Bibliometric Analysis of Soil Enzyme Research Literature Based on CNKI Database

Objective  This paper was aimed at finding out the research hotspots and trends of soil enzymes in China in recent years.

Method  Based on CNKI database and its bibliometric tools, with the help of CiteSpace software, statistical and cluster analysis methods were used to visually analyze the amount of papers, institutions, disciplines, topics and keywords of domestic soil enzyme research literature.

Result  Soil enzymology integrated with ecology, agriculture and forestry science, environmental science and other disciplines in China is still in the stage of rapid development. Domestic soil enzyme researches are mainly supported by the national projects, agricultural universities are the important forces for the researches, and the exchanges and cooperation among various institutions are relatively close. Soil enzyme activity, soil microorganism and soil fertility have always been the focus of soil enzyme research. At present, soil enzyme researches in China mainly focus on the following three directions: the effects of different fertilization and agricultural measures on improving soil enzyme activity and nutrient utilization efficiency; improving soil microecology and microbial community structure to solve agricultural production problems; applying molecular biology technology to improve the experimental analysis level of soil enzyme research.

Conclusion  The bibliometric analysis results will help to fully understand the current situation and progress of soil enzyme researches in China, and provide references for the subsequent soil enzyme research.
