| 【目的】探明我国近年土壤酶的研究热点与趋势。【方法】基于 CNKI 数据库及其文献计量工具，
借助 CiteSpace 软件，采用统计与聚类等分析方法，对国内有关土壤酶研究文献的发文量、机构、学科、主题和
关键词等方面信息进行可视化分析。【结果】我国土壤酶学与生态学、农林科学和环境科学等学科融合，目前
仍处于高速发展阶段。国内土壤酶研究主要来源于国家项目支持，涉农高校是研究的重要力量，各机构之间交
流合作较为紧密。土壤酶活性、土壤微生物和土壤肥力一直是土壤酶研究的关注热点，目前国内土壤酶研究主
要围绕以下 3 个方向：不同施肥和农事措施对提高土壤酶活性和养分利用效率的影响；改善土壤微生态和微生
物群落结构，解决农业生产问题；应用分子生物学技术提高土壤酶研究的试验分析水平。【结论】计量分析结
果有助于全面了解国内土壤酶研究现状及进展，为土壤酶研究提供参考。 |

| 【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. |
