By analyzing the environmental temperature data of Zhengzhou, the seasonal distribution of the environmental temperature and the effects of different surface environment conditions on the temperature are revealed.The feature of heat island intensity of Zhengzhou varies with time and space is also discussed. The results show that the urban construction scale and the specific surface physical feature of the city have obviously affected the environment temperature distribution in time and space. The urban environmental temperature is higher than that in the suburb. The annual and seasonal variation of heat island intensity of Zhengzhou is coincident with the cities in North China. Heat island intensity in winter is also higher than that in summer.
