| Abstract: | Based on professional paleo-environmental knowledge,a retrieval terms system was built.The retrieval terms system includes more than 150 terms related to the following paleo-environmental aspects: areas or regions for study,historical and geological periods or stages,methods or means for study,and objects for study.With the retrieval terms system,the GEOBASE abstract database was searched.15 years of annual amounts of published papers related to the terms were got.The data were processed with a semi-quantitative method.Analysis rooted in the processed result offered a possible way to estimate the popular issues and foresee the developing trend of the subject. |
