摘要: 2009 年莫拉克颱風造成台灣中南部地區嚴重受災,災害型態由洪水或崩塌等單一形式災害,轉變為崩塌、洪水、堰塞湖之複合型災害,本分析藉著「全流域管理」的精神、「尊重大自然」的思維及「國土復育」的理念,使集水區有專業知識以整體治理。 本研究主要針對降雨因子造成的「超大洪水量」、「崩塌災害」及「土石流災情」,進行探討分析,以有效減輕災害之發生。並以中部災區為例進行集水區歷史災害調查分析演算。直接探討莫拉克颱風災害前後崩塌與延時雨量的關係;分析水土保持現行策略對土砂整治率、水土保持構造物、區域性避難規劃及聚落區之合適性。 在無法預知之極端氣候發生機率增加清況下,策略目標應以聚落安全為核心,評估各類災害的影響範圍;除加強軟硬體減災措施外,更應著重於土石流防災監測及預報等非工程措施。
2009 Typhoon Morakot resulted in serious disasters in central and southern Taiwan. The type of disaster is changed from single flooding or landslide to compound disasters, which includes avalanches, floods and barrier lakes. This analysis is based on the spirit of 'Total Catchment Management (TCM)', the thought of 'Respect to Nature' and the idea of 'Land Restoration', so that the watershed area could be comprehensively governed by professional knowledge. This study focuses on the rainfall factors of 'Tremendous Floods,' 'Collapse Hazard' and 'Mudslide', to take an effective approach to reduce the occurrence frequency of disasters. Taking Taiwan Central Disaster Area as an example to investigate, analyze and to perform calculation of historical watershed disaster data. Directly investigate the relationship between the collapse and rainfall before and after Typhoon Morakot. Analyze the appropriateness of the current policy to the 'Ratio of Sediment, 'Soil and Water Conservation Structures' and 'Regional Refuge Planning and Settlement District of Soil and Water Conservation.' Under the increasingly possibility of unpredictable extreme weather, the core of the strategic objectives should be the 'Settlement Security' to evaluate all influence of disasters. In addition to strengthening the hardware and software mitigation measures and also emphasis on the debris flow monitoring and forecasting.
