| 运用数理统计方法对渭北旱塬5市19个代表性气象站点1970—2010年的气温及降水量气象要素进行了统计分析，研究了全球气候变化背景下渭北旱塬气候变化及气候生产力对其响应。结果表明：渭北旱塬年、季平均气温均呈明显上升趋势，春季和冬季的升温幅度较大；年、季降水总量呈下降趋势，其中春季及秋季的降水量呈下降趋势，而夏季及冬季的降水量呈上升趋势；气候生产力呈增加趋势，未来暖湿型气候对作物生产最为有利，气候生产力平均增加12.1%，“冷干型”气候对作物生产最为不利，气候生产力平均减少18.3%。 |
| 英文摘要: |
| The date collected by 19 meteorological stations located in five regions of the Weibei plateau and statistic methods were used to study the effects of the climate and climate productivity in Weibei plateau under global climate change. The results showed that, in Weibei plateau, the average annual and seasonal temperature tended clearly to rise and the temperature-increasing rate in spring and winter was higher than that in summer and autumn, while the annual rainfall and seasonal rainfall tended clearly to decrease, and the rainfall in spring and autumn tended to decrease and that in summer and winter tended to increase. The climate productivity tended to increase, and the “warm-et type” climate in the future was beneficial to crop production, under which the average climate productivity-ncreasing rate would be 12.1%, while the “cold-dry type” climate in the future was detrimental to crop production, under which the average climate productivity decreasing rate will be 18.3%. |
