土壤有机碳库是陆地生态系统碳库中最大、最为活跃的部分,在全球碳循环过程和全球气候变化中起着重要的作用。中国西北旱区位于欧亚大陆的腹地,生态系统极其脆弱,对气候变化的响应也极为敏感,是近年来众多学者关注的热点地区,土壤有机碳储量估算以及空间分布特征日益成为该区域的研究焦点之一,但是数据共享不足与实测数据相对缺乏是造成研究结果不确定性的重要因素。在收集中国生态系统研究网络(CERN)位于中国西北六省区的农田、荒漠、草地生态系统野外科学观测研究站土壤长期观测数据的基础上,通过筛选、质量控制后,采用有机碳估算模型计算生成了中国西北干旱区典型生态系统土壤有机碳密度数据集。本数据集涵盖了11个站点2005-2020年各类长期观测样地的表层(0-20 cm)和剖面分层土壤有机碳密度数据,以期为中国西北干旱区土壤碳储量估算和碳循环过程研究提供有价值的实测数据。
A dataset of soil organic carbon density of typical ecosystems in the arid areas of Northwest China from 2005 to 2020
As the largest and most active part of the terrestrial ecosystem carbon pool,the soil organic carbon pool plays an important role in the global carbon cycle and global climate change.The arid areas in Northwest China,located in the hinterland of Eurasia,are characteristic of extremely fragile ecosystems that exhibit highly sensitive responses to climate change.These areas have become a focal point of interest for many scholars in recent years.The estimation and spatial distribution of soil organic carbon storage have increasingly become a key research focus.However,a scarcity of shared data and measured data contribute significantly to the uncertainty in research findings.Based on the long-term soil observation data collected from the ecological field stations of the China Ecosystem Research Network(CERN)located in five provinces and regions of northwest China,we produced a dataset of soil organic carbon density of typical ecosystems in the arid areas of Northwest China using the organic carbon estimation model.This dataset contains the soil organic carbon density data of topsoil(0-20 cm)and soil profile of various long-term observation plots at 11 ecological field stations from 2005 to 2020,so as to provide valuable measured data for the estimation of soil carbon storage and the study of carbon cycle process in the arid area of Northwest China.
