利用1961—2010年黑龙江省62个气象站资料，基于5—9月平均气温和水稻冷害等级行业标准，利用累积距平和小波分析等方法分析水稻延迟型轻度、中度和严重冷害的空间分布特征及时间变化规律，以期为黑龙江省水稻延迟型冷害的研究提供参考。结果表明：1961—2010年黑龙江省水稻延迟型冷害主要集中发生在黑河、齐齐哈尔、哈尔滨东部、牡丹江西部和三江平原东部地区，其存在明显的阶段性变化，1994年后转入新的较少发生阶段，2000年后黑龙江省水稻延迟型冷害发生明显减少。黑龙江省水稻延迟型轻度冷害和中度冷害存在21 a和9 a左右的变化周期，水稻延迟型严重冷害存在21 a左右的变化周期。

Based on the mean air temperature data at 62 weather stations of Heilongjiang province from May to September during 1961-2010 and a standard on cool injury of rice(CIR),spatial and temporal distribution of de-layed CIR in mild,moderate and serious grades was analyzed using methods of an accumulated anomaly and a wavelet analysis in order to provide references for prevention of CIR.The results indicate that delayed cool injury of rice occurs mainly in Heihe,Qiqihaer,eastern Harbin,western Mudanjiang and eastern Sanjiang plain.There is a significantly variation for delayed CIR during 1961-2010 in Heilongjiang province.The CIR has a turning point in 1994 and seldom appears after 1994.The CIR decreases significantly after 2000.The cycles of delayed CIR are 21 years and 9 years for mild and middle grades respectively,while it is 2 1 years for serious grade.
