| 摘 要： | 根据天山北坡经济带6个气象站点的气温及降水资料,利用线性趋势函数及滑动平均法分析了该区域近42a的气候变化。结果表明:近42a来天山北坡经济带年平均气温、平均日最高气温、平均日最低气温及春、夏、秋、冬季气温均呈上升趋势,其中90年代是气温上升最显著时期。平均日最低气温上升的幅度远大于平均日最高气温的上升幅度,并且冬季增温明显。年平均降水量及春、夏、秋、冬季降水自80年代后出现增加趋势。除春季外,其余各季降水均有上升趋势,从线性拟合看,夏季降水量上升趋势最显著。

| Abstract: | According to the data of temperature and precipitation at six meteorological stations in the Northern Slope Economic Zone of Tianshan Mountain since recent 42 years,the climate changes were analyzed by using the Linear fitting and Moving-average method.The results showed that the mean annual,maximum,minimum and four seasonal temperatures in the Northern Slope Economic Zone have been in an increasing trend since recent 42 years,and the increase of temperatures was more significant in 90s.Among them,this tendency was more significant in winter and the increase of the mean minimum temperature was much higher than the maximum one.The annual mean and seasonal precipitation have increased since 80s.Except spring,the precipitations were in an increasing trend.According to the linear fitting,the change of precipitation was increased in summer. |
