- Abstract:
-
From the perspective of virtual water of crops, the amount of virtual water per unit weight of major crops and the total amount of virtual water of major crops were calculated and analyzed based on Penman formula combining CROPWAT software from 2000 to 2012 in Xinjiang. The results showed that the virtual water of major crops was ranked from high to low as cotton, wheat, corn, potato, vegetable; the amount of virtual water per unit weight of major crops in Xinjiang decreased, but the total amount of virtual water generally showed the upward trend. The former was closely related with each region of Xinjiang adopting water-saving irrigation technology and increased yield per unit area, and the later was mainly due to the expansion of planting area and the great improvement of yield. From the perspective of virtual water, we can adjust the farming policy and crop planting structure, and provide decision for implement of water resource management, having the important significance for ecological protection in Xinjiang.
