Chinese Abstract

摘 要 臺灣常受到颱風、地震等天然災害的影響,造成崩塌、土石流等土砂災害,近年又受到氣候變遷影響,使得暴雨事件發生頻繁且強度增加,流域脆弱度提高,災害發生的機率相對越高,政府為了保護人民生命、財產的安全,對各流域進行了整治工程。如何在治理與經濟獲得最大效益,本研究選出脆弱度因子,瞭解各流域之脆弱情形,排出優先治理順序,以供未來相關單位進行流域整治之參考。 本研究對臺灣主要的五大流域之脆弱度進行研究,分別為淡水河流域、大甲溪流域、濁水溪流域、曾文溪流域及高屏溪流域,並透過發放效度問卷,從水文、地文、人文、氣候變遷4個層級構面,豐枯比、洪峰流量、懸浮固體、總磷、總氮、植生覆蓋率、崩塌地面積比例、人口密度、都市化程度、豐枯比變化率、洪峰流量變化率、懸浮固體變化率、總磷變化率、總氮變化率14 項評估因子進行分析,再利用專家問卷並採用多評準決策分析法,進行因子權重之計算,最後做出排名,在無氣候變遷下,最需優先整治的流域為高屏溪流域,有氣候變遷下,最需優先整治的流域則為濁水溪流域。

English Abstract

Abstract Taiwan is often affected by typhoons, earthquakes and other natural disasters, resulting in collapse, landslides and other disasters in recent years as a result of the impact of climate change. Hence, so frequent storm events have increased in strength. The need to improve watershed vulnerability is relatively higher, while there is the higher probability of disasters. The government needs to protect people's lives and property with each watershed remediation project. In order to attain the most benefits and economic governance, this study has selected vulnerability factors, examined the fragile situation of each watershed and prioritized the treatment sequence and related units for future reference watershed renovation. This study examines the vulnerability of Taiwan's five major watersheds including Tamsui, Tachia, Jhuoshuei, Tsengwen and Kaoping, through validation through questionnaires that include examining hydrology, physiographics, humanities, climate change, four levels dimensions, and 14 assessment factor analysis, Recycling experts use MCDA, calculate weight factors, and finally set ranking, in the absence of climate change. The most in need of remediation priority is Kaoping, The most in need of remediation priority watersheds is Jhuoshuei.
