Research status and development trend of soil organic matter in black soil based on bibliometric analysis
Black soil is one of the important cultivated land resources in China,and the content of or-ganic matter has an important impact on soil quality and crop yield.This paper uses bibliometrics analysis method to summarize the current situation and development trend of black soil organic matter research in my country by collecting and analyzing the number of published papers,journal sources,authors,research institutions,keywords and abstracts,and reveals the concerns of this field.Focus and research hotspots.The results show that the research on black soil organic matter in my country is on the rise;scientific re-search institutions and universities are the main research forces,and the Northeast Institute of Geography and Agroecology of the Chinese Academy of Sciences and Northeast Agricultural University are in the leading position in black soil related research;Class analysis and co-occurrence analysis.Research in this field mainly focuses on soil organic matter content,soil model and remote sensing technology,organic matter decomposition and transformation,and the impact of organic matter on soil texture and nutrients.In the future,multidisciplinary cross-cooperative research should be strengthened,focusing on topics such as the dynamic change mechanism of black soil organic matter,multi-scale,and multi-period remote sens-ing monitoring technology.
