基于CiteSpace的我国水资源利用效率研究知识图谱分析

基于2000—2020年中国知网上CSSCI、EI数据库收录的有关水资源利用效率研究的文献，利用CiteSpace软件绘制国内水资源利用效率研究的知识图谱，分析了我国水资源利用效率研究的时间、作者、机构分布情况以及研究热点和研究趋势。研究结果显示:水资源利用效率的研究主体间呈现合作不够、较为分散的特点；研究关键词可聚类为水权交易与水权制度、水足迹、水资源短缺、农业水价、水资源承载力、产业结构等；水资源管理、水足迹、影响因素、工业用水、长江经济带、水资源利用效率、绿色水资源效率、长江流域及长江经济带的绿色发展将会是未来的研究热点。

Knowledge graph of researches on utilization efficiency of water resources in China based on CiteSpace

Based on the literatures on utilization efficiency of water resource collected by CSSCI and EI databases on CNKI from 2000 to 2020, the knowledge graph of researches on utilization efficiency of water resources in China is drawn by using the CiteSpace software, and the distribution of time, authors, institutions, research hotspots and trends are analyzed. The results show that there is not enough cooperation among the main body of the researches on utilization efficiency of water resources. The key words can be grouped into water right trading and water right system, water footprint, water shortage, agricultural water price, carrying capacity of water resources, industrial structure, etc. The research hotspots in the future include water resource management, water footprint, influencing factors, industrial water use, Yangtze River Economic Belt, utilization efficiency of water resources, efficiency of green water resources, green development of the Yangtze River Basin and the Yangtze River Economic Belt.
