Discussion on sustainable use of Xihe river underground water resource in Fuxin city;

According to the sustainable exploitation model of ground water resources and the dynamic model for the optimal allocation of irrigation system,the ground water resources of well-irrigation area is optimized among years, crops and different growing time of crops in North plain of China, where the inconsistency is extrusive between supply and demand of water resources.

According to different situatons, this paper discussed and analyzed the extraction and protection of ground water resources and poses the suitable protective measures.
