摘要:
以EM-DAT(OFDA/CRED 国际灾害数据库)为主要数据源,在分析洪涝灾害特征的基础上,探讨了亚太地区洪涝灾害发生的时空分布格局.研究结果表明:(1) 1990—2010年,亚太地区洪涝灾害呈明显上升趋势,每次洪涝灾害造成的死亡人口和经济损失也呈现上升趋势;(2) 在空间上,东南亚发生洪涝灾害的次数最多,南亚和东亚洪涝灾害造成的死亡人口最多,东亚地区洪涝灾害造成的受灾人口和经济损失最大;(3) 亚太地区41个典型国家中,中国和印度发生洪涝灾害的次数较多,但每次洪涝灾害造成经济损失最高的国家为朝鲜,造成死亡人口最多的国家为尼泊尔;(4) 近年来,亚太地区在防洪减灾能力方面有了比较明显的提升,但南亚地区和朝鲜、尼泊尔、中国、印度、日本、韩国等国家仍需全面提高防洪减灾能力,以减少洪涝灾害造成的人口死亡和经济损失.

Abstract:
Based on the EM-DAT (OFDA / CRED International Disaster Database), the characteristics of floods and their spatial and temporal characteristics in Asian-Pacific region were analyzed and discussed. The results show that (1) there is an obvious increasing trend of the floods from 1990 to 2010, and the average death and economic loss caused by floods are increasing in the Asia-Pacific region. (2) In spatial, the number of floods is the most in Southeast Asia, the death is the highest in South Asia and East Asia, while the affected people and economic loss is the highest in East Asia. (3) From the aspect of nation, the numbers of floods in China and India are more than other counties in Asia-Pacific region. However,the highest economic loss caused by flood disaster occured in North Korea,and the most death occured in Nepal. (4) Recent years, disaster reduction has been promoted greatly in this region but there is still a long way left for South Asia and other countries such as North Korea, Nepal, China, India, Japan and South Korea to enhance their capacity of disaster reduction in order to bring down the death and economic loss.
