摘要:

垫状驼绒藜(Krascheninnikovia compacta)群落分布于人迹罕至的极端寒冷、干旱的高海拔地区, 是青藏高原高寒荒漠最为典型且分布较广的植被类型。该群落已有的研究多为定性描述, 均未提供珍贵的样方数据。本文以2018、2019及2022年野外调查数据和相关文献资料为基础, 记录整理了垫状驼绒藜群落的空间分布、群落特征、群落结构及其气候等环境特征, 构建了垫状驼绒藜群落数据集。数据集结果显示: (1)垫状驼绒藜群落主要分布在青藏高原的中昆仑山、北天山、阿尔金山、当金山山口; (2)垫状驼绒藜群落的高度、盖度、生物量和物种丰富度均相对较低, 22个典型样地共记录到种子植物29种, 分属11科22属; 其生活型以地面芽植物居多, 共18种, 占植物总种数的62.07%, 主要为多年生禾草和多年生杂类草; (3)群落结构简单, 恒有度 > 50%的仅有垫状驼绒藜, 灌木层、草本层都未出现次优势种, 伴生种、偶见种居多(93.10%); (4)群落垂直结构可划分为2层, 第一层是以垫状驼绒藜为主的稀疏垫状小半灌木, 第二层是稀疏的草本层; (5)群落的生长环境具有气候寒冷、降水少且集中于最暖季的高寒荒漠气候特点。本数据集是国内目前已知唯一垫状驼绒藜群落数据集, 是揭示垫状驼绒藜群落物种组成和结构等特征的重要凭证, 数据集中的地理气候信息和群落物种信息可为垫状驼绒藜群落研究及《中国植被志》的编研提供基础数据。

Abstract

The Krascheninnikovia compacta community is primarily distributed in extremely cold and arid high-altitude environments typically inaccessible to humans. It represents the most common and widely distributed type of vegetation in the alpine deserts of the Qingzang Plateau. Most investigations into this community take the form of qualitative descriptions, which fail to provide precious sample data. In order to generate a community dataset of K. compacta, this paper recorded and organized the spatial distribution, community characteristics and structure, and climate characteristics of this species based on field survey data collected in 2018, 2019, and 2022, along with a description of the relevant literature. The results showed that: (1) Krascheninnikovia compacta community was mainly found in the Central Kunlun Mountains of the Qingzang Plateau, the Northern Tianshan Mountains, the Altun Mountains, and the Dangjin Mountains Pass. (2) Krascheninnikovia compacta community had the relatively low values in community height, coverage, biomass and species richness. Our study identified 29 species of seed plants belonging to 11 families and 22 genera distributed among 22 typical plots. Hemicryptophytes were the dominant life form, with a total of 18 species, which accounted for 62.07% of all plants and primarily consisted of perennial grasses and perennial weeds. (3) The community structure was relatively simple due to only K. compacta having a consistent presence of more than 50% of all species. There were several subdominant species but mostly companion species and occasional species (93.10%) residing in the shrub layer and herb layer. (4) The vertical structure of the community can be divided into two layers. The first layer consists of a sparse cushioned small semi-shrub dominated by K. compacta, and the second layer consists of a sparse herb layer. (5) The growth environment of this community was characterized by a cold climate and little precipitation that is concentrated in the warmest quarter of the alpine desert climate. This dataset is the only known dataset describing the K. compacta community in China. It represents a valuable resource for studying the species composition and structure of the K. compacta community. The information regarding the geographic climate and community species in the dataset provides basic data for future investigation of Krascheninnikovia compacta community and compilation of Vegegraphy of China.

Database/Dataset composition This dataset consists of two files. File 1: A quadrat photo dataset of Krascheninnikovia compacta community, which is divided into 14 subfiles according to the survey plots. Each subfile includes quadrat photos, environment photos, and sample description of plot. It contains 97 quadrat photos and 14 quadrat descriptions in total. All subfiles are named after plot number and photos are named after plot-quadrat-replicate.
