摘要

地学信息图谱所研究的地理空间规律和地理过程均具有一定的区域相似性, 故其在空间和时间上具有一定的区域特征，因此对地学信息图谱的研究均有空间和时间尺度方面的范畴。尺度是研究客体或过程的空间维和时间维。根据研究性质、研究对象的空间规模等方面的不同，地学信息图谱的空间尺度可分为大尺度、中尺度和小尺度；按研究的时间尺度不同，地学信息图谱的时间尺度可分为长时间尺度、中等尺度和短时间尺度。地学信息图谱的时空维是指地学信息图谱数据源的时空维或地学信息图谱可以表达的时空维，不同的时空维表达不同的特征和内容。

关键词： 时间尺度; 空间尺度; 时空维; 地学信息图谱

Abstract

Geo-Info-TUPU has the regional characters concerning the aspects of time and space for its research on the geography processes and geographical space rules have the regional similarity. So the study about Geo-Info-TUPU has the requirement for the spatial scale and temporal scale. Scale is the spatial and temporal attribution of the research-objects or research-process. According to the difference of the research characters,the spatial size of the research-objects and otherwise, the spatial size of the Geo-Info-TUPU can be divided into large scale,medium scale and small scale; according to the difference of the research time length, the temporal scale of the Geo-Info-TUPU can be divided into the long time scale,medium time scale and short time scale. The Spatial and Temporal Attribution of the Geo-Info-TUPU are the spatial-temporal attribution of the data sources or the spatial-temporal attribution of the Geo-Info-TUPU that can be expressed. Different spatial-temporal attribution can express different characters and contents about the research-objects.

Key words： Geo-Info-TUPU; Temporal scale; Spatial scale; Space-time attribution.
