Using statistical data，the dynamic changes of nitrogen，phosphorus and potassium nutrient application in Hebei province were analyzed from 2000 to 2016. With the test results from the wheat fertilization project of “NPK-3414-experiments" (n = 3358)，a further analysis was conducted to achieve the appropriate amount of nitrogen，phosphorus and potassium nutrients and the potential of fertilizer reduction in wheat. The results showed that the maximum amount of nutrients consumption in Hebei province was 335.6×104 t which occurred in 2014，after then showed a downward trend. The investigation data showed that the current application rates of N，P2O5 and K2O of wheat were 223.9，151.2 and 59.8 kg·hm-2 in Hebei province. In addition，the optimal N，P2O5 and K2O rates of wheat in Hebei province should be 155.9，117.2 and 92.5 kg·hm-2，respectively，through a linear with plateau model analysis. There had a huge fertilizer reduction potential of 12.58×104 t from the current famers practice to the optimal fertilizer application rate. Among which，nitrogen fertilizer could be reduced by 14.55×104 t (accounting for 28.4% of total nitrogen consumption of wheat)；phosphorus fertilizer could be reduced by 4.94×104 t (accounting for 28.4% of total phosphorus fertilizer consumption of wheat)；potassium consumption needed to increase by 6.91×104 t. The maximum fertilizer reduction potential city was Shijiazhuang city，while the minimum was Xingtai city.
