Soil Chemical Properties in Zeya Nature Reserves of Russian Far East

This dataset contains analytical data describing the chemical and optical properties of soil organic matter (SOM) and water-soluble soil organic matter (WSOM) collected from boreal forest soils in the Zeya State Nature Reserve, Russian Far East. Soil samples were obtained from multiple vegetation zones along an elevation gradient, including montane forest, subalpine, and alpine tundra environments, as well as sites with and without wildfire disturbance history.
The dataset includes measurements of soil physicochemical properties, elemental composition, molecular composition, and optical characteristics. Specifically, the data include elemental carbon and nitrogen contents, soil moisture content, bulk density, ignition loss, and pH, as well as molecular composition data obtained using tetramethylammonium hydroxide pyrolysis–gas chromatography–mass spectrometry (TMAH-Py-GC/MS). In addition, water-soluble organic matter data include dissolved organic carbon concentrations, ultraviolet–visible absorbance spectra, and excitation–emission matrix fluorescence spectra.
The dataset contains both raw and processed analytical outputs used to characterize SOM and WSOM across different vegetation types and environmental conditions. These data provide reference information on soil organic matter composition in boreal forest ecosystems and may be reused for comparative studies, environmental assessments, and investigations of soil carbon dynamics and wildfire-affected environments.

本数据集收录了俄罗斯远东地区泽亚国家自然保护区内寒温带森林土壤中采集的土壤有机质（Soil Organic Matter, SOM）与水溶性土壤有机质（Water-Soluble Soil Organic Matter, WSOM）的化学及光学特性分析数据。土壤样品采自沿海拔梯度分布的多个植被带，包括山地森林、亚高山带与高山冻原环境，同时涵盖了存在野火扰动历史与无野火扰动历史的样地。
本数据集包含土壤理化性质、元素组成、分子组成及光学特性的测定数据。具体而言，数据集涵盖了元素碳、氮含量，土壤含水量、容重、烧失量及pH值等指标，同时包含采用四甲基氢氧化铵热解-气相色谱-质谱联用法（Tetramethylammonium Hydroxide Pyrolysis-Gas Chromatography-Mass Spectrometry, TMAH-Py-GC/MS）获得的分子组成数据。此外，水溶性土壤有机质相关数据包括溶解性有机碳浓度、紫外-可见吸收光谱及激发-发射矩阵荧光光谱。
本数据集包含用于表征不同植被类型与环境条件下土壤有机质及水溶性土壤有机质的原始分析结果与经预处理的分析数据。
这些数据可为寒温带森林生态系统的土壤有机质组成提供参考信息，可被重复用于比较研究、环境评估以及土壤碳动态与受野火影响环境的相关调查研究。
