Research on lightning disaster prevention in rural areas of Anhui Province:taking Ma'anshan City as an example
Based on the lightning positioning monitoring data of Anhui province from 2010 to 2020 and the statistical data of lightning disasters in Ma'anshan City from 1998 to 2022,a lightning density(intensity)calculation model was used to analyze the frequency,density(intensity)and the spatiotemporal distribution characteristics of lightning disasters.The research shows that lightning activity is the main disaster-causing factors of lightning disaster.The density of ground flash is between 0.04～1.50 times/(km2·a-1)and the intensity of ground flash is between 0.50～0.71 kA/(m2·a-1)in Ma'anshan,the possibility of lightning disaster in areas with large density(intensity)of ground flash is also high;the comprehensive lightning protection measures such as the renovation of lightning protection system inside and outside rural buildings(structure),lightning area interception and electrical equipment surge protection can prevent and reduce the losses caused by lightning disasters.The research results aim to provide decision-making reference for rural disaster prevention and mitigation management.
