摘要
以中国知网学术期刊网络出版总库中2003—2012年的水资源学科核心期刊论文为基础,采用Bibexcel统计关键词频次,采用Ucinet和Netdraw绘制共词网络,运用SPSS进行共词聚类分析与多维尺度分析,研究高频关键词之间的内在联系,评述水资源学科的研究热点与研究现状。研究结果表明,水资源学科在研究过程中形成了水资源可持续利用、社会可持续、水资源系统和水资源管理四大类群体,并且四者之间具有较强的关联性。
Cluster analysis and multivariate statistics analysis for the co-words are performed taking into account the keywords in core journal papers on water resources issued in China Academic Journal Network Publishing Database （ CAJD） during 2003 to 2012. Further, the keyword frequency counted by Bibexcel, co-word network set up by Ucinet and Netdraw, co-word clustering analysis and multidimensional scaling analysis by SPSS, internal relations among high frequency keywords were studied. Additionally, the research focus and research status were analyzed. The results show that in the course of water resources science research four major communities of water resources research are developed： sustainable utilization, social sustainable development, water resources system and water resources management. Furthermore, these four major communities are greatly related with each other.
