青藏高原植物群落样方调查数据集（2020）

青藏高原植物群落样方调查数据集（2020）由第二次青藏科考任务三专题六的科考队于2020年8月野外调查完成，空间跨度为：北纬30.35°- 36.52°，东经79.70°- 101.69°。数据集覆盖了灌丛、草地和农田等植被类型，共75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2条，草本层数据812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。

The 2020 Qinghai-Tibet Plateau Plant Community Quadrat Survey Dataset was completed by the scientific expedition team of Theme 6, Task 3 of the Second Qinghai-Tibet Plateau Scientific Expedition during field surveys conducted in August 2020. Its spatial extent ranges from 30.35°N to 36.52°N in latitude and 79.70°E to 101.69°E in longitude. The dataset covers major vegetation types including shrublands, grasslands and farmlands, with a total of 75 sampling plots. It consists of three components: plot information, shrub layer quadrat data and herb layer quadrat data. Specifically, there are 2 records for the shrub layer and 812 records for the herb layer. The surveyed variables include species composition, species fractional coverage, average height of individual species, average crown width of shrubs, and total community coverage.
