| 摘 要： | 利用1961-2010年吉林省21个气象站5-9月逐日气温、降水量、日照时数资料,按照低温冷害气候学标准,分别对吉林省5-9月各月低温冷害发生规律、发生类型、时空分布进行了系统分析.结果表明:1961-2010年吉林省5-9月各月的低温冷害发生频次没有出现突变,都在减少,但显著性水平各不相同.各月低温冷害发生频次具有3～5 a的短周期特征,5月、6月、7月、9月中发生的低温冷害有10～15 a的中周期,长周期表现不明显,受局部地貌等因素影响,吉林省5-9月各月的低温冷害发生频次在5月表现为东西多、中部少的特点；6月、7月则呈现全面多发的态势；8月呈现中东部多、西部少的特点；9月则呈现东西多、中部少的特点.吉林省低温冷害型多表现出低温多雨和低温少日照的特征. |
| 关 键 词： | 低温冷害 发生频次 发生类型 时空特征 吉林省 5-9月 |

| Abstract: | This research are analyzed by using the daily temperature,precipitation,sunshine time in May—September of 21 weather stations to analysis the chilling damage occurrence,type of chilling damage,spatio-temporal characteristic in Jilin Province for the period 1961—2010.The result shows:the frequency of chilling damage haven’t mutation in recent 50 years,there is t a decreasing trend,but significantly different.Chilling damage show characteristics of 3~5 years short-cycle in recent 50 years,chilling damage that occurred in May,June,July,September show characteristics of 10~15 years middle-cycle,long-cycle characteristic is not obvious.Chilly damage show different regularity by local landscape and other factors in May—September;Chilling damage shows characteristic of drought,but less sunshine in September. |
| Keywords: | frequency of chilling damage incidence type spatio-temporal characteristic Jilin Province May—September |
