摘　　要：本研究收集了通过干旱区生态系统模型AEM(Arid Ecosystem Model)模拟得到的1980-2014年中国干旱半干旱区生态系统有机碳储量、碳动态数据,包括总碳储量、植被碳储量、土壤有机碳储量和凋落物碳储量。空间分辨率50 km×50 km,研究区(27.6°-53.6°N,73.4°-127.5°E)从中国西部到东北部,跨越了整个新疆、甘肃、内蒙古、西藏、青海,以及黑龙江、辽宁和吉林的西部,河北、陕西、山西、宁夏北部区域,约占国土面积的一半。本数据集是中国有机碳储量的重要组成部分,对维持我国干旱半干旱区生态系统可持续发展具有重要的科学的意义。The organic carbon storage and carbon dynamic datasets in arid and semiarid regions of China were simulated by the Arid(Arid Ecosystem Model),a unique arid ecosystem model.This dataset collects the organic carbon stocks and carbon dynamics data of ecosystems in arid and semi-arid regions of China from 1980 to 2014,including total carbon storage,vegetation carbon storage,soil organic carbon storage and litter carbon storage.With a spatial resolution of 50 km×50 km,the study area(27.6°-53.6°N,73.4°-127.5°E)spans the whole of Xinjiang,Gansu,Inner Mongolia,Tibet,Qinghai,and Heilongjiang and Liaoning.In the west of Jilin,Hebei,Shaanxi,Shanxi,and northern Ningxia account for about half of the country's land area.This dataset is an important part of China's organic carbon stocks.This dataset has important scientific significance for maintaining the sustainable development of ecosystems in arid and semiarid regions of China.
