| 摘 要： | 基于江苏适应气候变化农业开发项目区1961-2008年逐日气温和降水资料,统计分析了48a来苏北项目区气温、降水的变化特征,以及在此背景下界限温度的积温、无霜期长短、四季时间和参考蒸散的变化特征.结果表明,48a来苏北≥0℃、≤ 10℃积温量和积温日数显著增加,无霜期延长了15-30d;春季时间延长最明显,夏季次之,冬...

| Abstract: | Based on the 1961—2008 daily temperature and precipitation data of northern Jiangsu Province,the variations of temperature,precipitation,accumulative temperature,frost-free period,the four seasons period and referenced evapotranspiration were analyzed in this paper,the results suggested that over the past 48 years,the amounts and days of accumulative temperatures with T≥0 ℃ and ≥10 ℃ increased remarkably,the frost-free period prolonged by 15—30 d.For the four seasons,the length of spring prolonged longest,and summer was the second,however,the length of winter shortened most obviously,and followed by that of autumn.The referenced evapotranspiration decreased slightly in spring and summer,and increased slightly in autumn and winter. |
