In order to reduce the impact of human activities on groundwater and realize the sustainable utilization of groundwater resources, it is necessary to dynamically evaluate the groundwater exploitation intensity from spatial and temporal perspectives. Based on set pair analysis, a spatiotemporal dynamic evaluation model was established, and the dynamic evolution process of the degree of identity, degree of discrepancy and degree of contrary was discussed based on the second order partial connection number, by which the main factors affecting the exploitation intensity were identified. The results show that the groundwater exploitation intensity in Daxing District kept increasing from 2006 to 2016, and central region > southern region > northern region on the spatial distribution. The spatial and temporal distribution characteristics of the intensity level influenced by the population, industrial output value and tertiary industry output value were ranked as follows: northern region > central region > southern region, and that by the agricultural planting area and number of wells were southern region > central region > northern region. According to the identification results of the second order partial connection number, the influence of the population, industrial output value and tertiary industry output value were improving, but that of the agricultural planting area and number of wells were weakening. The spatiotemporal dynamic evaluation model constructed in this paper can accurately reflect the groundwater exploitation intensity level and its dynamic evolution process in the study area, and the calculation is simple, so it is worth popularizing.
