The temperature sequence data from 1953 to 2005 of Benxi are used to analyze the basic climatic characteristics, interannual variation, period variation, coldwarm variation, variation trend, etc. The results indicate that the annual mean temperature distribution was not consistent with seasonal distributions. The annual mean air temperature was the lowest in the 1950s, but the low est growingseason temperature was in the 1970s. The lowest temperature in spring was consistent with the annual mean air mperature. The lowest temperatures insummer and in autumn were found in the 1970s, and that in winter was in the 1960s. The total temperature tended to go up gradually.
