【摘要】：在全球环境变化研究的背景下,土地利用变化已成为全球热点关注的话题。本文尝试利用21世纪大数据背景下丰富的资源,利用Cite SpaceⅢ软件特有"一图谱春秋,一览无余;一图胜万言,一目了然"的优势,分别用Web of Science(WoS)数据库收录的以"land use change(土地利用变化)"为主题的文献记录和来自中国知网(CNKI)数据库中以"土地利用变化"为主题词搜索的文献记录作为数据源,以定量分析方式结合Cite SpaceⅢ可视化图谱解读探索基于WoS数据库的土地利用变化的科研力量布局、学科知识基础,以及对比分析基于WoS和CNKI两个数据库的数据进行研究热点与前沿趋势的可视化分析后结果的异同。期待为我国土地利用相关政策的制定提供科学的参考依据,为我国在环境保护与可持续发展方面做出贡献。经过一系列的数据处理与分析得出以下结论:1.国内外在"土地利用变化(land use change)"领域的合作关系:首先发文量最多的作者是VerburgPH,发文量为58篇。作者合作网络中不具有合作关系的作者占一半以上。其次发文量最多的机构是中国科学院,发文量为744篇。中科院中心度值为0.32,在该领域机构合作网络中具有非常权威的地位。最后美国发文量最多,为2761篇,同时美国是该领域最具有学术权威性的国家,其中心度为0.44。2.土地利用变化研究的学科知识基础包括自然地理学领域、环境科学、生态、农业、遥感、水文、景观学等等的理论知识基础。该领域的学者应全面的掌握土地利用变化领域这几个方面的学科知识基础。3.国外在"土地利用变化(land use change)"领域的研究热点关键词主要有:"land use change(土地利用变化)" "land use(土地利用)" "climate change(气候变化)""impact(影响)""model(模型)""management(管理)""biodiversity(生物多样性)" "dynamics(驱动力)" "conservation(保护)" "forest(森林)" "vegetation(植被)" "deforestation(森林采伐)" "landscape(景观)""gis(地理信息系统)"以及"China(中国)"。结合关键词突现分布情况得知目前的研究热点主要是"生物燃料""生态系统服务""气候""温室气体排放"等。4.国外在"土地利用变化(land use change)"领域的研究前沿包括:首先是关于"生物燃料"方面的相关研究。其次是气候变化科学、气候变化与土地利用变化之间相互作用关系的探索。再次是关于"Land change science,LCS(土地变化科学)"的相关领域的研究。可持续性影响评估(sustainability impact assessment,SIA)是LCS的重要研究领域,定量的构建SIA评价指标体系是核心研究趋势。最后是关于世界森林对全球气候的影响方面的研究,热带、温带以及寒带地区的森林影响全球气候的机制研究等。5.我国"土地利用变化(land use change)"的研究热点与前沿趋势:首先土地利用变化领域的关键词分析得出国内研究热点包括:第一个阶段2002-2006年之间的土地利用变化研究主要集中在多时空以及区域层面的研究,理论应用于实践,开始运用3S技术建立各种土地利用/土地覆被变化模型。第二个阶段是2007-2015年,该阶段的主要研究热点包括LUCC生态环境效应研究,与前面不同的是在这个阶段加入了碳排放的研究以及驱动机制的研究。其次是我国土地利用变化(land use change)的研究前沿包括前沿研究话题包括"碳排放""生态系统服务价值" "SWAT模型""气候变化""情景模拟"等方面。6.国内外对比分析结果:我国目前对土地利用变化与生物燃料、土地利用变化温室气体排放之间的关系以及LCS等领域的研究较为缺乏。同时我国与其他国家在土地利用变化(land use change)领域的合作关系急需加强,通过合作提升国内在土地利用变化方面的科研水平是当务之急。
[Abstract]:Under the background of global environmental change research, land use change has become a hot topic in the world. This paper attempts to use the abundant resources in the background of large data in the 21st century, and use the unique advantages of Cite Space III software, which is "one map, spring and autumn, all at a glance; one picture is triumphant, all at a glance", to include them in the Web of Science (WoS) database. The research power of land use change based on WoS database was explored by quantitative analysis combined with Cite Space III visual Atlas interpretation, using "land use change" as the subject document record and "land use change" as the data source from CNKI database and "land use change" as the subject word search document record. Layout, subject knowledge base, and comparative analysis of data based on WoS and CNKI databases, the similarities and differences between the results of visual analysis of hot spots and frontier trends are expected to provide a scientific reference for the formulation of land use policies in China and contribute to environmental protection and sustainable development. A series of data processing and analysis have drawn the following conclusions: 1. Cooperation in the field of "land use change" at home and abroad: Verburg PH is the first author with the largest number of papers, and 58 papers are issued. More than half of the authors have no cooperative relationship in the cooperative network. Secondly, China Science has the largest number of papers. The center degree of CAS is 0.32, and it has a very authoritative position in the network of institutional cooperation in this field. Finally, the United States has the largest number of papers, which is 2761. At the same time, the United States is the most authoritative country in this field, with a center degree of 0.44.2. The scholars in this field should have a comprehensive grasp of the knowledge base of land use change in these aspects. 3. Foreign research hotspots in the field of land use change are mainly: "land use change" (land use change). Land use, climate change, impact, model, management, biodiversity, dynamics, conservation, vegetation, deforestation, landscape, GIS According to the distribution of key words, the current research hotspots are mainly "biofuels", "ecosystem services", "climate", "greenhouse gas emissions". 4. Foreign research frontiers in the field of "land use change" include: first, related research on "biofuels". Climate Change Science, Exploration of the Interaction between Climate Change and Land Use Change. Thirdly, research on the related fields of "Land Change Science, LCS". Sustainability Impact Assessment (SIA) is an important research field of LCS. Quantitative evaluation index system of SIA is constructed. Finally, it is about the impact of the world's forests on the global climate, tropical, temperate and cold zone forests on the global climate mechanism research. 5. China's "land use change" research hotspots and cutting-edge trends: first, land use change field keyword analysis obtained in the country Hotspots include: the first stage of land use change research between 2002 and 2006 mainly focused on Multi-temporal and regional level of research, theory applied to practice, began to use 3S technology to establish a variety of land use / land cover change models. The second stage is 2007-2015, the main research hotspots of this stage include LUCC. Second, the research frontiers of land use change in China include the frontier topics of carbon emissions, ecosystem services value, SWAT model, climate change and scenario simulation. 6. The comparative analysis results at home and abroad show that there is a lack of research on the relationship between land use change and biofuels, greenhouse gas emissions from land use change and LCS in China. It is a pressing matter of the moment to make use of the scientific research level of change.
