，并特别针对我国的核心研究机构和主题聚焦情况展开讨论，提出我国未来土壤学研究应加强的方面和重点布局的主题领域。 |

| Abstract: |
| In order to profile research status of soil science and gasp development direction of the subject,based on the articles of three soil science journals published in 2003—2012 and catalogued by SCIE and assisted with CAB Thesaurus,the subject co-occurrences of high-frequency were counted in this paper and divided into 15 research fields.The characteristics of the 15 research fields were analyzed.Then the subject concentrations in TPO10 countries and TOP10 research institutes were compared and Chinese soil science research status was specially profiled.Finally,some suggestions for Chinese soil science research were put forward. |
