发布时间：2018-09-04 11:36
【摘要】：近年来,国际上关于生态安全研究的文献大量涌现。随着全球变化和人类活动影响加剧,生态安全研究正发生着深刻变化,呈现出多目标、多层次、多学科交叉综合的复杂特点,研究主题日益丰富,但模糊性和争议性问题一直存在,对已有文献成果进行系统分析非常有必要。利用引文网络分析可视化工具CitespaceⅡ,通过绘制科学知识图谱,以定量与定性相结合的可视化文献综述研究方法,对各国学者发表的生态安全研究成果进行系统分析梳理,展示了研究主题的演进轨迹和发展趋势,总结了其发展变化的内在原因。研究表明:生态安全的研究主题可分为持续性和阶段性两类,主题演化轨迹符合Gartner光环曲线理论,人类文明发展阶段、国际政治经济格局、学科研究水平是决定生态安全研究阶段和主题演变的主要因素,该领域经历了问题提出与概念形成期、奠基拓展期、纵深发展期3个阶段,各阶段都有一些关键文献出现,这些引领学科发展的经典文献以自然科学研究为主;全球化、生物多样性、生态农业与农业集约化、恢复力、脆弱性是当前生态安全领域的研究热点;保障人类生存发展基本需要和人对环境变化的适应与响应将是21世纪生态安全研究的主要方向。
