青海湖流域31样地植被监测数据集(2018)的组成

Vegetation Monitoring Dataset from 31 Plots in Qinghai Lake Watershed(2018)

青海湖流域(97°50′E-101°20′E,36°15′N-38°20′N)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。流域生物多样性丰富,是青藏高原物种基因库,也是高原生态系统的典型区域。2018年,对流域内31个样点的植被进行了监测,包括样地的植被类型、高度、覆盖度、生物量、科、属、种等,得到青海湖流域31样地植被监测数据集(2018)。该数据集包括:(1)监测样地概况和样地位置数据;(2)温性草原、温性荒漠草原、高寒草原、温性荒漠、山地草甸、低地草甸和高寒草甸的植被类型结构;(3)七种地带性植被主要植物科、属、种数量统计;(4)青海湖自然保护区、鸟类栖息地、普氏原羚活动区植被生物量及可利用生物量统计;(5)温性草原、温性荒漠草原、高寒草原、温性荒漠植物结构、生物量年度比较。

The Qinghai Lake watershed(97°50’E-101°20’E, 36°15’N-38°20’N) is an important natural geographical region in the northeastern Qinghai-Tibetan Plateau. It is an important part of the ecological security of the Two Screens and Three Districts region in Qinghai province. The basin has a rich biodiversity and is a gene pool for Qinghai-Tibetan Plateau species, in addition to having a typical plateau ecosystem. Vegetation was monitored at 31 sample sites in the basin during 2018 and a vegetation monitoring dataset was obtained for the Qinghai Lake watershed. The dataset includes:(1) a profile of the sampling sites and location data;(2) the type of vegetation(temperate grassland, temperate desert grassland, alpine grassland, temperate desert, mountain meadow, lowland meadow and alpine meadow);(3) statistics for the main plant families, genera and species of the seven zonal vegetation types;(4) statistics for the biomass and available biomass of vegetation in the Qinghai Lake Nature Reserve, the various bird habitats and the active area for Przewalski’s gazelle;and(5) an annual comparison of the plant structure and biomass of the temperate steppe, temperate desert steppe, alpine steppe and temperate desert.
