摘要: 柴达木盆地地处青藏高原东北部, 为高原型巨大封闭盆地, 植被以荒漠为主, 兼具沼泽湿地、盐生草甸和山地草原等。为更精细地展示柴达木盆地地区植被的物种组成、群落特征及其分布格局, 该文利用2022年夏季第二次青藏高原综合科学考察及2014年青藏高原资料匮乏区综合科学考察的野外数据, 共157个样地, 458个样方, 整合为柴达木盆地植物群落样方数据集。通过数据的整理与汇编, 共得到185条物种信息, 其中物种数最多的科依次为菊科(39种)、禾本科(33种)、豆科(17种)、苋科(16种)及十字花科(10种), 包含物种数最多的属依次为针茅属(Stipa)、蒿属(Artemisia)、黄耆属(Astragalus)、棘豆属(Oxytropis)和风毛菊属(Saussurea)。植物生活型组成以草本居多, 占78.37%; 区系地理成分以亚洲中部种占优势, 占41.62%。基于群落学-生态学分类原则, 157个样地可以归为4个植被型组, 7个植被型, 11个植被亚型, 40个群系。该数据集可为深入研究柴达木盆地植被特征、《中国植被志》编研、青藏高原及全国植被图绘制提供最原始的基础数据。

Abstract: Located in the northeast of the Qinzang Plateau, Qaidam Basin is a huge plateau-type closed basin. The vegetation is dominated by desert, including swamp wetlands, halophytic meadows and montane grasslands. In order to show the species composition, community characteristics and distribution pattern of vegetation in Qaidam Basin in more detail, this paper uses the field data of the Second Tibetan Plateau Scientific Expedition and Reserch of 2022 and the Comprehensive Scientific Investigation of the Data-scarce Area of the Qinghai-Tibet Plateau of 2014, including 157 sample plots and 458 sample plots, which are integrated into the sample data set of plant communities in Qaidam Basin. Through the collation and compilation of data, a total of 185 species information was obtained, among which the families with the largest number of species were Asteraceae (39 species), Poaceae (33 species), Fabaceae (17 species), Amaranthaceae (16 species) and Brassicaceae (10 species) , and the genera with the largest number of species were Stipa, Artemisia, Astragalus, Oxytropis and Saussurea. The composition of plant life form is dominated by herbs, accounting for 78.37%. The species of middle Asia account for 41.62% of the geographical composition of the flora. Based on the phytocoenological-ecological principles, 163 sample plots can be classified into 4 vegetation formation groups, 7 vegetation formations, 11 vegetation subformations and 40 alliances. This data set can provide the most original basic data for the in-depth study of vegetation characteristics in Qaidam basin, the compilation and research of the Vegegraphy of China, and the mapping of Qingzang Plateau and the national vegetation map.
