摘　　要：蒙古高原地处欧亚大陆腹地的高原地带,植被覆盖包括森林、森林草原、典型草原、荒漠草原、戈壁荒漠等,利用遥感FAPAR数据监测蒙古高原生物多样性变化是一种有效的方法。该数据集基于FAPAR数据,利用ArcGIS及Python程序进行月最大值合成,结合动态生境指数DHI,形成了2001-2018年500米动态生境指数数据集,包含蒙古高原地区长时间序列DHI空间分布情况。该数据集的空间范围包括中国内蒙古自治区、蒙古国全部以及俄罗斯南部,时间序列为2001-2018年,数据存储为.tif格式。通过数据共享,为蒙古高原生物多样性、物种丰富度的空间分布变化规律及未来物种分布的预测提供数据支撑。Located in the plateau region of the hinterland of Eurasia,the Mongolian Plateau has vegetation covers,including forest,forest steppe,typical steppe,desert steppe,and gobi desert,etc.It is effective to use FAPAR data to monitor the changes of biodiversity on the Mongolian Plateau.Based on FAPAR data,we used ArcGIS and Python program to synthesize monthly maximum values,and in combination with the dynamic habitat index(DHI),we obtained a dataset of dynamic habitat indexes with a resolution of 500m from 2001 to 2018,including the spatial distribution of long-term series DHI on the Mongolian Plateau.The geographic scope of the dataset covers Inner Mongolia Autonomous Region of China,all over Mongolia and Southern Russia,with a time series of 2001-2018.The data is stored in“.tif”format.Through data sharing,the dataset is expected to provide data support for the research on the spatial distribution of the biodiversity and species richness as well as the prediction of species distribution in the future on the Mongolian Plateau.
