2005-2020年湖泊沉积物因子数据集

本数据产品是分别在湖北东湖站、湖南洞庭湖站、江西鄱阳湖站、江苏太湖站野外观测与质控，以及CERN水体分中心质量控制基础上，提交到国家生态科学数据中心。通过完善元数据，生产了本数据产品，即2016-2020年CERN水体生态系统湖泊站底质数据。本数据产品同时整理了湖北东湖站、湖南洞庭湖站、江西鄱阳湖站、江苏太湖站野外观测点介绍及观测指标获取方法与过程的关联文档。

This data product was submitted to the National Ecosystem Science Data Center after field observations and quality control conducted at Donghu Station (Hubei), Dongting Lake Station (Hunan), Poyang Lake Station (Jiangxi), and Taihu Lake Station (Jiangsu), as well as quality management by the Water Body Sub-Center of the China Ecosystem Research Network (CERN). By refining metadata, this data product—specifically the 2016–2020 CERN Aquatic Ecosystem Lake Station Substrate Data—was developed. Additionally, this data product compiles associated documents that introduce the four aforementioned field observation stations and elaborate on the acquisition methods and processes of the observation indicators.
