摘要
运用统计学方法对河西走廊东部 196 1～ 2 0 0 0年日照、气温、降水、蒸发等气候资料进行统计分析得出 :4 0年来 ,气温呈持续升高趋势 ,进入 2 0世纪 90年代升温加速 ,冬季升温最为显著 ,春、秋季次之 ,夏季升温幅度最小。日照、降水呈增加趋势 ,蒸发呈减少趋势 ,但增减幅度均不大。同时分析了气候变化对河西走廊东部生态、农业的影响 ,提出了提高气候资源利用率的途径。
The statistical analysis of observed sunshine duration,air temperature,precipitation and evaporation in Wuwei,Gansu Province from 1961 to 2000 indicates that air temperature kept increasing during the previous 40 years,and the temperature increase speeded up in the 1990's,which was the most obvious in winter,less in spring and autumn,and the least obvious in summer. The sunshine and precipitation had an increasing trend,and evaporation had a decreasing trend. But the increasing rates were not big. The effects of climate variation on the ecology and agriculture in the eastern Hexi corridor were analyzed and some suggestions for utilizing climate resources are given.
