The invention provides a regional lightning disaster risk evaluation method. The method is characterized by comprising the following steps of: (a), determining regional lightning disaster risk evaluation index systems U; (b), making danger level standards V for each evaluation index system; (c), calculating the weight coefficient W of each index by quoting an analytic hierarchy process; (d), calculating the membership degree of each quantitative index by quoting a membership degree function; (e), performing fuzzy comprehensive evaluation and calculating a correlation matrix; and (f) determining a risk level and a risk source and proposing lightning protective measures. The method is wide in application range, and meets the lightning risk evaluation in different industries such as flammables and explosives, railways, large-scale bridges and travels, and different types of buildings (structures). Various types of regional lightning risks are subjected to qualitative and quantitative comprehensive analysis by adopting a reasonable hierarchical comprehensive analysis method, so that the problem that influencing factors at each level are difficult to quantify is effectively solved.
