摘要
运用词频分析法,对清华同方《中国期刊全文数据库》1980-2008年农业领域的全部期刊进行分析,从草原荒漠化的研究领域、研究热点、主要研究单位等方面入手,分析我国温带草原荒漠化的研究现状。从而勾画出温带草原荒漠化研究的主要领域和发展趋势,向草业工作者展示了我国温带草原荒漠化持续不变的研究热点依然是草原沙化(退化)和草原畜牧业,气候变化、荒漠化治理、沙尘暴、超载过牧的研究逐渐成为新的研究热点。
By using frequency analysis of keywords, this paper analyzed all periodicals in agricultural field based on Tsinghua Tongfang＇s Chinese Journal Full-Text Database from 1980 to 2008. The research status of China＇s desertification study in temperate grassland was analyzed from research field, research focus and main research units to draw an outline of the main field and development tendency in China＇s temperate grassland desertification study. For grassland workers, the constant research focus still is the grassland desertification and grassland animal husbandry; climate change, desertification control, sandstorm and overloading and overgrazing have become new hot spots in this field.
