以区域农业灾情形成机制为突破口，以山西省农业自然灾害数据库为依托，逐一分析山西省农业自然灾害系统诸子系统──孕灾环境、承灾体、致灾因子与灾情系统的特征值，并研究了各相关要素对区域农业灾情的贡献率。以此为根据，构造了描述自然灾害系统及其子系统的定量指标。从而系统分析了山西省农业自然灾害系统灾情形成机制。得出的主要结论是：可以利用计算机进行自然灾害信息管理；区域农业相对灾情与绝对灾情意义不同，必须将两指标同时作为系统特征指标；单一的自然灾害要素难以解释灾害形成机制，自然灾害子系统的综合指标可以更好地刻画自然灾害。
Taking the formation mechanism of regional agricultural disasters as the breakthrough point and the database of agricultural natural disasters in Shanxi Province as the base, this paper analyzes the system of natural disasters in agriculture in Shanxi Province systematically - the characteristics of pregnant disaster environment, disaster-bearing body, disaster-causing factor and disaster system, And studied the contribution rates of various related factors to the regional agricultural disasters. Based on this, quantitative indicators describing natural disaster systems and their subsystems are constructed. This paper systematically analyzes the formation mechanism of agricultural natural disaster in Shanxi Province. The main conclusions drawn are: Computer can be used to manage natural disasters; relative disasters of regional agriculture and absolute disasters have different meanings, and both indicators must be taken as systematic characteristic indicators at the same time; a single element of natural disasters is difficult to explain the mechanism of disasters, natural disasters Comprehensive indicators of the system can better characterize natural disasters.
