全球变化科学领域面临着体量巨大、增量迅速、种类繁多的观测数据和模拟数据的挑战，亟需新的研究思路和技术手段，实现数据的有效管理和分析，提高科学发现的效率。本文建议围绕科学数据、科研过程、学科交叉和国际国内合作4条主线开展全球变化科学领域的信息基础设施研究。该项研究需要理解该领域不同学科方向的科学数据，挖掘它们在概念、空间、时间、量纲、格式、编码等方面的联系，建立统一的数据概念模型；需要分析该领域不同学科方向的研究全过程，分析不同过程、阶段之间的共性，建立统一的研究过程模型；需要在“数据-方法-模型-系统-标准”5个层面开展学科之间的共享和集成，建立统一的数据逻辑模型和物理模型、方法库、模型库、集成系统和标准体系；需要发展国际国内的合作伙伴，践行开放共享的共建方案。本文最后概要介绍了这一理念的GlobalChangeOne研究项目的总体设计，以及在遥感科学、生态科学、大气科学、地球系统模式、计算地球系统科学等学科方向的具体研究进展。该项研究有助于促进全球变化科学领域多学科间的交叉研究，有助于提高该领域的科学研究工作的效率，有助于建成全球变化与可持续发展研究全球共享的一体化基础平台。

In the global change area, the volume of and the variety of accumulated observation and simulation data are expanding rapidly, creating challenges for the archiving, analyzing and sharing. To address these issues, this paper suggests four research strengths towards a research cyberinfrastructure in this area: scientific data, research process, interdisciplinary study, and national and international collaboration. Research on these aspects will lead to an integrated conceptual data model, an integrated research process model, a data processing module library, a data analysis service library, and a tree of standards and specifications. A research pilot project of GlobalChangeOne is highlighted to demonstrate the feasibility and the advantages of the proposed research roadmap. This research is very promising in facilitating the interdisciplinary studies and accelerating the scientific insights in the global change area, and in promoting the establishment of an integrated international platform for global change studies and sustainable development research.
