摘要/Abstract

摘要：

理解植物化学计量特征的分布格局对于揭示其养分分配策略及预测植物对环境变化的响应具有重要意义。作为雅鲁藏布江中游地区的代表性灌木, 砂生槐(Sophora moorcroftiana)在该地区发挥着重要的防风固沙、保持水土等生态功能。本研究对砂生槐灌丛的19个样地57个样方进行了群落调查和样品采集, 并测定了灌木和土壤的碳(C)、氮(N)、磷(P)含量, 整合为西藏雅鲁藏布江中游砂生槐群落特征与C、N、P化学计量特征数据集。砂生槐的群落特征包含样地信息、群落类型及每株灌木的株高、冠幅及物候期, 共计1,544条数据; 测定得到砂生槐不同器官(叶、枝、根)的C、N、P化学计量特征数据, 共计166条; 测定得到不同深度土壤化学计量特征及pH值数据共191条。该数据集可为深入研究雅鲁藏布江中游砂生槐的植被特征以及化学计量特征提供原始数据。

Abstract

Understanding the distribution patterns of plant stoichiometric characteristics is significant for revealing their nutrient allocation strategies and predicting plant responses to environmental changes. As a representative shrub species in the middle reaches of the Yarlung Zangbo River, Sophora moorcroftiana plays crucial ecological roles in windbreak and sand fixation, as well as soil and water conservation in this region. In this study, we conducted community surveys and sample collections across 19 plots and 57 quadrats of Sophora moorcroftiana shrublands. Carbon (C), nitrogen (N), and phosphorus (P) contents were measured in both shrub tissues and soils, which were compiled into the C, N, and P stoichiometric characteristic dataset of Sophora moorcroftiana communities in the middle reaches of the Yarlung Zangbo River. The community characteristic dataset includes community type, plant height, crown width, and phenological phase for each shrub individual, totaling 1,544 records. The stoichiometric measurements for different shrub organs (leaf, branch, root) yielded 166 records. Soil stoichiometric characteristics and pH values across different depths were measured, providing 191 records. This dataset offers primary data resources for in-depth studies of vegetation patterns and stoichiometric traits of Sophora moorcroftiana in the middle reaches of Yarlung Zangbo River.
