Water resources ecological footprint model offers a new method for evaluating the sustainable utilization of water resources. This study firstly analyzed the water resources ecological footprint and the ecological carrying capacity of water resources in the years from 2005 to 2014. And then used LMDI method to analyze that impact the water resources ecological footprint. The result show that The total water resources ecological footprint increased and the contribution size could be ranked as agricultural water＞industrial water＞domestic water＞ecological water during 2005-2014. The water resources ecological footprint of ten thousand Yuan GDP is decreased year by year, which indicates that the water resources efficiency is increasing. But there is different levels of ecological deficit in the past 10 years, the water resources utilization prospect is still not optimistic. The contribution order of four index factorizes for water ecological footprint is as follows: water footprint structure effect ＞economic effect＞population effect＞ technical effect, and the economic effect has a tendency to catch up the structure effect.
