摘要
灾害损失率计算是农作物保险费率确定的基础。研究设计以大系统理论的“分解-协调”技术为指导,对河北省冬小麦、玉米、棉花气象受灾程度分级和灾害损失率分区。多年平均灾害损失率分区为基本控制层,采用类型区划分体系,且以单元归并法划分分区;多年平均灾害损失率为基础控制层,采用多年平均灾害损失率指标计算,反映灾害损失率的宏观分布规律和微观空间分布差异,使区域费率确定更加准确、合理。
Calamity loss rate is the base for calculation of insurance premium. The technique of 'resolve-coordinate'of large system theory was used in classification of meteorological calamity degree of winter wheat,maize and cotton and regional division of calamity loss rate in Hebei Province. For the purposes of rationally and correctly determining regional calamity loss rate, regional division of the perennial average calamity loss rate was used as the baste control layer and the classification system of regional type and unit merging was used to conduct the regional division; while the perennial average calamity loss rate was utiliged as the calculation index to reflect the macro- and micro-space distribution of calamity loss.
