According to data of water demand from 2003 to 2012,the paper analyzed the water utilization structure characteristics and evolution trend in Haihe river basin by use of information entropy, direction coefficient and Mann-Kendall test. The results showed that balanced degree of structure in the basin has rising trend which is not obvious.The stability of water utilization system gradually strengthens. With the operation of ecological water recharge projects in Haihe river basin,the water utilization structure mainly develop towards the ecological water use.
