水稻生育中后期至收获阶段的连阴雨是影响其生长和晾晒的限制环境,研究连阴雨保险纯费率,对于降低农业气象灾害风险具有重要意义。本研究利用黔东南州16个县(市)1980-2020年水稻单产数据及气象资料,构建水稻连阴雨减产模型,基于拟合优度检验法,从6种分布模型中筛选各县(市)最优模型估算连阴雨灾害概率,结合连阴雨概率及减产率厘定保险纯费率。结果表明:黔东南州水稻连阴雨综合指数与减产率呈显著的线性关系,线性表达式为Yr=6.66CRI+4.12,连阴雨综合指数越大,水稻减产率越高。连阴雨发生概率随灾害程度加重而降低,各县(市)有30%~50%的概率发生轻度连阴雨,中度和重度连阴雨概率则分别为10%~30%、0~3%;海拔较高的麻江、黄平发生中度、重度连阴雨的概率较其余地区偏高。16个县(市)水稻连阴雨保险纯费率分别在7.38%~10.47%,西北部麻江、黄平两个县保险纯费率较高,达9.5%以上。
