1992~2019年我国水质评价研究进展与热点综述：基于CiteSpace的知识图谱分析

Review on the Research Progress and Hot Spots of Water Quality Assessment in China from 1992 to 2019: Analysis of Knowledge Graph Based on CiteSpace

摘要: 随着我国社会经济的快速发展，水资源污染的问题日趋凸显，水安全问题逐渐受到人们的关注和重视。在水安全问题的研究中，城市供水安全一直是研究的核心问题之一，而水质安全又是城市供水安全建设的重要影响因素，对水质安全如何做出科学合理的评价并对水安全程度进行表征是水质安全领域研究中的首要问题。因此，开展水质安全评价是一个既基础又重要的工作。同时，水质安全评价也是开展流域水资源保护工作的重要前提，对其开展文献综述研究能够为水质安全评价研究提供参考。本研究利用CiteSpace软件进行我国水质评价核心文献的知识图谱可视化分析，绘制发文量统计、关键词分析和热点词分析图。研究发现：1992~2019年间，我国水质评价研究的发文量主要分为“稳定波动–迅速增加–剧烈波动”3个主要阶段；关键词分为“领域–对象–方法”3个主要类型；热点词主要有环境质量评价、人工神经网络、因子分析等。该研究将为我国流域水资源的开发、利用和保护以及水质综合评价提供一种有效的评价方法和数据支撑。

Abstract: With the rapid development of my country’s social economy, the problem of water resource pollu-tion is becoming more and more prominent, and the issue of water security has gradually attracted people’s attention and attention. In the study of water safety issues, urban water supply safety has always been one of the core issues of the study, and water quality safety is an important influencing factor for the construction of urban water supply safety. How to make a scientific and reasonable evaluation of water quality safety and carry out water safety degree? Characterization is the primary issue in the field of water quality safety research. Therefore, carrying out water quality safety assessment is a basic and important task. At the same time, water quality safety assessment is also an important prerequisite for carrying out water resources protection in river basins. Literature review studies on them can provide a reference for water quality safety assessment re-search. In this study, CiteSpace software was used to visually analyze the knowledge graph of the core documents of water quality evaluation in my country, and to draw statistics of the amount of text, keyword analysis, and hot word analysis. The study found that: from 1992 to 2019, the volume of published water quality assessment studies in China was mainly divided into three main stages: “stable fluctuation-rapid increase-severe fluctuation”; keywords were divided into 3 main types of “domain-object-method”; Hot words mainly include environmental quality assessment, artificial neural network, factor analysis and so on. The research will provide an effective evaluation method and data support for the development, utilization and protection of water resources in my country’s river basin and comprehensive evaluation of water quality.
