中国土地利用/覆被变化研究综述 ———基于文献计量学的可视化分析

Review of Land Use/Cover Change Research in China— Visual Analysis based on Bibliometrics

20世纪中期以来, 全球人口剧增, 人类活动侵占了大量的自然空间, 造成剧烈的土地利用/覆被变化, 引发了一系列气候变化、环境污染、资源短缺等生态安全问题, 对全球可持续发展造成严峻挑战。中国是全球国土面积最大、人口最多的发展中国家, 土地利用/覆被的变化更为明显。因此, 开展中国土地利用/覆被变化领域的综述分析, 在应对全球变化、修复生态破坏、缓解人地矛盾等方面具有重要意义。本文基于Web of Science数据库中2012—2022年中国土地利用/覆被变化领域的文献, 利用Bibliometrix和Biblioshiny软件包, 分析了中国土地利用/覆被变化领域的研究现状、特点、区域差异及演变规律。研究表明: (1) 中国土地利用/覆被变化领域论文的年发表量呈 稳步上升趋势。但是年均被引量呈现波动下降的趋势; (2) 2012—2022年间共有73157位作者在中国土地利用/覆被变化领域发表了文章, 其中张镱锂、刘彦随和李秀彬发文量位列前三; (3) 全球153个国家或地区在中国土地利用/覆被变化领域有文献产出, 产出量排名前三分别是中国、美国和德国。其中, 中国和美国在中国土地利用/覆被变化领域的文献产出在国际合作中发挥了重要作用。 (4) 中国土地利用/覆被变化研究的关键词可以分为三类: 第一类侧重于中国土地利用/覆被变化驱动因子/因素的研究; 第二类重点关注中国土地利用/覆被变化研究的模型与技术方法; 第三类强调政策及政府的管理的作用; (5) 2012—2022年的十年间, 中国土地利用/覆被变化领域主题的变化不大, 主要围绕着气候变化和管理开展相关研究工作。

Since the mid-20th century, the global population has increased dramatically, and human activities have encroached on a large number of natural spaces, resulting in drastic land use/cover changes. A series of ecological security problems took place as a result, such as climate change, environmental pollution, and resource shortage, posing severe challenges to global sustainable development. As the largest and the most populous developing country in the world, China’s land use/cover change is more prominent compared to that of other countries. Therefore, the comprehensive analysis of land use/cover change in China is of great significance in dealing with global change, repairing ecological damage, and alleviating the contradiction between man and land. Based on the literature of land use/cover change in China from 2012 to 2022 in the Web of Science database, this paper analyzes the research status, characteristics, regional differences, and evolution law of land use/cover change in China by using Bibliometrix and Biblioshiny software packages. The results show that: (1) The annual number of papers published in the field of land use/cover change in China is steadily increasing. However, the average annual citation amount fluctuates but shows a general downward trend; (2) From 2012 to 2022, a total of 73, 157 authors published articles in the field of land use/cover change in China, among whom Zhang Yili, Liu Yansui, and Li Xiubin ranked the top three; (3) 153 countries or regions in the world have literature output in the field of land use/cover change in China, and the top three output countries are China, the United States and Germany. Among research, papers from China and the United States has played an important role in international cooperation in the field of land use/cover change in China; (4) The key words of land use/cover change research in China can be divided into three categories: the first category focuses on the research of driving factors/factors of land use/ cover change in China; The second category focuses on the models and technical methods of land use/cover change research in China; The third category emphasizes the role of policies and government management; (5) During the ten years from 2012 to 2022, the theme of land use/cover change in China changed little, mainly focusing on climate change and management.
