中文摘要：

国家自然科学基金委员会“中国西部环境与生态科学研究计划”自2001年启动以来，有力地推动了西部区域环境演化、陆地生态过程和人类活动对环境的影响等方面的研究，积累了丰富的基础数据。国家自然科学基金委员会“中国西部环境与生态科学数据中心”承担“西部计划”项目数据产出的收集、管理、集成，并面向西部环境与生态科学的各个领域提供科学数据服务。“西部数据中心”的总体框架是以“西部计划”和地球系统科学发展的科学需求为导向，建成以数据共享、知识积累、合作交流和数据科学为主要内容的集成平台，为“西部计划”多学科的交叉研究和成果的综合集成及地球科学发展的长远目标服务。以共建共享的指导思想集成针对西部环境与生态现状与变化的基础背景数据、环境与生态观测数据、模型数据集、数据工具及数据文档；并以完全与开放的数据共享原则为用户提供推送式数据服务。目前，“西部数据中心”已完成了数据共享平台、知识积累平台与合作交流平台的开发和集成，初步形成了科学数据平台，整理并发布了大量的西部环境生态科学所需的关键数据集。

英文摘要：

The Environmental and Ecological Science Data Center for West China （WESTDC）, sponsorea by the National Natural Science Foundation of China （NSFC） , is aiming to collect, manage, integrate and disseminate environmental and ecological data for west China. The objective of the WESTDC is to build an integrated platform which has the functions of data sharing, knowledge accumulation, online scientific collaboration and data science development, and therefore provide a long-term service for multidisciplinary researches within the NSFCg “Environment and Ecological Science Program” and for the development of Earth System Science. Major data sets existing in WESTDC include remote sensing data, meteorological and hydrological data, background spatial data, scientific data of some inland river basins, data collected from individual projects, integrated data sets for west China, and customized data sets for specific hydrological or ecological models, along with data processing tools and data docu- ments. At present, WESTDC has completed the development of its integrated platform and has collected and released an amount of key ecological and environmental data sets for west China.
