长白山站2005-2020年土壤环境要素观测数据集

长白山站根据长白山自然保护区的植被分布，设有6个土壤观测场，涵盖5种典型生态系统，按照中国生态系统研究网络（Chinese Ecosystem Research Network，CERN）生态系统生物观测规范对其开展包括容重、机械组成、土壤养分全量、土壤矿质全量、微量元素全量、重金属全量以及阳离子交换量等的长期定位观测。本数据集收集和整理了2005-2020年土壤阳离子交换量（交换性钙离子、交换性镁离子、交换性钾离子、交换性钠离子、 交换性铝、交换性氢、阳离子交换量）、土壤养分（土壤有机质、全氮、全磷、全钾、速效氮(碱解氮)、有效磷、速效钾、缓效钾、水溶液提pH值）、矿质全量（SiO2、Fe2O3、MnO、TiO2、Al2O3、S、CaO、MgO、K2O、Na2O、P2O5、LOI）、硝态氮和铵态氮动态变化、机械组成和容重等实测数据，并进行了质量控制。该数据集可为森林土壤质量管理、生物地球化学研究和生态环境保护提供数据支撑。

Changbai Mountain Station has established 6 soil observation plots based on the vegetation distribution within the Changbai Mountain Nature Reserve, covering 5 typical ecosystems. Long-term in-situ observations were conducted in accordance with the ecosystem biological observation specifications of the Chinese Ecosystem Research Network (CERN), including measurements of bulk density, mechanical composition, total soil nutrients, total soil mineral elements, total trace elements, total heavy metals, and cation exchange capacity (CEC). This dataset collects and collates field-measured data from 2005 to 2020, covering soil cation exchange capacity-related indicators (exchangeable calcium ions, exchangeable magnesium ions, exchangeable potassium ions, exchangeable sodium ions, exchangeable aluminum, exchangeable hydrogen, and cation exchange capacity), soil nutrient indicators (soil organic matter, total nitrogen, total phosphorus, total potassium, available nitrogen (alkali-hydrolyzable nitrogen), available phosphorus, available potassium, slowly available potassium, and aqueous extract pH), total mineral elements (SiO₂, Fe₂O₃, MnO, TiO₂, Al₂O₃, S, CaO, MgO, K₂O, Na₂O, P₂O₅, LOI), dynamic changes of nitrate nitrogen and ammonium nitrogen, mechanical composition and bulk density. Quality control has been implemented for all the collected data. This dataset can provide data support for forest soil quality management, biogeochemical research, and ecological environmental protection.
