Water footprint is a new method for the evaluation of utilizing and consuming patterns of regional water resources. Based on water footprint theory, Jinan citys crop water supply amount, import and export of virtual water amount and value of water footprint were calculated in this paper. The conditions of agricultural water resource and its security condition from 1997 to 2013 were analyzed. The results showed that footprint of green water, blue water and grey water in Jinan's water footprint increased year by year. In water footprint for agricultural production, wheat, corn and vegetables played the supporting roles for Jinan's agriculture. In the aspect of agricultural water security, water resources average deficiency degree was 536%, pressure index was up to 789%, agricultural per capita water footprint was 717.9 m3. Overall, Jinan's agricultural water pressure and water shortage are serious which need people to improve the regulation and storage capacity of local water resources , to optimize the planting structure and import types of virtual water, and to strength water-saving projects.
