青海湖流域植被地面实测数据集的采集与组成(2021–2022)

In Situ Vegetation Dataset in Qinghai Lake Basin(2021–2022)

青海湖流域是青藏高原东北部重要的自然地理区域,也是青海省“两屏三区”生态安全格局的重要组成部分。作者于2021年8月、2022年8月各自对流域内28个和29个样地进行植被调查和监测,得到青海湖流域植被监测数据集。该数据集包括:(1)植被监测点的地理位置与概况;(2)温性草原、温性荒漠草原、高寒草原、温性荒漠、山地草甸和低地草甸的植被类型结构;(3)植物科、属、种数量统计;(4)青海湖自然保护区、普氏原羚活动区植被生物量统计;(5)植被结构、生物量年度比较表。数据集存储为.shp和.xlsx格式,由8个文件组成(Excel文件包括35个表格数据),数据量为124 KB(压缩为1个文件,102 KB)。

Qinghai Lake basin is an important natural geographical area in the northeast of the Qinghai-Tibet Plateau and a crucial component of ecological security pattern in Qinghai province.In August 2021 and August 2022,the authors conducted vegetation survey on 29 sample sites in the Basin.The dataset includes:(1)The geographical location and overview of vegetation surveying sites;(2)The vegetation type structure of temperate grassland,temperate desert grassland,alpine grassland,temperate desert,mountain meadow and lowland meadow;(3)Statistics on the number of plant families,genera and species;(4)Vegetation biomass statistics of Qinghai Lake Nature Reserve and Przewalski’s gazelle activity area;(5)Annual vegetation structure and biomass.The dataset is archived in.shp and.xlsx data formats,and consists of 8 data files with data size of 124 KB(Compressed into one file with 102 KB).
