| 摘要: | 近年來因氣候變遷，各地天然災害的消息頻傳。在2004年的南亞海嘯使15萬人罹難，當我們剛把這段可怕的事實忘記，接下來的卻是令人更加震撼的是發生在2011年3月11日的日本海嘯。日本海嘯帶來的不但是人員傷亡或是經濟損失的問題，而是海嘯衍生出來的核災問題，故這次日本海嘯更令世界譁然，也使各國對於海嘯與核能的課題提高警覺。這些事件是台灣的最好的借鏡，也喚起台灣對於海嘯災害的危險意識。
理論上，本研究運用地理資訊系統(GIS)進行實驗，使用海嘯相關文獻所得到之知識，以及避難場所的基本規則轉化為本研究海嘯緊急避難場所之所需之規範，運用其理論在地理資訊系統(GIS)之實驗中。
主要步驟首先是收集相關得文獻以及基地調查，整理出適合的相關文獻。再把像資料匯入地理資訊系統(GIS)，歸納成數位資訊，以便日後資料查詢與修正。然後，透過地理資訊系統(GIS)以圖像的呈現，分析適當的避難場所以及避難路徑。最後，把分析出來的資料做檢討與評估，為宜蘭縣居民規劃最佳海嘯避難場所。
具體成果得到宜蘭縣土地和建築物海嘯各波高淹水面積，在海嘯波高0.3土地淹水面積約125公頃，同樣的建築物所淹水的面積約502公頃，接著再以波高最高的32公尺，其土地淹水面積約29,795公頃而建築物約1,949公頃；最高以及最低土地淹水相差是17,249公頃，建築物淹水面積相差約1,446公頃。透過這些得到數據繪製宜蘭縣的淹水區域分佈圖。另外再以宜蘭縣鄉鎮和村里在海嘯各波高，找出相對應的避難場所。再以時圈分析，並且評估其效能度。最後提供宜蘭縣海嘯災害避難場所作決策時應用與參考。
In recent years because of climate change, natural disasters all over the news keeps pouring in. In the 2004 South Asia tsunami that killed 150,000 people, when we just forget this terrible truth, next is even more shock occurred on March 11, 2011 Japan tsunami. Japan tsunami no casualties or economic losses caused by the problem, but a problem of deriving from nuclear disaster of the tsunami, the Japan tsunami shocked the world, enabling countries about tsunamis and nuclear issue alert. These events is Taiwan's best models, aroused Taiwan for tsunami disaster risk awareness.
In theory, this study used geographic information systems (GIS) experiment, using proceeds to tsunami-related literature of knowledge and shelter a basic rule to study the specifications required for the tsunami emergency shelters, use their theory in the geographic information system (GIS) of experiment.
Primary are to collect the relevant documents as well as base for enquiries, sorting out the appropriate literature. Divide data into geographic information systems (GIS), into digital information for future data query and modification. Then, through a geographic information system (GIS), image rendering, analysis appropriate for a place of refuge and shelter the path. Finally, the review and assessment of the data analysis, and planning the best tsunami shelters for Yilan County residents.
Specific results get Yilan County land and buildings tsunami the wave high flooded water area, in tsunami wave high 0.3 land flooded water area about 125 hectares, also of buildings by flooded water of area about 502 hectares, then again to wave high highest of 32 meters, its land flooded water area about 29,795 hectares and buildings about 1,949 hectares; highest and minimum land flooded water difference is 17,249 hectares, buildings flooded water area difference about 1,446 hectares. Through these data in Yilan County's flooded area map. In addition to Yilan County towns and villages in the tsunami wave height, find the corresponding places of refuge. When you come to circle analysis, and to assess its effectiveness. Providing tsunami disaster refuge in Yilan County last application and reference when making decisions. |
