摘要
气温的变化影响着一个地区各个方面的发展。本文利用1991～2010年间逐日气温及同时期冬小麦单产资料,通过对比商丘市1991～2010年气温变化及同时期冬小麦单产的变化,研究商丘市近20年间年平均气温变化与冬小麦单产的关系,为调整农业生产措施提供基础资料。研究结果表明,1991～2010年这20年间,商丘市年均温呈现波动上升的趋势,同时期小麦产量也呈波动上升趋势。20世纪90年代初期气温变化不明显,此时小麦产量也无明显的变化,但自1994年后气温波动上升较为明显,同时期冬小麦的产量也呈现出相同的变化趋势。因此,气温的上升在一定程度上促进商丘市冬小麦产量的增长。
The changes in temperature affect all aspects of social development in one region.In this study,it was used the data of the daily air temperature and winter wheat yield at the same time in1991~2010to analysis the change of temperature and winter wheat yield in ShangQiu from1991~2010and study the relationshop between the temperature change and winter wheat yield in ShangQiu recent20years,in order to provice basic information for the adjustment of agricultural production.The results shown that the annual mean temperature showed flucturating upward trend,with periods of wheat yield also showed a rising trend of fluctuation from1991to2010in ShangQiu.The changes of temperature and the winter wheat yield were not obvious at the beginning of1990s,while the temperature increased more obviously since1994and the yield of winter wheat also showed the same change trend.Therefore,the rise in temperature can promote the growth of winter wheat yield to a certain extent.
