其他摘要 | In order to understand the research progress of soil carbon sequestration and provide references data for
relative researchers, this paper used the methods of Web of Science DSN and data base with build-in profiler
Thomson Data Analysis (TDA), Society network analysis and visualization tools Netdraw and Ucinet, progressed the
metric analysis of papers on carbon sequestration and its influencing factors published from 1992 - 2015, especially in
recent decade, from six aspects as annual change trend of thesis, global powerful countries in relative research,
organization distribution and force comparison, grant-giving agency and their theme distribution, institute cooperative
and research content. The results showed that: (1) The number of papers was on a steady growth trend. The researches
of soil carbon sequestration and soil microbial diversity mainly were focused on Europe and the United States and
other developed countries (regions). The highest comprehensive influence of paper was occurred in United States and
Germany. Higher citations per paper was mainly in Britain, Sweden, Switzerland, and Netherlands. The most research
papers in this field were published by Chinese research institutions represented by Chinese academy of sciences. (2)
The highest cited papers were mainly supported by National Science Foundation, followed by German research
foundation, and Chinese academy of sciences foundation. Each country had their own special research theme based on
public economic support. Some research institutions in America were the center of global research cooperation and
communication in this field, followed by in Germany and Chinese academy of sciences. (3) Soil organic matter, soil
organic carbon, nitrogen, phosphorus, microbial biomass, soil properties, climate change and carbon fixation had
become hot research topics in this field in recently 10 years. Future research should focus on the topics on litter
decomposition, heavy metals, microbial respiration, and strengthen international cooperation in order to improve
Chinese research level and solve practical problems with the relative research achievement. |
