基于文献计量分析法的中国生态脆弱性研究进展

以中国期刊全文数据库、中国优秀硕士学位论文全文数据库和中国博士学位论文全文数据库为文献检索来源,以生态脆弱性和GIS为检索词,对1980～2010年的文章进行了检索与分类统计,从数量、区域、内容、方法上对我国生态脆弱性研究进展进行分析。结果表明:期刊总论文259篇,其中核心期刊论文占44%;从1993年开始,相关期刊论文和硕博论文总体上呈逐渐上升趋势;2000年之后,我国生态脆弱性研究成为研究热点;从区域上分析,早期西南石灰岩山地生态脆弱区和华北平原生态脆弱区,北方半干旱-干旱生态脆弱区和西北半干旱生态脆弱区研究较多;后期南方丘陵生态脆弱区研究发展较快;从内容上分析,实证研究多于理论研究;从方法上分析,早期多以县域为数据单元,2000年之后开始出现栅格法地理信息系统技术,2005年起数量逐年增多。目前,从景观的角度探讨生态脆弱性的研究比较少,还没实现脆弱性的三维可视化表达。

Research Progress of Ecological Vulnerability Based on Metrological Analysis of Literatures in China

Based on Chinese Journal Full-text databases and full-text databases of Chinese doctoral and graduates’ theses,this paper analyzes China’s research progress of ecological vulnerability from the perspective of quantity,region,content and method.It retrieves and categorizes the papers published from 1980 to 2010 by taking ecological vulnerability and GIS as index words.Results show among the 259 journal papers,the core journal papers accounts for 44%.Since 1993,related journal papers and doctoral as well as graduates’ theses have been increasing.China’s research on ecological vulnerability has become a hot topic ever since 2000.From the regional analysis,in the early period more studies focused on ecologically vulnerable areas of Southwest’s limestone mountains,North China plateau,north semiarid & arid areas,and northwest semiarid areas,while in the later period more researches were seen in the ecologically vulnerable area of Southern hills.From the content analysis,there were more empirical studies than theoretical studies.From the method analysis,studies in the early period took the county as the data unit,and after 2000,the Grid GIS came into being.The number has gradually increased since 2005.Currently,studies that discuss ecological vulnerability from the perspective of landscape is seldom seen,and there are no 3D visualization on vulnerability.
