基于信息扩散理论的安徽省农业风雹灾害风险评估
Risk Assessment of Agricultural Wind and Hail Disasters in Anhui Province Based on Information Diffusion Theory
摘要
Abstract
The paper aims to evaluate the crop loss caused by wind and hail disasters in Anhui Province. The authors carried out a risk assessment of agricultural wind and hail disasters in nearly 22 years (1991-2012) with an risk assessment model based on the information diffusion theory. The results showed that: in Anhui Province, agricultural disaster area of wind and hail was relatively small, the affected index was under 10%, the wind and hail disaster risk level was low and the risk probability was once in 156 years. The affected index of the wind and hail disaster in Anhui Province was generally no more than 8%, and under this index, the risk probability was about once in 10000 years. The wind and hail disaster risk probability of every city in Anhui Province decreased with the increasing of the damage degree.关键词
