This study presents a novel preparedness assessment method for assessing hazard mitigation and environmental planning of hillslope communities. A professional questionnaire was utilized to weight each indicator. Communities in Hsinchu, Taichung and Nantou counties with debris flow hazards were taken as study samples. Debris flow risk and landslide susceptibility for each community were determined using Geographic Information System (GIS) technology and logistic regression analysis. Thus, a novel risk assessment method for evaluating disaster resilience capacity of hillslope communities was established. This method was then applied to assess casualties caused by Typhoon Herb in 1996 and Typhoon Mindulle in 2004. Additionally, the analytical results generated by this assessment method were discussed with the aim of developing references for implementation of risk analysis, increasing the effectiveness of disaster mitigation, and reducing future loss of life and property.  相似文献   

Wave of peace? Tsunami disaster diplomacy in Aceh, Indonesia     

Jean-Christophe Gaillard  Elsa Clavé 《Geoforum》2008,39(1):511-526

This paper uses the disaster diplomacy framework to address the impact of the 26 December 2004 tsunami disaster on the decades-long conflict between the Free Aceh Movement (GAM) and the Government of Indonesia. This framework enables the identification of a micro-factors of great importance in securing momentum for the peace talks. These factors include informal networks being created, plus disaster relief and diplomacy occurring at multiple levels through multi-way processes and the position of GAM dedicated to reconstruction activities. This paper further shows that, in the case of Aceh, the disaster had a deep influence on the peace talks between GAM and the Indonesian government and on the eventual implementation of the peace agreement reached. However, the tsunami disaster should not be considered the sole vector of peace in Aceh, but as a powerful catalyst in diplomatic talks, since negotiation between both sides were ongoing before the disaster and were favoured by recent changes in the political environment. Twenty-eight months after the tsunami catastrophe, it is actually non-disaster and internal political factors which are likely to have a more significant impact on the long-term resolution of the Aceh conflict. One important outcome is that it appears that the slow, unequal and often poor reconstruction process is not hindering, or even threatening, the peace process because tsunami disaster related factors are less important for peace than non-tsunami disaster related factors, findings in line with previous disaster diplomacy case studies.  相似文献   

千里岩的气温变化特征及其与西北太平洋副热带高压的关系     

贾瑞丽  郭可彩 《海洋预报》1997,14(4):67-72

本文根据１９６０～１９９４年千里岩和青岛月平均气温资料，分析了千里岩与青岛３５年来气温的年、季变化特征及差别，发现３５年来，千里岩和青岛的年、季平均气温均呈变暖趋势，但千里岩增温幅度较青岛小。从分析中发现，与气温变暖趋势相对应，西北太平洋副热带高压（以下简称副高）面积、强度指数的年、季变化也呈明显的增强、增大趋势。且年平均气温与冬季副高面积指数相关最显著。最后依此关系建立回归方程，并预测了１９９６年千里岩年平均气温的变化趋势。  相似文献

灾害生态学——生态学的一个重要发展方向   总被引：4，自引：0，他引：4  

章家恩 《地球科学进展》2002,17(3):452-456

对灾害生态学有关的基本概念与主要研究内容进行了探讨。认为灾害实际上是一种异常的生态学现象与过程，因此需要从生态学的角度加以研究，特别是要对灾害系统的发生成因、类型、时空分布、发展、危害、预测、控制和灾后恢复等的全过程生态学现象和规律以及相关技术进行研究。同时指出，当今，应围绕重大的全球性环境灾害问题，对其发生与发展的生态学机制与生态学后果，以及减轻、防范这些灾害的关键技术开展研究。  相似文献   

Impact of Southern Oscillation on the Frequency of Monsoon Depressions in the Bay of Bengal     

Singh  O. P.  Ali Khan  Tariq Masood  Rahman  Md. Sazedur 《Natural Hazards》2002,25(2):101-115

The impact of Southern Oscillation on thecyclogenesis over the Bay of Bengal duringthe summer monsoon has been investigated.The analysis of correlation coefficients(CCs) between the frequency of monsoondepressions and the Southern OscillationIndex (SOI) reveals that more depressionsform during July and August of El Niñoyears. Due to this, the seasonal frequencyof monsoon depressions remains little higherduring El Niño epochs even though thecorrelations for June and September are notsignificant. The CCs for July and August aresignificant at the 99% level.The El Niño-Southern Oscillation (ENSO)is known to affect Indian MonsoonRainfall (IMR) adversely. The enhancedcyclogenesis over the Bay of Bengal duringJuly and August is an impact of ENSO whichneeds to be examined closely. Increasedcyclogenesis over the Bay of Bengal may bereducing the deficiency in IMR duringEl Niño years by producing more rainfallover the eastern parts of India duringJuly and August. Thus there is a considerablespatial variation in the impact of ENSOon the monsoon rainfall over India and El Niñoneed not necessarily imply a monsoonfailure everywhere in India.The area of formation of monsoon depressionsshifts eastward during El Niño years.Warmer sea surface temperature (SST) anomaliesprevail over northwest and adjoiningwestcentral Bay of Bengal during premonsoon andmonsoon seasons of El Niño years.May minus March SOI can provide useful predictionsof monsoon depression frequencyduring July and August.  相似文献
