摘 要:基于中国1985—2015年的县域向日葵生产数据,分析了向日葵产量、面积和单产的时空动态变化特征,揭示了向日葵的重心迁移轨迹和贡献率变化,同时评估了全国各县向日葵生产优势度。1985—2015年,20%向日葵集中于内蒙古东部和中部;产量重心向西南方向迁移了1 065 km,面积重心向西南方向迁移1 116 km;中国向日葵生产主导因素为面积主导;中国向日葵生产规模优势区域主要分布在内蒙古、新疆。对向日葵产量影响最主要的因素是种植面积,在农业生产中向日葵病害的防治较为重要。Based on the data of counties sunflower production from 1985 to 2015 in China,the spatial and temporal changes of sunflower production,area and yield was analyzed to reveal the migration trajectory of sunflower gravity center and contribution rate of different factors in sunflower production changes,and to evaluate the sunflower production dominance in counties across the country.The results showed that from 1985 to 2015,20%of sunflowers were concentrated in the eastern and central parts of Inner Mongolia;The gravity center of production shifted to the southwest by 1 065 km,and the gravity center of area migrated to the southwest by 1 116 km;The dominant factor of sunflower production in China is area,and it was mainly distributed in Inner Mongolia and Xinjiang.The most important factor affecting sunflower production was the planting area,and the prevention and control of sunflower diseases in agricultural production was more important.
