| dc.description.abstract | In recent years, due to the impact of global climate change, the frequency and intensity of extreme rainfalls and the typhoons increased greatly. Consequently slopeland disasters increased significantly after 2000. The vulnerability assessment, the delineation of vulnerability potential hazard maps and risk management, are important issues to protect human lives and property as the adaption policies for climate change.
Vulnerability, including exposure, sensitivity and the correction factor of adaptability, is the measure of the fragility of risk element under certain level of hazard. Resilience can be used as a vulnerability reduction factor post the disaster event. This study provides a quantitative method of vulnerability assessment for debris flow events, which not only considers the relationship between disaster intensity and loss curve, but also takes the spatial distribution and the characteristics of risk elements into account. According to the vulnerability components , we can propose improvement strategy and reduce vulnerability by adaptions which change the values of vulnerability factors. Finally, a case of the Nansalu, quantifying the vulnerability of buildings and people that caused by the invasive Typhoon Morakot on August 9 2009. The coping strategies to reduce vulnerability are also proposed. | en_US |
