摘要
选取年雷击大地密度、产值密度和人口密度3个因子作为评判指标,利用模糊综合评判法对厦门市6个区的雷电灾害风险进行了评估。结果显示:厦门市各区雷电灾害风险受地闪频次、经济发展和人口密度分布不均等因素的影响,思明区为高风险区,翔安区为低风险区,其余4个区为中等风险区。该划分为厦门市防雷部门针对本地实际情况制定科学、合理、经济的防雷设计方案提供了更为细致的参考。
The lightning disaster risk of the six regions in Xiamen city are evaluated using fuzzy comprehensive evaluation method with the densities of earth-stroked lightning, output value, and population as three evaluation indices. The lightning disaster risks in different regions of Xiamen city show that the Siming district, Xiang＇an district, and the other four districts belong to high risk area, low risk area, and medium risk areas, respectively, due to the discrepancies of ground flash, economy, and population. It is a more detailed reference to help the Xiamen lightning protection department to make scientific, appropriate, and economic lightning protection programs for the local situations.
