构建东北地区水稻开花期冷涡型光-温-水复合逆境产量损失评估等级指标,对阐明中高纬度地区冷涡型复合灾害叠加效应对水稻产量损失的影响机制具有参考意义,可为保障中国优质粳稻安全生产、区域减灾增效提供气象支撑。本研究利用生育期资料、气象资料、产量资料,界定并构建寒稻开花期冷涡型光-温-水复合逆境发生指数,采用BP神经网络法分层次分析致灾因子与产量结构的关系度、不同产量结构与产量的关系度,解析复合致灾过程,基于K-均值聚类方法及历史典型灾害年确定灾害临界值和等级,建立冷涡型光-温-水复合逆境产量损失评估指标及评估模型,并分析东北三省水稻开花期低温多雨寡照的时空分布特征。结果表明:研究区水稻开花期轻度、中度、重度冷涡型光-温-水复合逆境产量损失评估指标临界阈值分别为[0,0.21]、[0.21,0.32]、[0.32,0.64],产量损失率分别为[0,0.03]、[0.03,0.08]、[0.08,0.096]。基于1961—2020年随机11年总计751条样本的验证结果显示,利用本研究构建复合指数计算的减产等级与实际减产等级一致的站点比例为63.7%,各年均超过58.0%;一致或相差1级的站点比例为88.3%,各年均超过85.0%。该指标能够很好地评估冷涡型复合灾害造成的东北地区水稻产量损失率。
