对1959-2000年广西春播期(2～4月)及各月降水进行EOF分解，分析了其空间分布型态及气候变化规律。结果表明：广西春播期降水及各月降水全区一致性偏多（少）是主要分布型态；2、3月降水呈增加趋势，由少雨向多雨转变，4月降水呈减少趋势，由多雨向少雨转变，二者有反相的特点；春播期及各月降水均存在准2a振荡，分月降水还具有45a左右的长周期变化；90年代后期，广西春播期降水进入一个相对少雨期。

The precipitation of Guangxi during spring sowing (Feb. ～ April) and in each month from 1959 to 2000 is decomposed by way of EOF to analyze its spatial distribution conformation and the climatic variation law. The results shows that the commonly more (less) precipitation during spring sowing and in each month is the main spatial distribution conformation. Precipitation in Feb. and in March tends to increase, and that in April tends to decrease on the contrary. Quasi-2-year oscillation exists in the precipitation in each month and during spring sowing, and precipitation in each month complies with a long periodically changing law of about 45 years. In the late 1990s, precipitation in spring sowing of Guangxi enters its cycle of less raining.
