全球水稻生产数据分析表明,1961年至2018年全球水稻面积、单产和总产年均增幅分别为0.67%、1.65%和2.33%,受多种因素制约,近年单产和面积增长幅度变小。水稻在亚洲、非洲、美洲、欧洲和大洋洲均有种植,其中,亚洲水稻种植面积占比为87.9%,非洲占7.7%、美洲占4.0%,欧洲和大洋洲不到0.5%。近10年与上世纪60年代相比,全球水稻种植面积和总产区域间分布已发生变化,非洲水稻面积增长,亚洲水稻面积下降。1961年至2018年全球水稻总产增长因子分析表明,总产增长的60%~70%来自单产的提高,各洲水稻总产增长贡献因子存在较大差异。

The average annual growth rate of rice area, yield per unit area and total yield per unit area increased by 0.67%, 1.65% and 2.33%, respectively, according to the analysis of global rice production from 1961 to 2018. Rice is cultivated in the continents of Asia, Africa, America, Europe and Oceania. Among the rice planting areas in the world, Asia accounts for 87.9%, Africa accounts for 7.7%, America accounts for 4.0%, and Europe and Oceania account for less than 0.5%. Compared with the 1960S, the global rice planting area and the distribution of total rice production in the near 10 years have changed. The harvest area of rice in Africa has increased, and the harvest area of rice in Asia has decreased. Global rice yield growth factor analysis showed that 60% to 70% of the total yield growth was contributed from the increase of yield per unit area. The contribution factors of total rice production growth varied greatly among different continents.
