摘　　要：生态系统长期观测(Long Term Observation for Ecosystem,简称EcoLTO)数据产品是在“统一监测”、“统一数据管理”过程中建成的规范化EcoLTO数据库基础上,通过进一步处理加工、分析挖掘后形成的更高质量的数据形态。数据产品能更好体现EcoLTO数据长期性、多样性、灵活性等特征。国家生态科学数据中心(NESDC)在将EcoLTO数据产品化过程中,需要研制EcoLTO数据产品规范,以便对“统一数据产品”的生产、质量控制、存储管理、开放共享发挥指导作用,进而支撑面向科研人员提供更高质量的产品共享服务。本文介绍了EcoLTO数据产品规范研制过程、产品规范的组成内容、产品规范在实践中的使用方法,并给出了产品规范在NESDC数据共享服务平台中的应用案例。本文可为数据产品的生产者、管理者及使用者理解EcoLTO数据产品规范提供参考,有助于产品规范的推广和应用。The standardized Long-term Observation for Ecosystem(EcoLTO)database is established based on centralized monitoring and data management.A data product is a form of EcoLTO data with higher quality and is produced by further processing and mining to the standardized EcoLTO database.It could reflect data’s characteristics such as long-term,variety and flexibility much better.Data Center of National Ecology Science(NESDC)needs to develop an EcoLTO data product specification(EcoLTO-DPS)during formation of data products from EcoLTO database to guide the product’s producing,quality control,storage management and open access.This will further support the higher-quality products sharing for scientific researchers.This paper introduced EcoLTO-DPS’s development procedures,package components and methods to use EcoLTO-DPS,and also it gave an example applied in data portal of NESDC.The paper could provide a reference for data products’producers,managers and users to understand EcoLTO-DPS and help to promote and use EcoLTO-DPS.
