摘　　要：干旱区是对气候变化最敏感的陆地生态系统之一,生态系统碳库动态是区域碳源、碳汇特征最直观的表现,干旱区生态系统有机碳库的估算及其动态研究在区域乃至全球尺度的碳循环研究中都具有重要的科学意义。研究区大致空间范围为30°N-50°N、70°E-110°E,包括中国新疆、甘肃西北部以及内蒙的西南部。本文收集了MERRA、ERA-Interim和CFSR三套气象数据驱动干旱区生态系统模型AEM得到的1980-2014年中国干旱区碳库分布数据(空间分辨率50 km×50 km),并和现有文献资料对数据质量进行了分析和评估。本数据集可作为中国干旱区碳库变化的调查资料,为该区域生态系统研究提供基础数据支撑。本数据集服务于丝绸之路经济带建设的国家需求,对社会经济稳定和可持续发展具有重要的现实意义。Arid region is known for its terrestrial ecosystems highly sensitive to climate change.The dynamics of ecosystem carbon pools most intuitively reflect regional carbon source/sink characteristics.Studies on the estimation and dynamics of organic carbon pools in arid region ecosystems have important scientific implications for carbon cycle studies at both regional and global scales.The approximate spatial range of the study area is 30°N-50°N and 70°E-110°E,covering Xinjiang,northwest Gansu,and southwest Inner Mongolia of China.This paper collects the distributional data of carbon stocks in China's arid regions from 1980 to 2014(spatial resolution:50km),obtained from the arid ecosystem model(AEM)based on three sets of meteorological data-MERRA,ERA-Interim,and CFSR.The data obtained are then validated against data from existing literature.This datasets can be used as survey data to understand the changes of carbon stocks in the arid regions of China,providing basic data support for regional ecosystem studies.It also serves national needs in the construction of the Silk Road Economic Belt and has important practical significance for socioeconomic stability and sustainable development.
