现代地学研究离不开数据、模型、计算等资源,引入网格技术到地学领域,构建地学数据网格平台,是通过信息化技术支撑地学研究的有效方法和手段。本文分析了科研活动对地学数据网格的需求,并以人地系统科学数据网格为例,主要从网格资源层和网格服务层两个层面阐述了其建设思路。人地系统数据网格已经在中国科学院分布在全国的四家研究所进行了部署,其应用效果显示对改进地学研究方法、提高地学研究效率具有积极作用。
Modern geography research can not do without the data, model, calculation and other resources, the introduction of grid technology to the field of geology, building geo-data grid platform is through information technology to support geosciences effective methods and means. This paper analyzes the need of scientific research activities for geo-data grids. Taking the human-space system of scientific data grids as an example, this paper mainly elaborates its construction ideas from grid resources and grid service levels. Human-to-earth system data grids have been deployed at four institutes distributed throughout Chinese Academy of Sciences, and their application effects have shown a positive effect on improving the method of geoscience research and enhancing the efficiency of geosciences research.
