2020年长江中游西凉湖和斧头湖野外调查采样数据

本数据集来自先导B项目“长江水系生物多样性丧失与生态修复策略”子课题“长江中下游湖泊生态系统稳定性和多样性研究”于2020年提取的湖北省西凉湖和斧头湖沉积岩芯，经过在湖泊沉积与环境国家重点实验室实验室的冻干、前处理和测试，得到采样点描述、样品含水量、粒度分布和质量磁化率，可用于长江中游浅水湖泊沉积记录的研究。

This dataset is derived from sediment cores collected from Liangzi Lake and Futou Lake in Hubei Province in 2020, which were obtained under the sub-project "Research on Ecosystem Stability and Diversity of Lakes in the Middle and Lower Reaches of the Yangtze River" of Pilot Project B "Biodiversity Loss and Ecological Restoration Strategies in the Yangtze River Watershed". After undergoing freeze-drying, pretreatment and testing at the State Key Laboratory of Lake Sedimentation and Environment, the dataset includes sampling site descriptions, sample moisture content, particle size distribution and mass magnetic susceptibility, and can be used for research on sedimentary records of shallow lakes in the middle reaches of the Yangtze River.
