摘 要:利用26个气象观测站1971-2000年标准气候统计资料和1∶25万地理信息资料,采用多元回归方法建立了兴安盟马铃薯种植气候区划因子与地理信息的推算模型,确定了兴安盟地区马铃薯种植综合气候区划指标,并依托GIS技术划分了马铃薯适宜、次适宜及不适宜种植地区。结果表明,内蒙古兴安盟西北部气候冷凉,昼夜温差大,湿润度较好,是兴安盟优质马铃薯种薯基地,应逐步扩大种植面积;而兴安盟东南部由于7月份温度过高,降水量偏少,加上昼夜温差相对其它地区小,不利于马铃薯高产优质,应逐步减少马铃薯种植面积;兴安盟中部偏东南地区由于热量资源居中,降水量相对较多,为马铃薯次适宜种植地区。Using standard climate statistics from 26 meteorological stations during 1971~2000 and 1∶25 million geographic information,the authors established a regression model between climatic regionalization factors of potato planting area and geographic information,identified the indicators of comprehensive climatic regionalization factors in Xing'an League,and also divided the Xing'an League into appropriate,second appropriate and inappropriate areas for potato planting by GIS technology.The result shows that north-west of Xing'an League in Inner Mongolia is a high quality potato-producing base because of its cool climate,big day-night temperature difference and good wetting degree.Potato planting area should be gradually expanded in this region.The climate of south Xing'an League is disadvantageous for high quality and high-yield potato planting because of its too high temperature in July,little precipitation and small day-night temperature difference.Potato planting area should be gradually reduced in this region.The central south of Xing'an League is second appropriate for potato planting because of its mid heat resources and relatively higher precipitation.The divisional results have an important reference value to the rational use of climate situation,farming structural adjustment,and the improvement of the quality and yield of potato production.
