摘  要：
利用鲁西平原8个气象站1961—2012年逐月平均气温,采用线性趋势、Mann-Kendall突变检验、小波分析等方法分析了鲁西平原气温的时空变化特征。结果表明:年平均气温呈现波动上升趋势,2001年以后通过显著性检验,温度上升趋势明显。除夏季气温呈现下降趋势以外其余各季节均为上升趋势。各季节小波分析中气温异常表现不明显;没有长时间的持续偏冷或者偏暖,小幅度的冷暖交替变化比较频繁,各季节的小波周期变化各不相同。空间分布中东阿气温最高,高唐最低。

摘  要：
Based on the relevant datas from monthly average temperature of 8 stations in Luxi plain during the period from 1961 to 2012,the methods of trend analysis,ann-Kendall test and wavelet analysis method were used to analyze the characteristics of temperature in Luxi plain.The results indicated that there was an obviously and volatility warming tendency of annual average temperature.The temperature passed significance test after 2001.The temperature of all seasons except summer had warming tend.The abnormal temperature of different seasons by wavelet analysis was nonsignificant;there was not long time continuous cold or warm,and small changes in temperature changes were frequent,the different seasons of wavelet cycles were different.The highest temperature country was Donge and the lowest temperature country was Gaotang.
