Mineral resources of the blown-sand region in the northern Shaanxi province, national energy and chemical industry base, are abundant. Because the region is in the arid and semi-arid climate zone, rare precipitation and intense evaporation, so its environment is fragile and water resources are key confinement factors to its economical development. Directed by dynamic theories of groundwater, based on principle of sustainable development of water resource and pattern of water resource conversion among atmospheric precipitation, surface water and groundwater, combining with hydrogeological conditions, this paper evaluated the allowable withdrawal of regional groundwater resources of ecological safety-based by numerical stimulation theories and method of groundwater flow on the purpose of sustainable utilization of water resources, and proposed exploitation programs. These research achievements above provide scientific evidence for rational exploitation of groundwater resources in the blown-sand region of the northern Shaanxi province, these have important significance to sustainability of environment protection, industry and agriculture production and economy development.
