摘要
采用文献计量方法,对Web of Science SCI-E数据库中的相关研究文献进行检索、统计和分析。结果表明,采用遥感技术开展崩滑流灾害研究的文献量呈指数型增长,说明遥感作为一种有效的研究手段获得了专家和学者的认可;美国、意大利、中国是应用遥感研究崩滑流灾害的主要国家;就研究中采用的影像类型而言,合成孔径雷达是当前采用最多的遥感影像类型;从研究主题看,地形形变监测,敏感性、危险性、风险性评估以及灾害的图像识别技术是这一领域的研究热点。
The paper uses bibliometric method to conduct retrieval, statistics and analysis of related document from SCI-E database of Web of Science. The result shows that the amount of document has been growing exponentially, which means remote sens- ing is recognized as an effective technology to study landslide; USA, Italy and China are the leading countries in this field; synthetic aperture radar （SAR） is used most frequently; monitoring of terrain deformation, assessment of landslide susceptibility, hazard and risk, and identification of disaster image are research hotpots of the area.
