| 摘 要： | 通过搜集从2003年到2016年与南水北调东线工程相关的1 405篇中文文献,借助LDA主题模型总共识别出13个有效主题,分别为“工程施工”“泵站运行优化”“水泵性能研究”“工程成本研究”“水环境模型”“河流水污染”“信息自动化”“湖泊富营养化”“水体污染物”“水泵结构计算”“水泵水力计算”“生态学”和“生态环境治理”,并对各主题的内容进行了分析,揭示出其内在的知识结构.然后使用了2个文献计量指标(主题占比和主题演变趋势)来描述南水北调东线工程的学术关注情况,发现“工程施工”为最热门主题,其次是“泵站运行优化”和“水泵性能研究”.而“水环境模型”和“湖泊富营养化”正逐渐成为研究热点.结果反映了学术界的关注情况,也为南水北调东线工程的后评价提供了决策依据.

| Abstract: | From 2003 to 2016, a total of 13 valid topics were identified by LDA(Latent Dirichlet Allocation)topic model through the collection of 1405 Chinese documents related to the South-to-North Water Transfer East Route Project.The topics include "engineering construction","pump station operation optimization", "water pump performance study", "engineering cost research","water environment model","river water pollution","information automation","lake eutrophication", "water pollutant","pump structure calculation","pump hydraulic calculation","ecology" and "ecological environment management".Two novel bibliometric indicators, including topic proportion and topic trend, were constructed to describe the academic concerns of the South-to-North Water Transfer East Route Project, ifnding that "engineering construction" is the most popular topic, followed by "pump station operation optimization" and "water pump performance study". However the "water environment model" and "lake eutrophication" are becoming a hot topic. The results reflect the attention of the academic circles and provide the basis for the post-evaluation of the South-to-North Water Transfer East Route Project. |
