摘要
基于中国知网(CNKI)中文数据库对国内污染源解析的相关文献进行了计量分析。结果表明,1988年~2020年间,污染源解析相关的研究逐年增加,数据库中最早的污染源解析相关文献发表于1988年,主要是利用等离子体发射光谱分析北京市5个采样点的小颗粒物化学成分,并将其结果应用于化学质量平衡法解析污染源。2007年以前,污染源解析相关文献每年不超过10篇,自2010年以后,该领域内相关研究论文直线增加。目前,以污染源分析、农田土壤重金属、地表水污染为中心目标,科研人员主要聚焦寻求高效的解析方法,包括多元统计分析、PMF指数法、空间分析等,其中污染源的分布是目前的研究热点。
Based on the Chinese database of China Knowledge Network (CNKI), the relevant literature on domestic pollution source analysis was analyzed quantitatively. The results showed that from 1988 to 2020, research related to pollution source analysis increased year by year. The earliest pollution source analysis related literature in the database was published in 1988, mainly using plasma emission spectroscopy to analyze the chemical composition of small particles at 5 sampling points in Beijing. The results are applied to the chemical mass balance method to analyze pollution sources. Before 2007, there were no more than 10 literatures related to pollution source analysis each year. Since 2010, related research papers in this field have increased linearly. At present, with pollution source analysis, farmland soil heavy metals, and surface water pollution as the central goals, researchers mainly focus on seeking efficient analytical methods, including multivariate statistical analysis, PMF index method, and spatial analysis. Among them, the distribution of pollution sources is the current research focus.
