Abstract. The North China Plain (NCP) is serious lack of fresh water resources, while crop production consumed about 75 % of the region's water. To estimate water consumption of different crops and crop structures in the NCP, the Hebei southern plain (HSP) was selected as a study area because it is a typical region of groundwater overdraft in the NCP. In this study, water footprint (WF) was being used which was consisted of green, blue and grey components. The results showed: (1) the WF of the main crops production was about 51.0 km3 in 2012 and winter wheat, vegetables and summer maize were in the top three leading among the main crops in the HSP, while the water footprint intensity (WFI) of cotton was the largest and vegetables were the smallest; (2) winter wheat and vegetables consumed the main groundwater and their blue water footprint (WFblue) accounted for 66.0 % of the total WFblue in the HSP; (3) the crop structure scenarios analysis indicated that, with about 20 % of arable land cultivating winter wheat-summer maize in rotation, 40 % spring maize, 10 % vegetables and 10 % fruiters can promote the sustainable utilization of groundwater resources, at the same time can ensure sufficient supply of food, vegetables and fruits in the HSP.
