摘要

政府每年均投入大量資源進行災後治理工作，對政府財政造成沉重負擔，因此，本文乃基於成本效益與災害風險理論，提出一山崩災害工程治理績效之評估模式，並以南投縣廬山溫泉區的山崩為研究案例，用以說明本文模式的程序及結果的合理性。本文模式提供一個量化的績效指標，方法程序包括山崩機率、災害損失、風險降低量及益本比的估算。經由本文的案例結果，顯示本文方法具可行性及合理性，並可對工程及非工程措施的績效加以評估，優於一般傳統的績效評估法，可供政府作為災害治理方案之決策參考。

Every year the government invests a lot of resource in the mitigation work against disaster which causes a heavy burden on the government finance. In this paper, a performance evaluation model for reducing landslide disasters is proposed by the theories of costbenefit analysis and disaster risk management. The case study of landslide disasters of the Lushan hot-spring district in Nantou County is described to present the practicable process and rational results of the proposed model. The proposed model quantifies a performance index including the calculation of landslide occurrence probability, loss, risk reduction and ratio of cost-benefit. The case results show that the practicability and rationality of the proposed model are better than the traditional performance evaluation method. The results can be a reference for making policy decision for the government.
