Using the observation data of temperature and precipitation from 1981 to 2010 in Shidao area, the characteristics of climate change in Shidao area in the past 30 years and their impacts on agricultural production were analyzed by statistical analysis methods .The results showed that the annual average temperature of Shidao area was increased by 0.205 ℃/10 a in recent 30 years, except for the autumn, the average temperature in spring, summer and winter were increased.Annual precipitation slowly increased at a rate of 33.4 mm/10 a, the precipitation in spring, summer and autumn showed a slowly increasing trend , while winter precipitation showed a slowly decreasing trend .Climate warming had both advantages and disadvantages to agricultural production, with increased incidence of catastrophic weather events and extreme precipitation events , droughts and floods may tend to increase, affecting agriculture more heavily.%利用石岛地区1981—2010年气温与降水观测资料,采用统计分析方法,对近30年石岛地区的气候变化特征及其对农业生产的影响进行分析.结果表明,近30年石岛地区年平均气温以0.205℃/10 a的速度上升,除秋季外,春、夏、冬各季平均气温均呈上升趋势;年降水量以33.4 mm/10 a的速度缓慢增加,春、夏、秋季降水量均呈缓慢上升趋势,冬季降水量呈缓慢减少趋势.气候变暖对农业生产有利有弊,灾害性天气和极端降水事件将有所增加,干旱和洪涝可能趋于增加,对农业生产影响较大.
