摘　　要：阴山北麓荒漠草原地理区位特殊,既是我国阴山山地向蒙古高原的过渡带,也是半干旱区向干旱区气候的过渡区域,属于国家生态安全格局北方重要生态安全屏障区。了解区域内植物群落特征对探究荒漠草原生物多样性、草地生产力以及退化草原恢复具有重要意义。本文整理了2019–2022年阴山北麓站长期围封样地不同坡位植物群落生长季的野外调查数据,数据包括植物种类组成、高度、盖度、密度和地上生物量等。数据集的采集和处理过程严格遵循草地植物群落调查质量控制和规范。本数据集可为荒漠草原的管理和恢复提供科学依据和数据支撑。The desert steppe at the northern foot of Yinshan Mountain has a special geographic location,severing as a transition zone between the Yinshan Mountains of China and the Mongolian Plateau,as well as a transition zone from a semi-arid zone to an arid zone climate.The region is an important ecological security barrier in the northern part of the national ecological security framework.Understanding the characteristics of plant communities in the region is of great significance for exploring the biodiversity of desert steppe,grassland productivity,and the recovery of degraded grassland.In this paper,we collated the field survey data of plant communities in different slope positions of the long-term enclosure sample site during the growing season at the National Field Research Station at the Northern Foot of Yinshan Mountain from 2019 to 2022.The dataset covers plant species composition,height,coverage,density and aboveground biomass.The collection and processing of the dataset strictly adhered to the quality control standards and specifications for grassland plant community surveys.This dataset is expected to provide a scientific basis and data support for the management and restoration of desert steppe ecosystems.
