摘要 NSTL网络服务系统原文索取信息为研究对象,应用GIS的空间自相关性分析方法,对全国各省级行政区索取原文的文献量进行了空间分析,探讨这些区域索取文献的数量是否存在空间关联性,并以此为NSTL今后的资源采购和服务策略提供决策支持。 In this paper,studied the request information of full-text of NSTL network service system,applied the GIS spatial analysis method,analysed the provinces’ requests and judged the spatial correlation exist or not,and support the help for making the tactics of purchasing resource and serving of NSTL in the future.
