摘要
在全球气候变化与碳中和目标背景下,准确评估干旱与半干旱生态系统碳储量变化对国家碳预算具有重要意义。本数据集利用干旱生态系统模型AEM(Arid Ecosystem Model)模拟了中国北方和黄河流域的碳储量,空间分辨率为10km×10 km,研究区包括中国北方和黄河流域,分别是新疆维吾尔自治区、西藏自治区、青海省、甘肃省、内蒙古自治区、宁夏回族自治区、辽宁省、黑龙江省、吉林省、河北省、陕西省、山西省、四川省、河南省、山东省和北京市。数据集包含了总碳库、植被碳库、土壤碳库和凋落物碳库。数据集在构建过程中引入多源气候与植被数据驱动模型,并结合实测数据开展交叉验证与不确定性分析,确保其科学性与可靠性。本数据集的建立和共享,为区域生态系统碳储量评估,生态系统质量评估提供了重要的基础数据。本数据集的发布为深入理解中国北方和黄河流域生态系统的碳循环提供了科学依据,并为生态保护策略的制定提供了支撑,同时助力国家碳预算估算和可持续农业政策的制定。
Under the backdrop of global climate change and carbon neutrality targets,accurately assessing carbon stock changes in arid and semi-arid ecosystems is crucial for national carbon budget estimations.This dataset was developed using the Arid Ecosystem Model(AEM)to simulate carbon storage in northern China and the Yellow River Basin with a spatial resolution of 10 km×10 km.The study area includes northern China and the Yellow River Basin,namely Xinjiang Uygur Autonomous Region,Xizang Autonomous Region,Qinghai Province,Gansu Province,Inner Mongolia Autonomous Region,Ningxia Hui Autonomous Region,Liaoning Province,Heilongjiang Province,Jilin Province,Hebei Province,Shaanxi Province,Shanxi Province,Sichuan Province,Henan Province,Shandong Province and Beijing.The dataset includes total carbon storage,as well as the vegetation carbon pool,soil carbon pool,and litter carbon pool.The dataset was developed by integrating multi-source climate and vegetation data to drive the model,and further validated through cross-verification with field observations and uncertainty analysis to ensure its scientific robustness and reliability.This study aims to support the analysis of climate change and rising atmospheric CO_(2)impacts on carbon storage in the arid and semi-arid regions of northern China and the Yellow River Basin.It provides a scientific foundation for understanding regional carbon cycles and for formulating ecological protection and carbon management strategies.Furthermore,the dataset serves as an important baseline resource for regional ecosystem carbon storage assessments and ecosystem quality assessments.The publication of this dataset provides a scientific foundation for understanding the carbon cycle in northern China and the Yellow River Basin.And it supports the formulation of ecological conservation strategies,contributes to national carbon budget estimations and informs the formulation of sustainable agricultural policies.
