摘要
以湖北省国家级气象站点1959年~2008年逐日气温和降水量数据为依据,运用累积距平、滑动平均、Mann-Kendall检测法以及空间插值法等方法分析湖北省温度与降水时空变化特征,分析影响和制约变化的因素.结果表明,湖北省近50a来,年平均气温总体呈上升趋势,气温与降雨具有明显的代际时间梯度与空间变异性,站点间气温与降雨变化率具有显著的区域差异性.
In the present work,the daily temperature and precipitation data collected by the national meteorological stations in Hubei from 1959 to 2008were taken as the basis.The spatial-temporal variation characteristics as well as the factors and constraints on temperature and precipitations in Hubei Province were analyzed with methods including cumulative anomaly,moving average,Mann-Kendall detection and sptial interpolation.The results show that in the recent 50 years,Hubei＇s annual average temperature is rising.The temperature and rainfall significantly vary in intergenerational gradient and space.Besides,the change rate of temperature and precipitation displayed significant regional difference among the sites.
