摘要:

兰州市南北两山地处黄土高原最西端, 植被以草地为主, 兼具灌丛、荒漠及森林等。为揭示其详细的植被类型、群落结构及其地理分布特征, 该研究采用野外样线、典型样方调查与室内分析相结合的方法, 对兰州市南北两山的植被状况进行了全面调查, 并汇总了植物群落样方数据集(共72个样地)。通过数据整理, 发现兰州市南北两山共有植物4门107科378属713种(含种下单位), 其中, 栽培植物有59科124属218种, 野生植物有79科282属495种; 植物生长型以草本植物为主(68.32%), 其生活型主要为多年生草本(66.11%)。木本植物(31.68%)的生活型主要为落叶植物(84.30%); 基于群落-生态学分类, 兰州市南北两山植被可以划分为4个植被型组, 9个植被型及32个群系, 其中, 针叶林群系5个、阔叶林群系5个、灌丛群系10个、草原群系5个、草甸群系1个、荒漠群系6个。该数据集可以为西北干旱半干旱地区植物多样性及生态学研究提供本底资料, 为区域生态系统服务供给、生态环境质量提升以及社会经济可持续发展提供科学依据。

Abstract:

The northern and southern mountains of Lanzhou are located at the westernmost part of the Loess Plateau, with herbaceous vegetation as the dominant vegetation, along with shrubs, deserts, and forests. To reveal the detailed vegetation types, community structures, and their geographical distribution, this study used a combination of field sample lines, typical sample surveys, and indoor analyses to systematically investigate the plant communities of these two mountains. A dataset of plant community sample plots was compiled, totaling 72 plots. Through data analysis, a total of 713 plant species belonging to 107 families and 378 genera (including infraspecific units) across four phyla were identified in the northern and southern mountains. Among them, 218 species from 124 genera and 59 families were cultivated plants, and 495 species from 282 genera and 79 families of natural plants. Plant growth form was dominated by herbaceous plants (68.32%), with perennials comprising the majority (66.11%). Woody plants accounted for 31.68%, most of which were deciduous (84.30%). Based on community-ecology classification, the vegetation of the northern and southern mountains can be divided into 4 vegetation formation groups, 9 vegetation formations, and 32 alliances, including 5 needleleaf forest alliances, 5 broadleaf forest alliances, 10 shrubland alliances, 5 steppe alliances, 1 meadow alliance, and 6 desert alliances. This dataset provides essential baseline information for studying plant diversity and ecology in the arid and semi-arid regions of Northwest China. In addition, it serves as a scientific basis for regional ecosystem service supply, ecological environment quality improvement, and sustainable socioeconomic development.
