| 摘 要： | 网络学术信息虽存在于网络虚拟空间中,却与地理空间有密切关联.利用搜索引擎进行搜索后发现,网络学术信息的地理空间分布广泛,但易受学科差异影响.网络学术信息呈现北半球高南半球低,西方发达国家高、东方发展中国家中、非洲国家低的地理空间分布格局.美国呈"盆地式"地理空间分布格局,而中国则呈"阶梯式"地理空间分布格局.

| Abstract: | Though Internet is a virtual space,academic information on Internet is usually influenced by geospatial space.Using search engine,it can be found that academic information on Internet is widely distributed geographically around the globe,but vulnerable to impact of disciplinary differences.The geospatial distribution pattern of academic information on Internet is high in Northern Hemisphere,low in Southern Hemisphere,and high in the West,moderate in the developing countries in the East and low in the Africa... |
