额尔齐斯河流域降水与气温变化分析
nalysis on the Change of Precipitation and Air Temperature in Irtysh Basin
选取额尔齐斯河流域塞米巴拉金斯克（1926-1995）、鄂木斯克（1928-1995）、托博尔斯克（1931-1995）3个代表站的实测月降水资料及逐年气温资料, 利用距平分析法、11a滑动平均法、坎德尔（Mann - Kendall）方法以及时间序列的小波分析方法对流域上的降水量、气温的变化趋势以及降水量的突变及周期特征进行了分析。结果表明：额尔齐斯河流域年降水量在整个研究时段内呈现增加的趋势，同时具有一定的突变和周期特征。该流域年平均气温也呈现一定的上升趋势，且鄂木斯克站气温倾向率较大。
By using anomaly analytical method、11a moving average method、Mann - Kendall method and wavelet analysis along the time series to analyze the series of precipitation and air temperature, and study characteristic of abrupt change and periodicity of precipitation from 3 representative stations(Semipalatinsk(1926-1995) 、Omsk(1928-1995)、Tobolsk(1931-1995)) in Irtysh basin. The results revealed that precipitation of this basin in the whole have a increased current in this period, at the same time have a certain change and periodicity. The yearly air temperature of this period was in an ascending trend, and the climatic tendency of Omsk was comparatively high.
