摘要
利用 1991～ 2 0 0 0年内蒙古地区气温、降水及主要粮食作物产量数据 ,分别给出热量和降水量的利用效率 ,并根据综合指数对光、热、降水资源利用效率作出综合评价 ,得出了内蒙古主要粮食作物气候资源综合利用效率的区域分布 :粮食、玉米和小麦除黄灌区外东部平均综合利用效率高于中西部 ,谷子则中西部高于东部。
In this paper, an aggregative index has been defined in order to descr ibe the comprehensive features of agroclimatic resources efficiency in Inner Mon golia. Based on the calculation of meteorological and grain yield data of the 10 years (1991-2000), we analyzed heat and rainfall utilization efficiency distrib ution of main grain crops at 29 represent stations. The result shows that the ag gregative indexes of grain crops, spring wheat and maize are higher in eastern p art than that in central western region except the irrigation areas of Yellow R iver in Inner Mongolia, while the index of millet in the central western part i s higher than that in the eastern part.
