:利用泾河流域周边14个气象站点1957~2002年逐日温度、器皿蒸发数据,分析了近45 a来气温、器皿蒸发量的时空变化特征。Mann - Kendall统计检验结果表明:泾河流域气温变化趋势与同期我国气温变化趋势基本一致,年均温存在显著变暖的总趋势,增温率为0. 29 ℃/10 a。流域北部气候变暖趋势高于流域南部,变暖的季节主要是秋冬季节。年器皿蒸发量呈逐渐减少的趋势,倾向率为- 39. 3 mm /10 a,在空间上变率表现为流域南部、北部减少趋势明显,中部变化趋势不明显。

Using the monthly temperature and pan evaporation record from 14 meteorological stations in the J inghe River basin from1957 to 2002, the basic spatial distribution and temporal trend of temperature and pan evaporation were analyzed with the methods of climate tendency ratio andMann - Kendall statistic test. The results show that the temperature in the studied area increases and accordsbasically with that all over the country in the past 45 years, and the temperature tendency ratio is 0. 29 ℃/10 a. The temperature in2crease ismost significant in winter, then in autumn, and the temperature increases gradually from the northwest to the southeast part of the basin and obvious especially in north part of the area. In contrast, the pan evaporation decreases in the temporal dimension and the tendency ratio is - 39. 3 mm /10 a. The spatial distribution of long - term trend shows a decrease tendency in the south and the northpart of the basin, but it isn’t obvious in themiddle part. The evaporation change in the basin needs to take some other factors into con2sideration and the main cause for the change of evaporation will be further investigated in the further study.

Key words: J inghe River basin, temperature, pan evaporation, temporal and spatial features, trend analysis
