长江流域生物资源及生态环境研究进展

Bibliometrics research of documents on biological resources and ecological environment in the Yangtze River Basin of China

摘要:

以CNKI平台中的文献数据，利用文献计量学方法，对其文献的增长趋势及期刊分布进行分析，并基于作者和机构合作网络、关键词共现的聚类知识图谱及突变检测等方法，探究我国长江流域生物资源及生态环境主题的研究热点及其研究前沿。研究表明：研究文献总体上呈递增趋势，2016年开始呈现激增态势；作者、机构间的交流合作较少，作者间合作大部分局限在机构内部的研究者之间的合作，合作相对活跃的机构主要有长江科学院、长江流域水资源保护局及长江水利委员会等；其优势学科领域主要为环境科学、区域经济学、水利工程学、农业经济等。当前我国长江流域生物资源及生态环境的研究领域有5个方向：（1）开展长江经济带城市群生态环境评价与保护、城镇化与生态文明建设，以及绿色发展等研究；（2）开展长江三峡与三峡库区的生态环境监测与保护、森林资源养护、水土保持与流失、资源与生态补偿机制研究及其生态环境的可持续发展等研究；（3）开展长江流域自然保护区的生态环境保护与规划、生态保护红线及其生物资源养护与生物多样性保护等研究；（4）在长江大保护背景下，开展长江流域生态环境的保护与修复、流域综合治理，以及水生生物资源的合理开发利用的研究；（5）开展长江源区水电资源开发、水环境保护及其渔业生态环境保护等研究。为科学管理和保护长江流域的重要生物资源，提出建立基于科学设计的全流域生物资源和环境监测系统，建立全流域的生物资源及生态系统的生物数据模型，发展长江流域渔业资源养护与开发的风险评估决策系统，发展长江流域科学的渔业资源增殖放流技术体系，发展基于GIS的长江全流域的渔业资源与环境监测和管理决策信息服务系统等建议。

Abstract:

In this paper, we used the method of bibliometric analysis to review the documents related to the study on biological resources and ecological environment in the Yangtze River Basin of China and indexed CNKI database. We first created descriptive statistics of the number of articles published annually and the journal frequency distribution. Then, the methods of author, institution cooperation network and keyword based knowledge mapping and burst analysis were used to explore the hotspots and the recent frontiers.Descriptive statistics suggested that the number of research documents presented an increasing trend, and began to increase sharply in 2016. Authors and institutions have formed few frequent and stable cooperative relations.Most authors cooperation was limited to the researchers within the institution. The relatively active institutions cooperated among Yangtze River Scientific Research Institute, Yangtze River Water Resources Protection Bureau and Yangtze Water Resources Commission. Environmental science, regional economics, hydraulic engineering, agricultural economy are the dominant disciplines. Results of the burst analysis of the most recent document hotspots showed that the current research in biological resources and ecological environment in the Yangtze River Basin of China has four study frontiers:(1) carrying out research on ecological environment assessment and protection, urbanization and ecological civilization construction, and green development of urban agglomerations in Yangtze River Economic Zone; (2) research on ecological environment monitoring and protection, forest resources conservation, soil and water conservation and erosion, resources and ecological compensation mechanism and sustainable development of ecological environment in the Three Gorges and Three Gorges Reservoir areas; (3) Research on ecological environmental protection and planning, ecological red line, conservation of biological resources and biodiversity conservation in natural protection area of the Yangtze River Basin; (4) Under the background of the Yangtze River integrated protection program, carry out research on the protection and restoration of the aquatic biological resources, ecological environment, comprehensive management and the rational development and utilization of the aquatic biological resources; (5) Research on hydropower resources development, water environment protection and fishery eco-environment protection in the source area of Yangtze River.In order to manage and protect the important biological resources scientifically in the Yangtze River Basin,we suggest that we should establish scientific design monitoring system, and construct biological data models for fishery resources and ecosystems in the whole river basin, develop risk assessment and decision-making system for the conservation and development of fishery resources, and build scientific technological system for the proliferation and release, and develop GIS-based monitoring system for fishery resources and environment in the Yangtze River Basin.
