青藏高原植物群落样方调查数据集（2021）

青藏高原植物群落样方调查数据集（2021）由第二次青藏科考任务三专题六的科考队于2021年7月野外调查完成，空间跨度为：北纬28.89°- 32.16°，东经80.07°- 93.78°。数据集覆盖了灌丛、草地和荒漠三个植被类型，共54个样地。数据集由三部分组成，包括样地信息、灌木层样方和草本层样方。其中灌木层数据39条，草本层数据314条。调查条目包括物种组成，物种绝对分盖度，物种平均高度和灌丛平均冠幅。

The Qinghai-Tibet Plateau Plant Community Quadrat Survey Dataset (2021) was field-collected in July 2021 by the research team of Task 3, Topic 6 under the Second Qinghai-Tibet Plateau Scientific Expedition. Its spatial coverage spans from 28.89°N to 32.16°N latitude and 80.07°E to 93.78°E longitude. The dataset encompasses three vegetation types, namely shrubland, grassland and desert, with a total of 54 sampling plots. It consists of three components: plot metadata, shrub layer quadrat data and herb layer quadrat data. Among them, there are 39 entries of shrub layer data and 314 entries of herb layer data. The survey items include species composition, absolute fractional coverage of each species, average height of species, and average crown width of shrubs.
