摘要: 依据科尔沁沙地最典型地区-奈曼旗气象站1981-2010年逐月、逐旬降水资料,结合不同的气候特征,采用正交多项式回归法及相关分析法等数理统计方法,利用GIS技术分析了奈曼旗干旱对玉米产量的影响。结果表明,干旱对奈曼旗玉米产量的影响较其他气象因子大。

Abstract: Based on the precipitation data collected from 1981 to 2010 by meteorological station of Naiman County which was one of the most typical regions of Horqin sand land, the influence of drought on the corn yield reduction was analyzed by using orthogonal polynomial regression and correlation analysis method and GIS technology combining with different climatic characteristics.
