Further,thekeywordfrequencycountedbyBibexcel,co鄄wordnetworksetupbyUcinetandNetdraw, co鄄word clustering analysis and multidimensional scaling analysis by SPSS, internal relations among high frequency keywordswere 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 relatedwith each other.
