| 摘 要： | 赤峰、通辽地区是内蒙古玉米作物的主要产区,文章统计并分析了1979—2008年该地区玉米生长期的降水和气温的变化,计算了玉米生长期的干燥度指数,并利用干燥度指数分析了温湿条件对玉米气象单产的影响,结果显示：玉米生长期的温湿条件是影响单产波动的主因,当温湿条件有利时,玉米将增产,否则会减产。

| Abstract: | Chifeng and Tongliao Region is a major maize product area in Inner Mongolia.In this study,variations of the precipitations and temperatures of maize growing season in this region during the last 30 years（1979-2008） were statistically analyzed.In addition,a kind of aridity index was also calculated which was utilized to analysis the effects of temperature-moisture conditions of the growing season on maize yields per unit area.The result indicates that the maize yield will increase if the temperature-moisture conditions are benefit for the growing,and if not vise verse. |
