Abstract:  In order to analysis the temporal and spatial evolution characteristics and influencing factors of groundwater level in the mountain-front alluvial plain of Hutuo River in Shijiazhuang under the influence of human activities, based on the data of precipitation, groundwater level depth, groundwater exploitation, population and GDP in the study area, the average groundwater level variation map and groundwater flow field of different stages are drawn, and the temporal and spatial evolution characteristics of groundwater flow field are discussed. On this basis, the mechanisms by which human activities (groundwater extraction, artificial governance), natural factors (precipitation) and other factors (population, GDP, land-use type) influence the dynamics of the groundwater level are fully analised. The results show that: 1) On the time scale, the buried depth of groundwater level in the study area increases slowly from 1980 to 2000, increases rapidly from 2000 to 2015, and decreases from 2015 to 2021, and 2016 is the turning point. 2) Groundwater funnel area in Shijiazhuang urban area is large from 1980 to 2015, and groundwater confluence occurs in the funnel area. After 2015, groundwater funnel area in the study area gradually decreases and the confluence gradually disappears. 3) Precipitation and agricultural exploitation of groundwater are the dominant factors in the change of groundwater table from 1980 to 2000, industrial exploitation of groundwater is the dominant factor from 2000 to 2015, and artificial governance is the dominant factor from 2015 to 2021. 4) Population, GDP and land use types indirectly affect the groundwater depth in the study area, and the variation of groundwater depth in the mountain-front alluvial plain of Hutuo River in Shijiazhuang has obvious stage characteristics.
