Abstract: Research papers on Chernozem or Mollisols(Black soils) in the last 100 years were analyzed using Thomson Data Analyzer(TDA) software and detailed literature information from 2951 papers obtained by science citation index expanded(SCIE) in the years of 1928-2012.Development trajectory of research on Chernozem was revealed from the perspectives of annual publications and citations,research institutions,authors and funding agencies.Six major research issues on Chernozem were acquired by analyzing comprehensive key words,they were yield/production,fertilization/fertilizer,tillage/farming,soil organic matter/soil organic carbon,soil erosion/soil degradation,soil properties/soil characteristics.According to the analysis of highly cited papers and research fronts,the stability mechanism of soil organic matter was the hot issue,while research related to soil organic carbon is still a major scientific issue in Black soil research in the years to come.
