| 摘 要： | 从发表的对地观测科学研究论文和专利文献入手，利用美国Thomson公司开发的Thomson数据分析工具（Thomson DataAnalysis—TDA），分析该研究领域的科研文献和专利文献变化情况，从而对对地观测技术的发展态势进行分析。在ISI Web of Knowledge平台检索SCIE和SSCI网络数据库2002—2007年相关论文共15829篇，对论文的国家和机构分布进行了详细分析，以关键词词频分析了对地观测技术研究的热点，得到微波遥感、定量遥感以及高光谱遥感是近年来的前沿领域，而土地利用和气候变化是应用热点。专利文献分析表明，对地观测专利文献呈现缓慢的增长趋势，全球定位系统专利文献数量较大、增长较快，而遥感、地理信息系统和全球定位系统专利文献分布国家和机构以及关键词词频具有较高的一致性，说明三者结合应用情况显著。

| Abstract: | From the research papers and patents on Earth observation, the development trends are analyzed by means of Thomson Data Analysis-TDA. For 15,829 papers in SCIE and SSCI databases between 2002 and 2007, the top 15 countries and top 10 organizations are analysed in detail. According to the frequency of topic words, the researches are focused on: maicrowave remote sensing, quantity research remote sensing(modelling) , hyperspectral remote sensing, land use and climate change . Based on DII, patents on remote sensing , geographic information system and global positioning system increase slightly between 2000 and 2006, and patents were owned by the United States, Korea, Japan, Germany, France, Australia and China. The top topic words of remote sensing, geographic information system and global positioning system are consistent, so the combination of three
research areas is very close. |
