Abstract: An in-depth study on water resources account and its development and utilization can provide theoretical basis and intellectual support for the regional social economy sustainable development.Based on the data of water resources, economy and population of Shaanxi Province from 2000 to 2017,the sustainable utilization of water resources was analyzed and studied by using the ecological footprint model of water resources.The results showed that from 2000 to 2017,the water resources ecological footprint in Shaanxi Province showed a slow rising trend.The cultivated land ecological footprint of water resources per capita was the mainly part and had a decreasing trend in recent years, while the ecological footprint of water resources per capita in industry, life, forestry, animal husbandry and fishery, urban public and ecological environment showed a stable increasing trend.The ecological footprint and ecological carrying capacity of water resources were quite different in the southern of Shaanxi, the northern of Shaanxi and Central Shaanxi.Among them, water resources state in the southern of Shaanxi was always the ecological surplus, while that in the northern of Shaanxi and Central Shaanxi were ecological deficit.In recent ten years, the utilization of water resources in each region has achieved relatively high efficiency.The rank order of water resources ecological footprint per GDP of ten thousand yuan is the southern of Shaanxi > Central Shaanxi > the northern of Shaanxi.The water resource load index of Central Shaanxi and the northern of Shaanxi is far more than 10.0,while that of the southern of Shaanxi is only 1.6,so the southern of Shaanxi has great potential for water resources development, and the Central Shaanxi and northern of Shaanxi need to invoke external water resources to maintain sustainable development.Precipitation is the main source of water resources in Shaanxi Province, so it is necessary to fully understand the distribution of water resources in various regions.Through improving economic structure and utilizing modern technology, water resources was developed and utilized continuously and efficiently, so as to benefit the sustainable development of social economy in Shaanxi Province.
