摘要:: 根据粤东地区各县（区）的1989—2017年台风资料，以自然灾害系统理论为指导，利用GIS技术方法对粤东地区台风灾害危险性、承灾体的脆弱性、减灾防灾能力进行了初步评估，并在此基础上建立了台风灾害综合风险评估体系，获得粤东地区各县（区）台风灾害风险分布。结果表明：（1）粤东西南地区是台风灾害发生的高频区，也是危险性高值区，这一地区应提高台风警预性；（2）承灾体脆弱性高值区集中分布在榕城、潮阳、金平、龙湖、澄海、南澳，这些地区应该优化土地利用结构调整、提高人口素质和台风灾害的防御能力，从而降低承灾体的脆弱性；（3）陆河的防灾减灾能力最低，该县应加大对医疗卫生投入和提高事业保障能力。根据评估结果，台风灾害风险高值区主要在陆河、陆丰、惠来、南澳，这些地区应成为防御台风灾害的重点区。

Abstract:: According to typhoon data of counties and districts in East Guangdong in the period 1989-2017, under the guidance of the typhoon disaster system theory, risk of typhoon disaster, exposed vulnerability of carrier and ability of disaster prevention and reduction in east Guangdong region were assessed by using GIS technology. Based on those assessments, the typhoon disaster risk assessment system of east Guangdong was established, and maps of typhoon risk distribution were made. The results showed that the southwest of east Guangdong was the high frequency of typhoon disaster area or regions with high-value of hazard, so typhoon forecast should be improved in this area. The regions with high-value vulnerability of hazard-affected body were found in Rongcheng, Chaoyang, Jinping, Chenghai, Nan’ao. It is necessary to adjust land use structure, and improve population quality and the ability to defense typhoon to reduce the vulnerability of hazard-affected body. Luhe had the lowest ability for disaster prevention and mitigation. It is necessary to increase investment in health care and improve the ability of undertaking support. Based on the assessment results, regions with high-value of risk were centralized in Luhe, Lufeng, Huilai, Nanao, and those areas should be considered as the important districts of typhoon disaster prevention.
