青藏高原植物群落样方调查数据集（2019）

青藏高原植物群落样方调查数据集（2019）由第二次青藏科考任务三专题六的科考队于2019年8月野外调查完成，空间跨度为：北纬36.02°- 38.07°，东经91.45°- 100.84°。数据集覆盖了森林、灌丛、草地、荒漠和农田等植被类型，共48个样地。数据集由四部分组成，包括样地信息、乔木层样方、灌木层样方和草本层样方。其中乔木层数据2条，灌木层数据63条，草本层数据101条。调查条目包括物种组成，物种分盖度，物种平均高度，灌丛平均冠幅和群落总盖度。

2019 Qinghai-Tibet Plateau Vegetation Community Quadrat Survey Dataset was completed in August 2019 during field surveys by the scientific expedition team of Theme 6, Task 3 of the Second Qinghai-Tibet Plateau Scientific Expedition Program. Its spatial extent ranges from 36.02°N to 38.07°N and 91.45°E to 100.84°E. The dataset covers major vegetation types including forests, shrublands, grasslands, deserts and farmlands, with a total of 48 sampling plots. It consists of four components: plot information, tree-layer quadrat data, shrub-layer quadrat data, and herb-layer quadrat data. Specifically, there are 2 tree-layer records, 63 shrub-layer records, and 101 herb-layer records. The survey metrics include species composition, species percentage coverage, average height of each species, average crown width of shrubs, and total community vegetation cover.
