2019年夏季达里湖不同深度细菌群落多样性数据集
A dataset of bacterial community diversity at different depths in Lake Dali in summer 2019
摘要
Abstract
As important components of regional ecosystems,lakes play a key role in regional climatic,hydrological cycles and ecological balance.The structure and composition of microbial communities directly affect the stability of ecosystems and the health of organisms,while also serving as key indicators of environmental pollution and the occurrence of diseases.Due to variations in physicochemical properties,water bodies at different depths often exhibit pronounced vertical differentiation in microbial community structure and function.Vertical distribution studies on bacterial communities in lakes on the Inner Mongolia Plateau,characterized by their unique geographical features,boasts both strong regional specificity and broad ecological significance.As a typical closed inland lake on the Inner Mongolia Plateau,Lake Dali provides an ideal natural laboratory for studying the structure of bacterial communities and its interactions with environmental factors,due to its unique geographical location and ecological environment.The dataset collect and collate information on the bacterial community composition of Dali Lake at different depths in summer 2019(derived from high-throughput sequencing and subjected to rigorous quality control and evaluation),together with key environmental parameters of the lake water,including water temperature,dissolved oxygen,conductivity,acidity and alkalinity,total nitrogen,total phosphorus,etc.(measured through laboratory experimental analyses),By revealing the vertical distribution patterns of bacterial communities,exploring the mechanisms by which environmental factors shape community structure,and assessing the potential ecological functions of key bacterial taxa,the dataset contributes to a deeper understanding of microbially driven processes in Plateau lake ecosystems.Moreover,it provides important scientific basis and technical support for coping with climate change,controlling eutrophication,mitigating pollution,and advancing biotechnological applications.The open sharing of this dataset will also furnish a valuable data resource for researchers in related fields.关键词
