本数据集收录了2025年7月与8月在试验田内开展的生物多样性样方调查数据，涵盖12个标准样方的植被群落结构特征。调查通过实地布设1m×1m的标准样方，对样方内所有维管植物的种类及个体数量进行系统记录，并计算了多样性指标，包括物种丰富度（S）、Shannon-Wiener指数（H′）、Simpson指数（D）和Pielou均匀度指数（J）。该数据集既包含原始观测数据（物种名录及数量），也包括经过统计加工的群落多样性指数结果。通过对比不同处理样方与对照样方的数据，可以揭示人工干预、管理措施或环境差异对群落物种组成与生态系统稳定性的影响。该数据集适用于生态学研究与恢复生态评价。

This dataset includes both raw observation data (species list and quantity) and statistically processed community diversity index results. By comparing data from different treatment plots and control plots, the impact of human intervention, management measures, or environmental differences on community species composition and ecosystem stability can be revealed. This dataset is suitable for ecological research and ecological restoration evaluation.
