基于中国南方早稻种植区10个省211个气象站点1951—2010年的逐日气象数据，分析了生育期尺度的气候适宜度时空分布特征。结果表明，南方早稻气候适宜度偏低，但基本上能满足早稻的生理需求，除云南省外，光照是限制南方早稻生长的关键气候因子，降水是限制云南省早稻生长的关键气候因子。1980年作为气候适宜度变化趋势的转折点，1951—1980年与1981—2010年2个时段内各气候因子适宜度及气象适宜度的变化趋势差异较大。

Based on the 1951-2010 daily meteorological data from 211 weather stations in the 10 provinces of southern China , this paper analyzed the space-time characteristics of climate suitability of early rice in the southern China. Results show that climate suitability can basically meet the physiological needs of southern early rice. Sunlight is the key climate factor affecting the growth of early rice in southern China except Yunnan province, and precipitation is the key climate factor affecting the growth of early rice in Yunnan province. The year of 1980 is the turning point of climate suitability change trend. The climate suitability tendency is different between the period 1951-1980 and 1981-2010.
