分析学术研究与技术应用的发展,是我国水土保持生态技术技术辨识和评价的重要基础工作。近年来在学术研究与技术应用发展的分析工具中,文献计量统计方法和Citespace等可视化工具得到广泛应用。为分析我国水土保持生态技术进展,本文基于CNKI的中文研究文献(1985年1月至2017年3月)与专利数据(2002年1月至2017年2月),利用Citespace软件进行了初步研究。统计表明,约2002年后研究文献发表量、2010年后专利发明量迅速增加。Citespace的节点分析结果显示:1.该领域研究机构、研究团队和研究的兴趣指向偏于分散,目前尚未形成强的学科中心,机构间合作也较弱。2.水土流失严重的西部省区专利发明量远少于江苏、北京、山东、广东等东部省市。3.技术措施方面,主要的相对热点为植被恢复、生态护坡、保护性耕作等;研究区域方面是黄土高原、石漠化地区、干热河谷等;应用领域方面是高速公路、边坡、坡耕地等。4.研究热点主要在2002年文献量突增后的数年出现,但近5年来除石漠化外,尚无新的热点。建议下一步开展水土保持生态技术的技术辨识和评价工作,可聚焦于前述技术措施、重点区域和应用领域。
Analysis of the development of academic research and application of technology is an important foundation for the identification and evaluation of ecological technology for soil and water conservation in China. In recent years in the academic research and application of technology development tools, bibliometrics and Citespace and other visual tools have been widely used. In order to analyze the progress of eco-technology of soil and water conservation in China, this paper makes a preliminary study based on CNKI’s Chinese research literature (January 1985 to March 2017) and patent data (January 2002 to February 2017) using Citespace software. Statistics show that after about 2002 research literature published volume, after 2010, the amount of patented invention increased rapidly. The node analysis results of Citespace show that: 1. The research institutes, research teams and research interests in this field tend to be more fragmented. At present, there is not yet a strong center for disciplines and inter-agency cooperation is weak. 2. The quantity of inventions of inventions in the western provinces and autonomous regions with serious soil erosion is far less than those in eastern provinces and cities such as Jiangsu, Beijing, Shandong and Guangdong. 3. In terms of technical measures, the main relative hot spots are vegetation restoration, ecological slope protection and conservation tillage. The study area is the Loess Plateau, rocky desertification areas, dry-hot valleys, etc. The application areas are highways, slopes and slopes Cultivated land. 4. The hot spots of research mainly appeared in the years after the sudden increase of literature volume in 2002, but there was no new hot spot except rock desertification in the past five years. It is suggested that the next step should be to carry out technical identification and evaluation of soil and water conservation ecological technologies, focusing on the aforementioned technical measures, key areas and application areas.
