摘要
自三峡工程论证以来,三峡库区水环境研究就已成为热点问题。为探究其多年的研究成果,基于2000~2020年WOS和CNKI数据库中三峡库区水环境相关研究的文献样本数据,利用文献可视化分析软件CiteSpace,对年度发文量、学科分布、关键词共现及突现词探测等进行文献计量与内容分析。结果表明:(1)2000~2020年,关于三峡库区水环境研究的论文总体呈现逐年稳定上升的趋势,研究涉及多学科领域知识;(2)香溪河、洞庭湖、时空变化、环境因子、沉积物、澎溪河是当前研究的前沿问题;(3)消落带、富营养化、香溪河库湾、澎溪河、水华、沉积物、浮游植物、重金属、洞庭湖、水质、生物群落、生物群落、动力学、氮、磷、生态系统、环境因子等是该领域的热点内容,主要体现在三峡库区水体富营养化研究、三峡库区消落带研究、三峡工程对长江中下游影响研究、三峡库区面源污染问题研究、三峡库区沉积物研究等5个方面。基于研究结果,指出了现有研究存在的一些不足,并提出了三峡库区水环境的研究展望。
Since the demonstration of the Three Gorges Project,the research on its water environment has become hot issues.Sample data on water environment of the Three Gorges Reservoir Area in WOS and CNKI databases from 2000 to 2020 was visualized by using CiteSpace.In specific,the annual literature quantity,discipline distribution,keyword co-occurrence and emergent word detection were analyzed.The results indicate that from 2000 to 2020,the related researches involving multi-disciplinary knowledge have increased steadily year by year;Xiangxi River,Dongting Lake,temporal and spatial changes,environmental factors,sediments and Pengxi River are the frontier issues currently;water-level fluctuation zone,eutrophication,Xiangxi River reservoir bay,Pengxi River,water bloom,sediment,phytoplankton,heavy metals,Dongting Lake,water quality,biological community,biome,dynamics,nitrogen,phosphorus,ecosystem and environmental factors are the hot topics in this field,mainly are manifested in water eutrophication,the fluctuating zone,non-point source pollution and sediment in the Three Gorges Reservoir area,and the impact of the Three Gorges Project on the middle and lower reaches of the Yangtze River.Furthermore,some shortcomings of the existing research are pointed out,and the research prospect of the water environment of the Three Gorges Reservoir area is proposed.
