青藏高原森林结构-林龄数据集（1993-2016）

基于文献搜集与数据库整合方法，构建了青藏高原森林生态系统结构-林龄数据集。该数据集包含林龄、地上/地下生物量、地理位置、森林类型等要素。该数据集的构建有助于深入理解该区域森林生物量与林龄的关系及其分布特征。数据来源于118篇文献与282个样地，经过剔除重复与异常值，并依据优势物种或植被类型划分为针叶林、阔叶林和混交林。经过认真的数据整合与清洗，保障了数据的可信度与准确性，数据质量优良。该数据集可为青藏高原森林生态系统研究提供基础数据支持，如验证生态系统模型碳循环过程的模拟。

A dataset of forest ecosystem structure and stand age on the Qinghai-Tibet Plateau was constructed through literature collection and database integration. This dataset covers components including stand age, aboveground/belowground biomass, geographic location, forest type, and others. The development of this dataset facilitates in-depth understanding of the relationship between forest biomass and stand age, as well as their distribution characteristics in this region. The data were sourced from 118 literature articles and 282 sampling plots. Duplicate and outlier values were removed, and the plots were classified into coniferous forests, broad-leaved forests, and mixed forests based on dominant species or vegetation types. Through rigorous data integration and cleaning, the credibility and accuracy of the data are ensured, resulting in excellent data quality. This dataset can provide foundational data support for research on forest ecosystems on the Qinghai-Tibet Plateau, such as validating the simulation of carbon cycle processes in ecosystem models.
