摘要：

草原不仅是最大的陆地生态系统，而且也是生物多样性最为丰富的生态资源。草原监测是对草原生产要素及其动态变化进行系统地观测、监测和记录，旨在阐明其联系及发展规律。内蒙古大草原是目前世界上草原类型最多、保存最完整的草原之一，是我国重要的畜牧业生产基地。在草地生态系统中，土壤养分综合反映了土壤的基本属性和本质特征，研究不同草原类型土壤养分变化特征不仅反映植株群落对草原土壤健康的影响情况，同时为土壤、植被恢复形式、速度和方向等提供依据。目前，对土壤养分的研究多见于农业种植区域，草地土壤养分的研究数量较少。以内蒙古草地为例，相关研究主要聚焦于微生物多样性、温室气体等议题而鲜少涉及土壤养分，相关数据供给也非常有限。本数据集针对内蒙古自治区8个不同“区域-草地类型”草地在返青期、旺盛期与枯萎期的有效磷、速效钾、全氮、有机质、全盐以及pH值等土壤养分特征，所涉草地涉及温性草甸草原、荒漠草原、天然草滩、五花草甸草原和人工牧草种植地5种典型草原类型。数据集数据可为草地资源可持续利用研究与实践提供支撑。

Abstract:

Grassland is not only the largest terrestrial ecosystem, but also the most diverse ecological resource. Grassland observation monitoring is a systematic observation, monitoring, and recording of grassland production factors and their dynamic changes, aiming at elucidating their connections and development patterns. The Inner Mongolia grassland is currently one of the most diverse and well preserved grasslands in the world, and is an important livestock production base in China. In grassland ecosystems, soil nutrients comprehensively reflect the basic attributes and essential characteristics of soil. Studying the changes in soil nutrients of different grassland types not only reflects the impact of plant communities on grassland soil health, but also provides a basis for soil and vegetation restoration forms, speeds, and directions. At present, research on soil nutrients is mostly found in agricultural planting areas, but there is relatively little research on grassland soil nutrients. Taking Inner Mongolia grassland as an example, relevant research mainly focuses on issues such as microbial diversity and greenhouse gases, with little involvement in soil nutrients, and the supply of relevant data is also very limited. This dataset focuses on the soil nutrient characteristics of available phosphorus, available potassium, total nitrogen, organic matter, total salt, and pH value of eight different "regional grassland types" grasslands in Inner Mongolia Autonomous Region during the turning green, vigorous, and withering stages. The involved areas include five typical grassland types. The grasslands include temperate grassland, desert grassland, natural grassland, five flower grassland, and artificial grassland planting areas. The dataset can provide support for the research and practice of sustainable utilization of grassland resources.
