基于文献计量分析的农村生活污水处理研究态势解析

基于Web of Science（WoS）和中国知网（CNKI）科学文献，运用文献计量统计和可视化方法，对25年农村生活污水处理研究领域发文量、主要发文国家、主要作者和关键词等指标进行分析。1995-2019年WoS和CNKI数据库分别收录该领域文献883篇和584篇。WoS中的文献涉及全球64个国家，其中中国发文量占总发文量的22.2%，领先于欧美发达国家。主要发文作者方面，中国学者吕锡武在WoS和CNKI数据库中发文量累计达到22篇，位居全球榜首。综合WoS和CNKI数据库，"污水处理""农村生活污水"和"人工湿地"为文献高频关键词，表明该领域的核心内容是一直围绕农村生活污水的处理和常用处理工艺人工湿地研究。近25年来，农村生活污水处理研究领域主要从早期污水处理工艺选择和应用、目标污染物去除效果以及处理设施运行成本等方面逐步过渡发展到微生物群落角度揭示去除机理、GIS解析源头以及与农村人居环境整治的相互作用关系等方面。

BIBLIOMETRIC ANALYSIS OF RESEARCH TRENDS ON RURAL WASTEWATER TREATMENT

Based on the web of Science (WoS) and CNKI scientific literature, using bibliometric statistics and visualization methods, research indicators of rural domestic sewage treatment in the past 25 years were analyzed, induding the amount of papers, main countries, research institutions, source publications, main authors and key words. From 1995 to 2019, 883 and 584 literatures from WoS and CNKI database were collected respectively in this field. The documents in WoS involve 64 countries in the world, and the amount of Chinese publications accounted for 22.2% of the total number of publications, leading the developed countries in Europe and America. In terms of major contributors, Lü Xiwu, a Chinese researches, had published 22 articles in the WoS and CNKI databases, ranking first in the world. Wastewater Treatment, Rural Domestic Sewage and Constructed Wetlands were the high-frequency key words in the literature, indicating that the core content of this field was rural domestic sewage treatment, and commonly used treatment process of constructed wetland. In the past 25 years, the research field of rural domestic sewage treatment had gradually developed from the aspects of early sewage treatment process selection and application, target pollutant removal effect and operation cost of treatment facilities to the aspects of microbial community to reveal the removal mechanism, GIS analysis in sourcing and the interaction relationship with rural residential environment improvement.
