我国粉煤灰作为改良材料研究现状及展望——基于CNKI数据库文献分析

Research Status and Prospects of Fly Ash as Improved Materials in China—Based on CNKI Database Literature Analysis

摘要: 为了客观全面地分析我国粉煤灰作为改良材料用于工农业生产方面的发展脉络和研究动态，本研究利用CNKI中国期刊全文数据库的出版年份、论文数量、研究机构、资助资金等多个指标，系统阐述我国粉煤灰作为改良材料再利用的研究状况，综合分析该领域的主要热点和趋势。结果表明：发表相关研究最多的机构是中国地质大学；粉煤灰领域研究主要受到国家自然科学基金的引导；被引用频次最高的期刊为《生态环境》，该论文来自土壤与农业可持续发展国家重点实验室/中国科学院南京土壤研究所陈义群教授；我国粉煤灰再利用的热点主要集中在土壤改良、改良土、无侧限抗压强度等方面。总的来说，我国粉煤灰改良研究以交通运输、环境保护、建筑科学和农业资源与环境为主，并且有向环境保护方面发展的趋势。

Abstract: In order to objectively and comprehensively analyze the development and research dynamics of China’s fly ash as an improved material for industrial and agricultural production, this study uses the publication year of CNKI China Journal Full-Text Database, the number of papers, research institutions, funding funds and other indicators. This paper systematically expounds the research status of fly ash as a modified material in China, and comprehensively analyzes the main hot spots and trends in this field. The results show that the institution which published the most related researches is China University of Geosciences; the research on fly ash is mainly guided by the National Natural Science Foundation; the most frequently cited journal is “Ecological Environment”, which is from the soil and agricultural sustainable development countries key laboratory/Chen Yiqun, Institute of Soil Science, Chinese Academy of Sciences; China’s fly ash reuse hotspots are mainly concentrated in soil improvement, improved soil, and unconfined compressive strength. In general, the research on the improvement of fly ash in China is mainly based on transportation, environmental protection, building science and agricultural resources and environment, and has a tendency to develop towards environmental protection.
