中国湖泊沉积物理化生指标数据集（2021年）

该数据集包含了中国50个内陆水体表层沉积物和对应的表层水体物理化学生物信息，指标涵盖(i) 地理信息数据 , (ii) 气候数据, (iii) 水体理化指标 , (iv) 沉积物理化指标 , (v) 沉积物有机碳分解, (vi) 溶解性有机质多样性与组成和 (vii) 微生物多样性。数据采样分析时间为2021年，空间范围覆盖中国东北、内蒙、长江中下游和云贵高原湖区。数据格式为表格Excel文件，存放理化生数据及字段信息，数据记录共1650条。 "Lake_metadata.xlsx" file contains 50 samples of inland water bodies with variables including geographic data,climatic characteristics,water physiochemistry,sediment physiochemistry,sediment organic carbon decomposition,DOM traits and diversity,microbial diversityThis dataset contains surface sediments and corresponding physicochemical, chemical, and biological information of surface waters from 50 inland water bodies across China. The measured indicators cover seven categories: (i) geographic information data, (ii) climatic data, (iii) water physicochemical indicators, (iv) sediment physicochemical indicators, (v) sediment organic carbon decomposition, (vi) dissolved organic matter diversity and composition, and (vii) microbial diversity. Sampling and laboratory analyses were conducted in 2021, with the spatial scope covering lake regions in Northeast China, Inner Mongolia, the middle and lower reaches of the Yangtze River, and the Yunnan-Guizhou Plateau. The data are stored in tabular Excel files that contain physicochemical, biological datasets and field metadata, with a total of 1650 data records. The "Lake_metadata.xlsx" file includes 50 inland water body samples with variables such as geographic data, climatic characteristics, water physiochemistry, sediment physiochemistry, sediment organic carbon decomposition, DOM traits and diversity, and microbial diversity.
