中文摘要:

      长期以来我国盐湖科学数据存在分散、局限于单学科领域、多元异构、数据共享性差等问题,不利于引导盐湖科学领域的重大和协同产出。为进一步促进盐湖科学数据的信息化,更好地服务于盐湖科学研究,在国家科技部基础性工作专项、中科院百人计划等项目的支持下,课题组从分析盐湖科学数据特点、数据现状和用户需求入手,对多学科多源数据整合、数据质量控制、软件协同、各主题数据库结构和逻辑关系、数据挖掘等关键性问题进行研究,充分利用GIS空间管理信息系统的优势,完成了盐湖资源与环境数据平台的设计及功能开发。该平台实现了对历史与现在的、分散与多元的盐湖科学数据的有效整合。通过将盐湖领域科学数据资源聚集、挖掘和融合,以期达到用数据和信息的杠杆引导盐湖科学向符合信息时代特征方向发展,建立以数据驱动的科研创新范式,为我国盐湖科研创新奠定坚实的数据基础。

英文摘要:

      Historically,China’s scientific data of salt lakes have the characteristics of decentralization,limited to single-disciplinary fields,multi-heterogeneous,and poor data sharing,which is not conducive to guiding the major output of the salt lake science field.In order to promote the level of informationization of the current scientific data of salt lakes,and to provide better data services for the scientific research of salt lakes,sponsored by the project of the Ministry of Science and Technology and CAS(Chinese Academy of Sciense),the analysis of Salt lake scientific data characteristics,data status and data user needs,multi-disciplinary multi-source data integration,data quality control,software collaboration,key database structure and logical relationship,data mining and other studies were conducted by Data science team of ISL(Qinghai Institute of Salt lakes,CAS)since 2014,and the advantages of GIS(geographical management information system )were fully utilized to set up the functional salt lake resources and environmental data platform.This platform enables the effective integration of historical and current,decentralized and diverse salt lake scientific data.Through the aggregation,mining and integration of the scientific data resources of the whole salt lake resource system,we hope to use the lever of data and information to inspire the progress of salt lake science and to create a new paradigm of data-driven innovation ,and to lay a solid data foundation for scientific research and innovation in China′s salt lakes study.
