Analysis on Water Security and Prediction of Water Demand in Northern Shaanxi Province

ZHANG Xing-yu,CAO Ming-ming, LEI Ming(Department of Urban and Resources,Northwest University,Xi'an 710069,China)  
Water is a basic living and production material in the socio-economic system,and also is the limiting factor in socio-economic development further.The Loess plateau of the northern part of Shaanxi province is facing the water shortage problem.In this paper,a preliminary analysis of water security situation in Northern Shaanxi has been maked by calculating of Water Poverty Index(WPI) and Water Stress Index(WSI),then the living,production and eco-environmental water demands in 2010 and 2020 were predicted.Water resource available in Northern Shaanxi was used to calculate the Index of Water Supply and Demand(IWSD).The IWSD is-0.13,-0.16 in 2010,2020.Which indicated the status of the development and utilization of water resource in Northern Shaanxi could not carry the socio-economicsystem. In conclusion,in order to ensure water resource sufficient to support the socio-economic systems in the northern part of Shaanxi province,the efficiency of development and utilization of water resource of should be enbanced to increase the volume of available water resource.
