摘要
生态脆弱区不仅是中国重要的生态屏障,更是脱贫攻坚、全面建成小康社会的重要区域.以中国知网期刊全文数据库(CNKI)为数据源,采用CiteSpaceⅤ可视化对1989年以来我国生态脆弱区研究状况进行分析.结果显示,近三十年生态脆弱区研究逐渐成为学术热点,形成缓慢增长、迅速发展和成熟发展3个阶段;以实证研究为主,理论研究相对较少,近年来有理论探讨和综合化研究增多的趋势;研究区域以北方和西部地区为主,内蒙古、陕西、甘肃、贵州、云南是实证研究的主要区域;研究方法注重多学科融合,使用遥感影像数据和GIS工具进行研究的文献越来越多.通过生态脆弱区研究关键词共现图谱,结合文献阅读,提取出生态脆弱区研究的5大热点,并对土地利用/覆被变化、气候变化及其影响、生态脆弱性评价、人地关系与可持续发展、生态修复5大热点的具体研究内容、方法及逻辑框架等进行阐述.最后从完善评价指标与模型、拓宽研究时空尺度、关注人为因素的影响、关注农户生计、探究生态修复的最佳方式等方面提出展望,以期为生态脆弱区研究的进一步深入提供参考借鉴.
Ecologically vulnerable area is not only an important ecological barrier in China,but also an important area to overcome poverty and build a moderately prosperous society in all respects.Therefore,based on the database of China Knowledge Network(CNKI),this study analyzes the research status of ecologically vulnerable area in China since 1989 from the point of view of bibliometrics by using Citespace information visualization software.The results show that,in the past three decades,the study of ecologically vulnerable area has gradually become a hot topic in academic circles,and formed three stages of slow growth,rapid development and mature development.Empirical research is the main part,theoretical research is relatively less,and there is a trend of increasing theoretical research and comprehensive research in recent years.The research area is mainly in the western and northern regions,and Inner Mongolia,Shaanxi,Gansu,Guizhou and Yunnan are the main areas of empirical research.Research methods focus on multi-disciplinary integration,more and more literatures use remote sensing image data and GIS tools for research.Through the cluster knowledge map of ecologically vulnerable area in china based on keywords,combined with literature reading,five hotspots in the study of ecologically vulnerable area are extracted.Including land use and land cover change,climate change and its effects,ecological vulnerability assessment,man-land relationship and sustainable development,ecological restoration.Finally,in order to provide reference for the future research,this study puts forward five prospects.Including improve the evaluation index and model,broaden the space-time scale of research,pay attention to the influence of human factors,pay attention to the livelihood of farmers,explore the best way of ecological remediation.
