Abstract: A proposed groundwater source area in Kuancheng county，Chengde city，Hebei province was taken as research area.Agricultural water is one of the largest water users in research area，which occupies a large proportion in production process，which restricts development of economy and agriculture.Resource evaluation and comprehensive evaluation of water quality will play an important role in water conservation planning and water resource utilization.Hydrogeological conditions，chemical characteristics of groundwater and other basic conditions were fined out.Follow objective law，according to actual field exploration to obtain hydrogeological data to determine parameter values，hydrogeological model was established.Groundwater resource was calculated and evaluated by natural recharge water balance method，and recoverable groundwater resource evaluation was calculated by mining experiment method to calculate.Groundwater quality in the study area was evaluated by results of actual water samples.Finally，some suggestions for construction of groundwater source were given，and basis for development of local social economy was provided.
