土壤学文献数量与其他学科一样,现正在迅速增长,根据英国《土壤肥料》文摘刊载文献统计,自20世纪50年代初至70年代初,文献量是每10年增长50％,而70年代初至80年代初的10年间却增长了一倍以上。同时由于多学科相互交叉及新的边缘学科不断发展,与土壤学相关的文献也大量增加。面对这一错综复杂的文献海洋,作为一个科研人员要浏览所有有关资料是不可能的,而且任何一个基层科研单位的图书馆其收藏文献的范围和数量是很有限的,这就需要一种查找资料的手段,这个手
The number of soil science literature, like that of other disciplines, is rapidly increasing. According to the literature published in the British Soil and Fertilizer Digest, the literature volume increased by 50% every 10 years from the early 1950s to the early 1970s, while in the early 1970s It more than doubled in the 10 years from the early 1980s. At the same time, due to the multidisciplinary interdisciplinary and new fringe disciplines, the literature related to soil science has also increased substantially. In the face of this intricate ocean of literature, it is impossible for a researcher to browse through all the relevant information, and the scope and number of collections of any library in a grass-roots scientific research unit are very limited. This requires a search The means of information, this hand
