摘　　要：四川省自然灾害类型多、发生频率高、活动强度大,研究以四川省5种主要自然灾害为评价对象,合理选取评价指标,确定指标权重,计算自然灾害综合评价值,得到全省以及181个县级市主要自然灾害危险性等级,并分析了全省主要自然灾害区划分异特征、主要灾害源地,为区域减灾防灾、区域发展规划提供了数据基础及理论依据。Natural hazards in Sichuan Province are characterized by multiple types, high frequency and high intensity. This paper took five types of major natural hazards as objects of study, adopted proper indices and index weight, calculated the synthetic values and acquired the risk grades of major natural hazards in 181 counties and districts in Sichuan Province. Further analysis was made of the space differentiation and sources of major hazards, thus providing a solid basis for regional disaster prevention and economic development.
