| 摘 要： | 利用渭北旱塬麟游县近46年来的气温、降水量资料对其气候变化特征进行了分析。得出:麟游县46年来气温呈波动上升趋势,年平均气温的倾向率为0.02℃/10a;从季节性变化来看,春季增温明显,特别是2000年以后。麟游县46年来降水量以0.709 mm/10a的趋势增加,而增加的降水量主要来自冬季降水量的增加。年总降水量与年平均气温以及春季、夏季、秋季降水量与相应季节气温间均呈负相关,冬季降水量与气温间呈正相关。

| Abstract: | Based on the observed data of precipitation and temperature from 1960 to 2005 in Linyou county,the climate changeable characteristics were analyzed.The results showed that the temperature of Linyou county had an increasing trend with fluctuation,especially in spring.The mean annual temperature in Linyou county was increased by 0.02 ℃ per 10 years.The increase of temperature mainly took place after 2000.The mean annual precipitation was increased by 0.709 mm per 10 years,and the increase of the precipitation was mainly due to the rising of the precipitation in winter.The test with SPSS software revealed that there was negative correlation between mean annual precipitation and mean annual temperature,as well as between the rainfall in spring(or summer or autumn) and the temperature in the corresponding season.Winter precipitation was positively correlated with winter temperature. |
