长江源草地植被样方调查数据集（2020）

通过对长江源植被的调查及分析，评估不同放牧强度对高寒草甸的影响。于2020年8月野外调查设置植被调查样方，调查植被高度、多度、盖度及地上生物量，并在此基础上，计算了植被的Gleason指数、Shannon-Wiener指数、Simpson指数、Pielou指数，禾本科重要值、杂类草重要值、莎草科重要值及禾本科重要值。全面了解不同放牧强度下土壤及植被特征的响应，揭示草地利用强度对区域环境影响的程度和强度，并提出草地合理利用管理对策。

Through investigation and analysis of vegetation in the source region of the Yangtze River, this study evaluates the effects of different grazing intensities on alpine meadows. Vegetation survey quadrats were established during field surveys conducted in August 2020, and vegetation height, abundance, coverage, and aboveground biomass were investigated. Based on the collected data, the Gleason index, Shannon-Wiener index, Simpson index, and Pielou index of vegetation were calculated, along with the important values of Gramineae, forbs, Cyperaceae, and Gramineae. This study comprehensively clarifies the responses of soil and vegetation characteristics under different grazing intensities, reveals the extent and intensity of the impact of grassland utilization intensity on the regional environment, and proposes reasonable management strategies for grassland utilization.
