摘要

2009年莫拉克颱風挾帶的巨大雨量造成台灣颱風史上最嚴重的災情，經過「莫拉克颱風災後重建推動委員會」的調查及統計，經濟總損失近新台幣2仟億元。然而由於莫拉克颱風為大規模的複合型災害，損失調查及評估的工作相當耗時費力，亦難對於災後復原工作提供即時的助益。故本文依據過去文獻研究及各部會歷年的災損調查成果，利用地理資訊系統發展各類淹水災害之快速損失計算模組，命名為「臺灣颱洪災損評估系統（簡稱TLAS Taiwan）」。此系統之建置對於災前的工程效益分析、風險評估，甚至是災後的損失計算等均有很大的助益，可作為國內各項防減災工作之重要評估工具。

Typhoon Morako 2009 caused the most serious damage in the historical typhoon event in Taiwan. The total economic loss was nearly NT 200 billion after one and half year survey by central government. But due to the severe disaster consequence, all kind of past-disaster recovery works had been started after just one month of the disaster, including recovery budgets and human resources. Meanwhile, the national wide loss survey of typhoon Morako become too late to be consulted by the recovery needs. Therefore, the efficiency of loss assessment plays a very important role.This paper utilizes all kinds of loss researches and empirical survey data in Taiwan, mainly including land loss, household loss, agricultural loss, industry and commerce loss, transportation and hydraulic use, and combine the technology of geographic information system, to built a calculated system, named Taiwan Typhoon Loss Assessment System, is called TLAS Taiwan.This automatically evaluating system not only can estimate loss quickly after disaster impact, and if the numerical scheme can simulate flood with mitigation measures, this method can further be used to obtain the financial gain or loss of that mitigation measures. Therefore, TLAS Taiwan can be used in any real engineering application so that there will be a standard or reference value associated with future natural hazard.
