Abstract: Tangshan has become a typical heavy industry city since the earthquake. The observational and statistical data were applied to analyze the temperature, rainfall, character of the wind speed variation in the area of Tangshan during 1977-2006. The multiple regression method was used to analyze the impact of the urbanization on the average temperature. The results showed that: (1) the temperature factor was the most effected. The rainfall and the wind speed varied obviously without regularity. The annual temperature range was 0.51℃, the increasing rate was 0.17℃/10 a. However, the annual temperature range was 0.67℃ after 1990. (2) The temperature discrepancy was closely related to the cumulative areas of construction, the dissipation energy of the whole society and the current urban area, but not obviously related to the city’s population and the total value of industrial output. The situation was caused possibly by the differences of the economic structure, energy consumption and exhaust emission in different cities.
