Abstract

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.
