Abstract:
Water is viewed as one of the most importantnatual resources, and it is also the essential factors to ensure food security and ecological security However, impacted by the rapid economic development and human activities, water scarcity has been a serious problem all over the world Therefore, it is urgent to quantitify the water use conditions to improve water resource protection Virtual water refers to the amount of water that is needed in the production process of goods and services, and it is a term that links water, food and trade Virtual water has been proven to be a very useful instrument to relieve the pressure in water shortage countries or regions by importing waterintensive products from those whose water resource is abundant Based on the powerful idea of virtual water and ecological footprint, the concept of water footprint is introduced in 2002 A water footprint measures the total water consumed by a nation, business or individual by calculating the total water used during the production of goods and services Virtual water and water footprint have become a hot spot in the field of water resource research Based on the data of Anhui statistical yearbook of 2011 and the concept of virtual water and water footprint, Anhuis water footprint and water resources sustainability were calculated and assessed The results show that the water footprint, the per capita water footprint and the per capita water availability of Anhui Province in 2010 were estimated to be 72 898 million m3[DK]·yr-1, 1 06779 m3[DK]·cap-1[DK]·yr-1, 63144 m3[DK]·cap-1[DK]·yr-1, respectively These indicate that the water consumption apparently exceeded that of water availability, and such a water footprint pattern is not sustainable Agricultural production was the largest water consumer, accounting for 9549% of the water footprint The remaining 451% was for the industrial, domestic and ecological environment sectors In addition, Anhuis 10 000 yuan water footprint is ralatively high, which is mainly due to a high dependence on irrigation for agricultural production These findings indicate a low efficiency of water resourceutilizing in Anhui Province Therefore, we need to optimize the crop planting pattern or to adjust the industrial structure to achieve more proper sustainable water use in Anhui Province This paper provided a scientific method to the water use and water resources management in Anhui Province
