摘要 利用河南省114个气象站点1971-2000年气候资料和台站地理信息,采用梯度距离平方反比法分别对棉花各发育期的平均气温、降水总量和日照时数等气候资料进行了网格推算。根据棉花生产的气候适宜度函数和不同生育阶段的参数,计算了棉花不同生育期内光、温、水的气候适宜度,采用相对权重法计算了综合适宜度。根据河南省棉花的农业气候区划指标,将全省划分为最适宜区、适宜区和次适宜区3个分区。区划结果显示河南省棉花最适宜种植区在豫北、豫东和豫西南等地,中南部是棉花种植适宜区,豫西丘陵、豫北山区及淮河以南地区是棉花种植的次适宜区。最后对各区域的特点及建议进行了评述。 Based on the geographic information and climate data from 114 meteorological stations in Henan province during 1971-2000,the climatic elements in grids of different growth phases of cotton,including average temperature,total precipitation and sunshine hours,were established by using gradient plus inverse distance squared technology.According to the climatic suitability models and the parameters in different stages of cotton growth,the climate suitability values of precipitation,temperature and sunshine hours in different growth phases were calculated.The comprehensive impact of three factors was evaluated by the relative weight method.Three regions for cotton planning in Henan province were divided by using agricultural climatic division factors,which were the most suitable region,the suitable region and the sub-suitable region.The most suitable region included north,east and south-west of Henan province,the suitable region included central-southern part,and the sub-suitable region included the west hilly region,the north mountain area and the south region of Huaihe River.
