[ Method] Using temperature from 1981 to 2010 in six national ground meteorological observation stations in Jinan, and based on linear evaluation method, temperature changes in Jinan in recent 30 years were discussed. [ Result] The mean annual temperature, mean annual highest temperature and mean annual lowest temperature were rising in recent 30 years. Mean annual lowest temperature was increasing and its tendency rate was 0.502 ℃/10 a, followed by mean annual temperature whose tendency rate was 0.288℃/10 a. Mean annual highest temperature increased most slowly and its tendency rate was 0.144 ℃/10 a. The mean annual lowest temperature rose most significantly in Zhangqiu and its tendency rate was 1. 347℃/10 a. This indicated that the rising mean annual temperature in Jinan was due to the mean annual lowest temperature. The contribution of Zhangqiu City to the temperature changes in the entire Jinan was the largest. For single station, mean annual temperature, mean annual highest temperature and mean annual lowest temperature, temperature rising tendency was small and its contribution was the smallest. [ Conclusion] The study provided theoretical basis for the observation, diagnosis, evaluation and decision-making of climate changes in Jinan.展开更多
