The Water Resources Security Assessment of Ningxia Based on Water Footprint Theory

The thesis calculates the water footprint of 2012 in Ningxia,and evaluates the current situation of water resources utilization based on water footprint theory,computation model and assessment indicator of water resources security according to the statistical data of 2012.The study shows that:In 2012,the total number of Ningxia's water footprint was 100.894×108 m3.And the average number was 1 558.953 m3 per capita;The largest industry of water consumption was agriculture,whose water footprint reached up to 84.715×108 m3,occupying 63.086% of the total water footprint in Ningxia;The degree of water resources scarcity and water resources stress indicator were 93.377%and 124.280%respectively,which demonstrated the unsustainable state of water use.In response to these circumstances,some measures,such as adjusting the industrial structure,transforming the consumption structure and perception,diverting water from outside basin,developing virtual water trade and the like,should be taken to realize the sustainable utilization of water and ensure the safty of water resources.
