作者以大系统理论的“分解－协调”技术为指导进行成果体系设计，在功能上由两个控制层组成：灾害损失率分区为基本控制层，多年平均损失率为辅助控制层。在成果应用中，以分区为基本依据，以多年平均损失率为参考依据，共同确定保险费率。多年平均损失率分区采用类型区划分体系，它既能反映灾害损失率宏观分布规律，又能刻划灾害损失率较微观的空间分布差异，使区域费率确定更加准确、合理
The author uses “decomposition-coordination” technology of large-scale system theory as the guide to design the result system. It is composed of two control layers: the disaster loss rate is divided into the basic control layer and the average loss rate for many years is the auxiliary control layer. In the application of the results, the district is taken as the basic basis and the average annual loss rate is used as a reference basis to jointly determine the premium rate. The multi-year average loss rate zoning is based on the type area division system. It not only reflects the macroscopic distribution law of disaster loss rate, but also characterizes the spatial distribution differences of disaster loss rate and microscopic degree so as to make the determination of regional rates more accurate and reasonable
