Based on the data of 18 cities in Henan Province from 2006 to 2015 , the water footprint(WF) of winter wheat and summer maize were calculated and the compositions were analyzed. And spatial auto-correlation analysis was used to analyze the temporal and spatial differences. The results showed as follows:①In terms of interannual variability, the WF of wheat showed a decreasing trend over time, among which Zhengzhou, Kaifeng, and Xinyang City had a maximum drop. However, the WF of summer maize production was irregularly distributed, which fluctuated greatly with the interannual precipitation.②In the spatial distribution characteristics, the high-value cities and the low-value cities of the winter wheat formed a significant agglomeration zone. The summer maize was characterized by more atypical cities, and aggregation was weaker than winter wheat.③In terms of water consumption composition of crop production, the ratio of winter wheat blue water footprint to production water footprint was higher than that of summer maize, showing a distribution pattern of north high and low south. In summer maize, the ratio of green water footprint to production water footprint was higher than that of winter wheat. It showed the different effects of water resources with uneven spatial and temporal distribution. And effective use of water resources for the main source of water for agricultural production should be strengthened.
