当前科技文献“爆炸性”增长,学科间广泛交叉、相互渗透,因而文献工作的重要性日益被人们所公认。对地理科学来说,很久以来就认为是综合性科学、它的研究对象之广,可伸展到自然界和人类社会以及自然与人类赖以存在的地理环境空间。所以,地理学的文献工作较其他学科有更大的难度。正因为如此,建立地理学二次文献系统就更加必要。特别是把该系统与相关的地学联合建立情报网络,既是促进地理科学研究和地理情报工作发展的极其必要的措施,又会加快地理科学情报工作前进的步伐。 地理科技情报二次文献系统主要有以下几种功能:存储管理功能、检索功能和报道 At present, the explosive growth of science and technology literature and the wide interdisciplinary and interpenetrating interdisciplinary literature have made the importance of literature work increasingly recognized. For geography, science has long been considered a comprehensive science, its object of study is wide, it can be extended to nature and human society, and the natural and human beings rely on the geographical space. Therefore, the literature of geography has more difficulty than other disciplines. Because of this, it is even more necessary to establish a secondary literature system of geography. In particular, the joint establishment of an intelligence network with the relevant geosciences is not only an extremely necessary measure to promote the development of geosciences research and geo-intelligence work, but also speed up the progress of geoinformatics intelligence work. Geographic information science and technology secondary literature system has the following functions: storage management functions, retrieval and reporting
