摘要 采用气候统计学方法,对邢台地区1961~2010年初、终霜日及无霜期气候特征进行了分析。结果表明,初霜日平均值为10月22日,时间序列绝对变率为4.68 d,线性趋势为0.76 d/10 a,呈逐渐推迟趋势;终霜日平均值为3月27日,时间序列绝对变率为8.35 d,线性趋势为-0.29 d/10 a,呈逐渐提前趋势;而无霜期平均值为209 d,绝对变率为8.12 d,线性趋势为1.10 d/10 a,呈平稳增长趋势。初霜日、终霜日及无霜期的稳定变化趋势,对于霜冻预报具有重要的参考价值和指导作用。 Climatological statistics method was adopted to analyze climate characteristics of first and latest frost days as well as frostless period in Xingtai regions during 1961-2010.The results indicated that the average value of first frost day was October 22 and the absolute variability of time series was 4.68 days,the linear trend was 0.76 d/10 a,thus,the first frost day showed the delaying trend;for latest frost days,the average value was March 27 and the absolute variability of time series was 8.35 days,the linear trend was-0.29 d/10 a,thus,the latest frost days showed advanced trend;for frostless period,the average value was 209 d and the absolute variability of time series was 8.12 days,the linear trend was 1.10 d/10 a,thus,the frostless period showed a steady growth trend;in addition,the stable variation trend of first and latest frost days as well as frostless period had significant reference value and guidance function for frost forecast.
