摘要
本文基于Web of Science数据库,对林学领域中GIS国际研究文献进行收集和数据清洗,分析年代文献增长、来源期刊分布,构建文献指数增长模型,研究作者关键词在不同时间段、不同高产国家、高被引文献中的演变趋势,采用社会网络分析软件Ucinet6.0绘制高频关键词的共现网络图,总结了林学领域中GIS的研究热点分布及其趋势。
On the basis of Web of Science, the paper collected data on forestry GIS international publications and cleans them. It makes a quantitative analysis from publications by year, exponential growth models, and publication journals. In addi- tion, it made an analysis of the evolution of author keywords from different time spans and high- production countries. Further- more＇, it analyzed the author keywords distribution of highly- cited literatures. Then it used the social network analysis software Ucinet6.0 to draw the co- occurrence network diagrams of high- frequency keywords. By co- analysis, it could conclude some hotspots distribution of GIS forestry international research.
