摘要:

“数字地球”已经提出多年,是20世纪末期问世的定量化研究地球的一个新的战略方向。通过借鉴Google Earth,地质学界提出了建设One Geology和OGSEarth多层次多学科应用平台的概念。进一步提出构建基于化学元素在地壳的分布可视化,建立“化学地球”或者叫做“元素地球”(命名为Chemical Earth),能直观地揭示地壳中元素的分布,反映出不同大地构造单元元素时空分布、演化历史和矿床的物质背景。本项研究主要完成两个方面的内容:(1)研发一个基于ArcGIS Server二维和三维统一的“化学地球”软件平台,类似于谷歌地球(Google Earth)的数字地球软件平台,实现对地球化学数据和图形适时进行二维(平面)和三维(球面)联动;(2)建立地球化学数据库和提供图形化工具,实现对数据库进行多种方式的查询统计,如对不同尺度地球化学图的显示、图形与数据交互查询和采样信息查询等。

Abstract:

“Digital Earth” concept was initiated in 1990s; the “Google Earth” as the representative of the “Digital Earth” has become popular. A “Chemical Earth” or “Element Earth” software based on Internet for managing global geochemical data and visualizing global distribution of chemical elements in the Earths crust was developed. The software is focused on (1) building a unified “Chemical Earth” software platform in twodimensions and threedimensions based on ArcGIS Server, similar to Google Earth, which is a Digital Earth software platform to obtain the piece of available geochemical data and to demonstrate graphics timely in twodimensions and threedimensions; and (2) providing database and GUIbased tool to implement very conveniently the statistical database queries in various ways, such as displaying different scale geochemical maps, interactive queries of graphics and data, query of sampling information, etc.

Key words: GIS, geochemistry, Digital Earth, Chemical Earth
