| 为探明我国近年土壤酶的研究热点与趋势，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了可视化分析。研究表明，我国土壤酶学与生态学、农林科学和环境科学等学科融合，目前仍在高速发展阶段。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三个方向：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。该研究有助于全面了解国内土壤酶研究现状及进展，为接下来的土壤酶研究提供参考。 |
| 英文摘要: |
| In order to find out the research hotspots and trends of soil enzymes in China in recent years, 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.The results show that soil enzymology in China is still in the stage of rapid development, which is integrated with ecology, agriculture and forestry science, environmental science and other disciplines.Domestic soil enzyme research mainly comes from the national project support, agricultural universities are an important force in the research, 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 research in China mainly focuses 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. This study will help to fully understand the current situation and progress of soil enzyme research in China, and provide a reference for the next soil enzyme research. |
