| 摘 要： | 根据广东省近10年来的雷电灾害统计资料和近35年来的雷暴日观测统计资料，提炼出雷击密度、雷电灾害频度、经济损失模数、生命易损模数作为雷灾易损性评价指标。在详细分析了广东省各地市的自然环境、经济状况和各地区雷灾损失情况，对广东省各地市面对雷电灾害的脆弱性和易损性进行了综合评估，初步形成了各地易损性结构和广东省雷灾易损度区划。提出雷电灾害区域易损性分析、评估的模式，为区域防御雷电灾害、减低雷电损失的规划提供科学依据。

| Abstract: | With 10 years'statistical data and the date of thunderstorm-day in 35 years of Lightning disaster in Guangdong province, lightning strike density, lightning disaster frequency, economic loss rate and population exposed to lightning disaster are selected as vulnerability evaluation indexes. Based on detailed valuation of district and county in Guangdong, a comprehensive evaluation of the weakness and vulnerability of lightning district and country in Guangdong is made and the vulnerability degree of lightning district is calculated. And also vulnerability zoning is made in Guangdong by means of GIS. Accordingly, a model for regional vulnerability analysis and evaluation of lightning disaster is developed, which provides scientific basis for the planning of regional lightning disaster prevention and reduction. |
