摘要
利用内蒙古自治区1960—2010年逐月降水量、稳定通过10℃积温、无霜期日数、春季大风日数等气象资料,以及1∶100万土壤类型资料,从水分指标、热量指标、大风指标和土壤资源4个方面,利用GIS插值、重分类、叠加分析等功能,结合内蒙古地区玉米耕作制度和作物种类特征,将内蒙古玉米气候区划分为3个等级,重点对7个适宜种植玉米的区域进行了气候特征和玉米品种的描述。
By using of monthly meteorological data of precipitation,≥10 ℃accumulated temperature,frost-free period days,spring winds days from 1960 to 2010 and 1 to 1 000 000 soil type data in Inner Mongolia, we selected division index from moisture, heat, wind, and soil resources, and then divided the corn climate into three level by using of GIS functions such as interpolation,classification and superposition analysis, which have considered the corn cropping system and crop species characteristics, the seven area suitable for planting corn about climate characteristics and corn varieties.
