Yulin city is an enrichment region of energy resources, and an extremely vulnerable area as well in China. The energy resources' exploitation and eco-reconstruction has seriously restricted by water resources. Based on fuzzy mathematical and AHP method, it has estimated the water resources intimidation from 2000 to 2005 in Yulin city. The results show that water resource intimidation already approaches to or exceeds the heavy stress degree, and presents an increasing trend. In the basis of the analysis of the industrial structure and its characteristics of water use, the results indicates that agriculture has the biggest proportion in water use, along with the industry scale enlarging and eco-reconstruction, both industrial and ecological water use has been increasing. The interaction mechanism between water resources and society-economy development tells us that: the development of economy has restricted by water resources, which propels the industry to move to the direction of low water demand and high efficiency; impelled by the aridification, agrotype has conversed from crops to grazing and forest; the industry changes to the low water demand and high efficiency types, meanwhile, the industry incomes would help development water-saving agriculture and transform water; the increase of water demand in society and economy produces many eco-environment problems, such as, the excess utilization and declining water level of groundwater.
