中国亚东_格尔木地学断面GIS的初步建立

The Establishment of Yadong-Golmud Global Geoscience Transect GIS

在收集亚东_格尔木地学断面剖面地质图、地球物理解释图和综合解释图件等的基础上 ,首先针对断面的特点进行总体设计 ;然后进行主题、层和实体的划分及编码 ;最后利用GIS平台进行矢量化 ,完成空间数据库和属性数据库的建立 ,从而建立亚东_格尔木地学断面GIS的初步模型。

For the purpose of studying lithosphere structure of all continents in the world,the International_union Committee of Lithosphere,sponsored by different countries and organizations,set up global geoscience transect (GGT) project which includes more than 200 transects crossed major geological structures.In order to understand China continental lithosphere and its tectonic,structure,dynamics and material composition,the relationship among the different transects,and improve the knowledge about the earth's evolution and activity,the GGT GIS project was carried into practice and was founded by China Natural Science Committee.Based on the geological information,geophysical information,geographical and geophysical interpretation information,etc.,along the Yadong_Golmud transect,which is one of the eleven transects in China,the transect geographic information system was established.This paper mainly focuses on the establishment process of Yadong_Golmud transect under the Geo Trans GIS environment which was specially designed for global geoscience transect based on the TITAN GIS.It includes:designing the framework of the system,making standard codes for attribute and spatial database,building the Yadong_Golmud transect attribute and spatial database.In the end,the initial interpretation is given to show the importance and advantages of Yadong_Golmud global geoscience transect GIS.
