生态修复是生态文明建设的重要内容。开展生态修复是解决生态环境问题的一项重要举措，关系到国家长治久安。相关研究工作为生态修复工程的开展提供有力支撑。分析中国生态修复研究发展进程，研究中国在当前和未来的生态修复工作重点，可以为未来相关研究的开展提供科学的参考意见。本研究以从中国科学引文数据库中筛选出的 1000 篇文献、以及从 Science Citation Index Expanded 数据库和 Social Sciences Citation Index 数据库筛选出的147 篇文献为研究对象，采用文献计量学，从文献年产出量、研究主题、研究对象、研究所在地、研究方向、研究机构、文献所在期刊和各层次（国家、机构和作者）合作发展趋势等方面，对中国生态修复研究发展进程进行了全面、系统地定量分析。同时，本研究以 2013 年至 2017 年《中国环境报》中的 251篇生态修复新闻报道为研究对象，从生态修复新闻报道的数量变化趋势、版面分布、来源、议题内容、提及的区域等方面，分析了中国在当前和未来的生态修复工作重点。研究结果表明中国生态修复研究自 1998 年以后呈现快速增长趋势。超过75%的研究侧重于：理论、技术、措施的运用与适用性评价，以及生态修复工程的监测和评估。针对政策、法律、管理和补偿机制的研究仍有不足，有待深入和完善。生态修复研究的对象主要为：江河湖泊、矿区、退化土地、湿地、黄土高原、森林、流域、边坡、水利水电工程、草地、山地、喀斯特地貌区、农业区和城市生态系统，这些研究对象占比超过 70%。但水体生态修复研究目标亟待从改善水质转变为对水生态系统进行修复。为修复退化土地起支撑作用的相关理论与技术的研究与创新也需不断推进。水利水电工程对生态环境造成的负面影响不容小觑。因此，针对工程废弃地的修复、水库消落带的修复、工程所在地的生物多样性保护已引起科研人员的重视。具有生态学、环境科学、农学、林学、植物学、工程学、地质学、水资源学或环境工程背景的科研人员是该领域的主要研究力量。中国科学院、北京林业大学、北京师范大学和西北农林科技大学是该领域的主要研究力量。作者间合作越来越密切，机构间合作合作模式主要为双边合作模式，但我国与其他国家的国际合作有待加强。国家间通过国际合作能实现优势互补，进而提升研究能力，最终取得突破性进展。当前，全国各地广泛开展生态修复工作，生态修复工作重点为对城市生态系统、乡村生态系统和江河湖泊进行修复。针对湿地的修复将成为生态修复工作的重点。

Ecological rehabilitation is an important part of ecological civilization construction. Carrying out ecological rehabilitation project is an essential measure to solve eco-environmental problems, and safeguard ecological security of China. Correlative research provides strong support for the development of ecological rehabilitation project. It can help the ecological rehabilitation research develop much better in the future by analysing the development tendency of ecological rehabilitation research in China, and studying current and future ecological rehabilitation work priorities of China.To analyse the development tendency of ecological rehabilitation research in China, we systematically and quantitatively analysed 1000 articles published in the Chinese Science Citation Database and 147 articles retrieved from the Science Citation Index Expanded database and the Social Sciences Citation Index database by using a bibliometric analysis approach. We focused on article output characteristics, research topics, research objects, study areas, research directions, major research institutions, journals publishing the ecological rehabilitation research, and the trends of academic collaboration among countries, institutions and authors. At the same time, to study current and future ecological rehabilitation work priorities of China, we analysed 251 newspaper articles about ecological rehabilitation published in the China Environment News from 2013 to 2017 by using a content analysis approach. The output characteristics of the newspaper articles, news pages, news sources, distribution of the newspaper article outputs among report topics, and the geographic location reported in the newspaper articles were discussed.The results show that annual article output has increased sharply after 1998. More than 75% of the research topics focus on developing theories, technologies and approaches, as well as evaluating their applicability; monitoring and assessing ecological rehabilitation projects. The research topics involve policies, laws, and the mechanisms of management and compensation, still to be strengthened. The research objects focus on rivers and lakes, mining areas, land degradation, wetlands, the Loess Plateau, forests, watersheds, slopes, water conservancy and hydropower projects, grasslands, mountainous regions, Karst area, agricultural region, and urban ecosystems. These research objects accounted for more than 70%. However, the objective of ecological rehabilitation of water bodies needs to be changed from improving water quality to restoring water ecosystems. The research and innovation of relevant theories and technologies that support the rehabilitation of degraded land also need to be continuously promoted. The negative impact of water conservancy and hydropower projects on eco-environment cannot be underestimated. Therefore, researchers have paid great attention to restore the project wastelands and the water-level-fluctuating zones, and protect biodiversity in the project sites.Researchers with backgrounds in ecology, environmental sciences, agriculture, forestry, plant sciences, engineering, geology, water resources, or environmental engineering are the main research forces. The Chinese Academy of Sciences, Beijing Forestry University, Beijing Normal University and Northwest A&F University are the main research forces. Academic collaborations of authors exhibit an increasing trend. The collaboration mode of institutions is mainly bilateral collaboration. International collaboration between China and other countries needs to be strengthened in the future so as to learn from and help each other, to make up each other's deficiencies. At present, ecological rehabilitation project is widely carried out throughout the country, and ecological rehabilitation project focuses on urban ecosystems, rural ecosystems, rivers and lakes. The protection and rehabilitation of natural wetlands will become the key issues in the future.
