沙漠科学研究工作开展过程中涉及众多与地理位置紧密相关的试验区、采样点等信息。本文选择了Elsevier出版发行、SCI收录的生态环境类国际知名期刊《Journal of Arid Environments》(JAE)在2009年1月至2015年10月间出版的科技文献中以沙漠科学研究为主题的论文,采集其研究区或采样点的地理位置信息,同时结合著录者资料及作者关键词等相关信息,探索分析了沙漠科学研究在特定时间维度的演变轨迹与空间维度上的分布特征。结果显示,研究采样多选择在中低海拔地区,野外取样从沙漠边缘地带逐步向腹地区域深入,且随时间推移其范围呈扩张趋势。这一工作从文献计量学的角度为科研工作者宏观把握沙漠研究的区域选择变化趋势提供了参考。 |

Many sites location in different study areas have been involved during the study process of desert science. In this paper, all the papers published in the“Journal of Arid Environments”and concerning the study field of desert science during Jan 2009 - Oct. 2015 are selected as sample model. The location data from the papers involving sampling sites in different study areas are extracted. Based on the authors information and authors keywords, the spatial-temporal distribution characteristics in study area of desert science research field are explored. The results show that most of the study areas are selected in the low altitude region from edges to hinterland of deserts, and present an expanding trend as a function of year of study. The results provide an important reference for the desert scientific research felid to understand the development of study area selection from biblio-metrical perspective. |
