Abstract In order to solve the problem of the serious groundwater over-exploitation, a series of comprehensive management measures have been implemented in Hebei Province. But how to effectively persevere in the governance work in the long run depends on scientific and rational evaluation. Therefore, to realize the process evaluation of governance effect based on the comprehensive integrated platform, the process of groundwater governance effect evaluation model was put forward, meanwhile, the evaluation index system for themed evaluation was established, and component technology along with integrated technology as used to realize the componentization for evaluation methods. Taking Hengshui city as an example, and using grey relational evaluation and impact factor correlation analysis method, the evaluation for governance effect during 2013—2017 was carried out. Four evaluation themes including the groundwater environment theme, the water resource utilization theme, the soil environment theme and the social economic theme were applied. The results show that the groundwater over-exploitation has been effectively alleviated since 2014, the evaluation grades of 2016 and 2017 are good, and the governance effect is obvious. The process evaluation of governance effects provides scientific evidence for the prevention and control of groundwater over-exploitation, thus promoting the sustainable development of the groundwater resources.
