摘　　要：为促进农业灾害预防和减灾工作的开展,利用Mann-kendall检验和Morlet小波法研究了黑龙江省1980-2015年农业低温冷害和风雹受灾率的时间变化特征。结果表明:在1980-2015年,低温冷害受灾率呈下降趋势,风雹灾害受灾率呈上升趋势,但二者均未通过0.1水平上的显著性检验。通过Morlet小波分析可知,低温冷害和风雹受灾率的变化主周期分别为7和19a,通过变化周期小波系数拟合可知,二者受灾率在2017-2019年处于正相位。In order to promote the prevention and mitigation of agricultural disasters, we studied temporal change characteristics of agrometeorological chilling injury disasters and hail tornadoe disasters which affect-ed agricultural productivity in Heilongjiang Province from 1980 to 2015 by Mann-kendall and Morlet wavelet methods. The results showed that the disaster rates of chilling injuries were in the trend of subsiding and the disaster rates of hails &. tornadoes increased from 1980 to 2015 by Mann-Kendall analysis. The change trends of the two agrometeorological disaster rates did not pass the significant test at 0. 1 level. The results of Morlet wavelet variance of agrometeorological disasters in Heilongjiang Province during 1980-2015 analysis showed that disaster rate of chilling injuries and hails & tornadoes changed periodically at 7 a and 19 a time scale.re-spectively. The disaster rate of chilling injuries and hails tornadoes over the period 2017-2019 would remain in positive phase.
