Abstract: | 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 addition,it made an analysis of the evolution of author keywords from different time spans and high-production countries.Furthermore,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. |
