摘要
青海省湟水河作为黄河上游重要支流,发源于青海省海北藏族自治州海晏县,流经青海省西宁市和海东市,掌握湟水河流域植物群落本底数据对于评估青藏高原的生态系统功能与服务,研究其对全球环境变化的反馈作用有着重要意义。本文整理了2021-2022年夏季两次对西宁市和海东市以及海北藏族自治州海晏县的湟水河流域草本植物群落的野外调查数据,共计455个样方,4113条植物数据,其中包括了277个植物物种(隶属于55科172属),并计算了455个草本植物样方的相关多样性指数(即物种丰富度、Shannon-Wiener指数、Pielou指数和Simpson指数),为青藏高原湟水河流域植被群落及其生态系统研究和生物多样性保护与管理提供了本底信息。
As a key tributary of the upper Yellow River,originating from Haiyan County,Tibetan Autonomous Prefecture of Haibei,Qinghai Province,Huangshui River flows through Xining City and Haidong City in Qinghai Province,China.Obtaining the basic data of plant communities in Huangshui River Basin is critical to assessing the ecosystem functions and services of the Qinghai-Tibet Plateau and studying its feedback effect on global environmental changes.In this paper,we collated the data from two field surveys of herb communities conducted in the summers of 2021 and 2022 in Huangshui River Basin in Xining City,Haidong City and Haiyan County of Haibei Tibetan Autonomous Prefecture,with a total of 455 quadrats comprising 4,113 records and 277 plant species(55 families and 172 genera).We then calculated the diversity indexes(i.e.species richness,Shannon-Wiener index,Pielou index,and Simpson index)of plant communities.The results can serve as a guide for the future research on plant communities and ecosystems,and biodiversity management in Huangshui River Basin of the Qinghai-Tibet Plateau.
