| 中文摘要: |
| 农村生活污水处理是农村人居环境整治的重点任务之一。本研究基于CiteSpace对2000—2020年Web of Science（WOS）数据库中农村生活污水研究领域的研究论文进行科学计量可视化分析。结果表明，在国际上，近5年农村生活污水领域研究论文累积发表186篇，数量呈持续增长趋势，正处于“成长期”，受到国内外学者的重视。基于关键词出现频率的共现与聚类分析可得，该领域研究进程中的高频关键词为“constructed wetland”“performance”“removal”“system”“nitrogen”，中国知网中文文章的高频词研究内容与其一致，主要热点话题为“nitrogen removal”“constructed wetland”“water quality”。对农村生活污水研究关键词从时区角度分析，并结合文章引用、关键词（包括）突发检测，发现农村生活污水未来研究将聚焦在利用人工湿地、土壤渗滤系统去除污染物，优化与研发农村生活污水处理工艺（植物、温度、组合工艺等），同时需加大污水沉积物的研究力度。本研究分析了农村生活污水处理领域可视化的进展和发展趋势，预测了该领域未来的研究方向，为推进农村环境污染治理提供了理论依据。 |

| Rural domestic sewage treatment is one of the vital tasks of rural environmental renovation.Herein,the research articles in the field of rural domestic sewage research from 2000 to 2020 in the Web of Science (WOS) were visualized in an analysis of scientometrics based on CiteSpace.Globally,186 research articles have been published in the field of rural domestic sewage in the past five years,and the number continues to increase.This field is in the"growth "stage,attracting attention from scholars globally.A co-occurrence and clustering analysis of the frequency of keywords was performed.High-frequency keywords in the research of rural domestic sewage treatment were found to be" constructed wetland" "performance" "removal" "system",and "nitrogen" .The content of high frequency words in Chinese articles from the Chinese National Knowledge Infrastructure was consistent with WOS.The main topics were"nitrogen removal" "constructed wetland",and "water quality" .The analysis of the time zone and the article references,and keywords with bursts suggested that the research on rural domestic sewage treatment focused on using constructed wetlands,multi-soil-layering to remove contaminants,optimization and development of technology (including plants,temperature,combination,etc.),and exploring the environmental problems which are going to happen with sewage sediment in the future.This paper provides a visualization of research progress and trends in rural domestic sewage,predicts the research content in the future,and provides a theoretical basis to promote rural environmental renovation. |
