[Method] The temperature and precipitation in Zhucheng City from 1961 to 2010 were chosen to analyze its annual and seasonal changes based on linear trend estimation method. [ Result]The average temperature in recent 50 years rose at a speed of 0.383 ℃/10 a. The mean temperature in each season increased. As the temperature increase span in winter 〉 autumn 〉 spring 〉 summer, the mean precipitation in recent 50 years de- creased at a speed of 18.7 mm/10 a, increased in spring and winter but decreased in summer and autumn. Temperature reduced most distinctly in summer at a speed of 20.9 mm/10 a. The abnormal temperature reduction happened only once in Zhucheng in recent 50 years. Abnormal high temperature happened in seven years, after 1990s. In recent 50 years, only six years had abnormal precipitation and the annual total precipitation decreased, which indicated that the spatial distribution of precipitation was uneven. [ Conclusionl The study provided reference for the increasing accuracy of temperature and of precipitation report.展开更多
