Abstract: The connotation of water resources value contains the scarcity of water resources, the property right of resources and working value. It should be evaluated by fuzzy mathematics since there are many uncertain factors affecting the water resources value. The water resources value in Zhengzhou City has been calculated by an established fuzzy mathematical model with evaluation factors such as water quality, water resources quantity, gross national product and population desity according to the real situation of Zhengzhou City. The result of water resources price in Zhengzhou is 2.11 yuan（￥）/m3. At present the average water price in the city is only 1.28 yuan（￥）/m3, which is low obviously. Therefore water price reform is necessary.

Key words: water resources value, fuzzy mathematics, water price
