Abstract  

The concept of water footprint introduced a novel thought on studying the sustainable utilization of water resources. The concept widens both the denotation and connotation of the traditional water resources evaluation system. In this paper, the CLIMWAT database and CROPWAT software, which were recommended by FAO, were used to calculate the crop water footprint in Jiuquan, Wuwei, Lanzhou, Pingliang and Tianshui of Gansu Province; and to construct the crop planting structure on the basis of rational utilization of water resources; to advocate the fully utilization of the green water resources; to minimize the negative environmental impacts of the blue water resources over-usage, the environmental deteriorations include the declination of groundwater level, soil salinization, water erosion and soil degradation. The results thus provide a new approach to study the environmental protection, water conservation and efficiency improvement, and the development of regional special agricultural industries.

Key words:  water footprint      crop      structure optimization
