Abstract: Water resources are foundation and important guarantee for development of a region, evaluation and analysis of regional water resources is of great significance for formulation of a reasonable water resources strategy．Water footprint theory was introduced and structural analysis, spatial and temporal change analysis and comprehensive impact factor analysis and evaluation of agricultural water footprint of Jingtai County were carried out．Analysis of structural changes of water footprint showed that, total agricultural water footprint of Jingtai County as a whole showed a growing trend from 2010 to 2019, among which water footprint of cash crops was the highest, water footprint of livestock products was the second highest, and water footprint of food crops was the lowest．From 2010 to 2019, water footprint of food crops increased by 102%, water footprint of livestock products increased by 38%, and water footprint of cash crops increased by 22%．Analysis results of spatial change of agricultural water footprint showed that, between 2010 and 2019, agricultural water footprint of Jingtai County showed a shift from east to west, and center of gravity of agricultural water consumption shifted from east to west．Growth type of agricultural water footprint of each township was mainly in the western region of Jingtai County, decline type was in the central and eastern region, fluctuating type was in the northeast region．Principal component influence factor analysis results showed that, the first principal component influence contribution rate was as high as 64.997%, while the second and third principal components were 11.333% and 10.504% respectively．It showed that agricultural water footprint of Jingtai County was mainly influenced by the first principal component factors, with economic factors and agricultural production factors having the greatest influence on agricultural water footprint of Jingtai County, which were main influencing factors; followed by the second and third principal component influencing factors, which were climatic factors and demographic factors respectively, with relatively low influence．There is more room for improvement in the use of agricultural water resources in Jingtai County．Starting from structure and influencing factors of agricultural water footprint, specific influencing factors were analyzed to adjust agricultural structure and promote sustainable use of regional agricultural water resources.
