中文摘要：

目前人们对地理信息科学基础理论的认识尚未达到完全统一。从地理学、测绘学和信息学理论视角凝炼出地理空间和时空基准、空间认知、地理信息传输过程、地理信息计算机表达、空间数据可视化与尺度、尺度分级规律以及地理数据不确定性等理论作为地理信息科学的基础理论，旨在引起国内学者对地理信息科学理论问题的探讨和思考，关注地理信息科学基础理论研究，推动地理信息科学的发展。

英文摘要：

At present the basic theories of geographic information science had not been reunified. In terms of geography, mapping and surveying, information theories and so on, some basic theories were summarized, including geographical space-geospatial and temporal reference, spatial cognition, geographical information transmission, geographical information expression in computer, spatial data visualization and dimension, scale clas-sification rules and the uncertainty of geographical data. The aims of that were to elicite the discussion and thinking on geographical information theories and to focuse researches of geographical information theories as well as to promote the development of geographical information science.
