Abstract: The data used in this study were collected from weather observation stations located in the rural area, around where nearly 50 years less changes in surroundings. The accumulated trends of temperature variation in the western Liaoning province was investigated by the serial correlation and climate tendency rate to provide literature for the research on the change and characteristics of climate, as well as the evaluation of the ecological environment in rural area. The results showed that increase range of the mean temperature in the rural area is found less than that of circumjacent cities. The mean temperature and the mean maximum and minimum temperatures increased considerably. The mean temperature increase remarkably and the series was correlated to the mean maximum temperature series significantly. Significant increase of the mean minimum temperature was not observed. The temperature increase was found in all of four seasons, and it is obvious in spring and autumn and especially in winter. The change of mean minimum temperature was not significant in the four seasons. The increase range of the temperature in the circumjacent cities is 2.6 times higher than that in rural area. Main change of the daily temperature occurred depends on maximum temperature, but did not increase significantly with daily minimum temperature. This analysis was conducted based on original data from the weather observation stations.
