| 摘 要： | 利用CiteSpace软件对1995—2017年中国知网的"SCI来源期刊"、"EI来源期刊"、"核心期刊"以及"CSSCI来源期刊"数据库中有关干旱遥感监测研究的642篇文献进行可视化分析得到知识图谱。结果表明:国内经历了传统基于站点的干旱监测、小范围的干旱遥感监测试验到大范围干旱遥感监测及应用三个阶段;干旱遥感监测主要从"干旱监测"、"遥感监测"、"温度植被干旱指数"、"土壤湿度"、"地表温度"以及"归一化植被指数"等方向展开;王鹏新、张树誉、张强等是主要的发文作者;中国科学院、中国气象局、中国农业大学等是主要的发文机构。基于多源信息的干旱综合监测模型、大范围干旱监测评估、预警以及决策支持系统、干旱遥感监测技术在社会服务方面的应用以及加强国内学者与机构之间的交流合作是未来国内干旱监测研究几个重要方面。

| Abstract: | By using CiteSpace software with visual analysis for a knowledge graph, 642 papers were analyzed about research on drought monitoring using remote sensing technology from 1995 to2017 in the databases of "SCI Journals" , "EI Journals", "Core Journals" and "CSSCI Journals". The result shows China has experienced three stages on drought monitoring research, which are as follows: traditional site-based drought monitoring, small-scaled drought monitoring by remote sensing technology, and a wide-ranged drought monitoring and application using remote sensing technology. The drought monitoring by remote sensing technology were mainly conducted from the perspectives of "Drought Monitoring", “Monitoring using Remote Sensing technology”, “Temperature Vegetation Dryness Index (TVDI)”, “Soil Humidity”, “Land Surface Temperature” and “Normalized Difference Vegetation Index (NDVI)”. Wang Pengxin, Zhang Shuyu and Zhang Qiang are the main authors of the relevant papers. Chinese Academy of Sciences, China Meteorology Bureau and China Agricultural University are the main organizations where the authors come from. In the future, there are some important aspects about domestic drought monitoring research which include the multi-source based comprehensive drought monitoring model, the large-scale drought monitoring assessment, the early warning and decision support systems, the application of the drought monitoring using remote sensing technology in social services, and the reinforcement of the exchange and cooperation between domestic scholars and institutions. |
