青藏高原禁牧后生态系统恢复数据集（2005-2021）

基于对禁牧草地变化相关文献的检索，构建了禁牧后生态系统恢复数据集。该数据集包含了136项研究，主要聚焦于中国“退牧还草”项目的多个地区，其中涵盖了29个青藏高原的样点。收集的信息包括数据源、地点、土壤类型、优势种、草地类型、位置、气候数据、禁牧年限、土壤有机碳和总氮、地上和地下生物量、土壤表层深度、土壤容重等，进一步计算了土壤碳储量、土壤氮储量、地上和地下生物量碳等重要指标。该数据集有助于深入理解禁牧对土壤和植被生物量的影响。数据来源于涵盖2005年至2021年的相关文献，经过认真的数据整合与清洗，保障了数据的可信度与准确性，数据质量优良。该数据库对于评估禁牧政策对草原生态系统恢复的效果具有重要意义。未来，这些数据可用于生态过程模型的验证、草原管理政策制定以及相关生态环境保护工作的指导，为可持续草原管理提供科学支持。

Based on a literature search on changes in grazing-excluded grasslands, a dataset for post-grazing exclusion ecosystem restoration was constructed. This dataset includes 136 studies, mainly focusing on multiple regions of China's "Returning Grazing Land to Grassland" Program, covering 29 sampling sites on the Qinghai-Tibet Plateau. The collected information covers data sources, sampling locations, soil types, dominant plant species, grassland types, geographic positions, climatic data, grazing exclusion duration, soil organic carbon, total nitrogen, aboveground and belowground biomass, topsoil depth, soil bulk density, and more. Furthermore, critical indicators including soil carbon storage, soil nitrogen storage, and carbon stocks in aboveground and belowground biomass were derived from the raw data. This dataset facilitates in-depth understanding of the impacts of grazing exclusion on soil and vegetation biomass. The data were sourced from relevant literature spanning 2005 to 2021, and underwent rigorous data integration and cleaning to ensure its reliability and accuracy, resulting in excellent data quality. This dataset holds significant importance for evaluating the effects of grazing exclusion policies on grassland ecosystem restoration. In the future, these data can be used for the validation of ecological process models, the formulation of grassland management policies, and guidance for related ecological and environmental protection efforts, providing scientific support for sustainable grassland management.
