中文摘要 | 隨著經濟發展、新市鎮密集開發等社會經濟方面之提昇,使得災害的損失風險及影響相對提高,在災害管理及減災方面,損失推估及危險度分析為相當重要的課題。然而區域災害損失的評估,涉及許多時間及空間上的資料,因此本研究中乃應用空間資料以更準確地掌握天然災害在時空上的變異性,同時以臺北縣汐止市住宅區的淹水損失分析作為研討對象。研究中考量了土地使用及建築物類型之災害潛勢差異,同時以社會經濟資料,包括每戶居住人口、建物特性、一般家庭內裝部分的裝潢及基本配備等資料建立了淹水深度損失曲線,再應用淹水深度損失曲線法,將住宅區的淹水損失以一般家庭、機電設備、以及汽機車損失三方面來推估。此外由於住宅區特性將隨著時間而變動,故本研究中以人口普查資料中建物的分佈情形及各類型建物的基本特性,建立一套映射的機制,以掌握住宅區面積隨時間變化的成長及窄縮情形。 |
英文摘要 | The risk of damage from natural calamities increases in regions where the population is dense and the economy grows rapidly. Damage assessment and risk analysis are important issues in damage management and mitigation. Regional damage assessment processes are involved huge amount of data most of which are spatially and temporally distributed. Using flooding damage assessment for residential area as a pilot study, this paper focuses on the use of available spatial data to accurately capture the spatial characteristics of damage in natural calamities. The inundation region is subdivided into smaller areas based on land use and building types. Flooding damage is estimated based on three categories: the common indoor assets, public utilities, and mobiles. A depth-damage curve is constructed from social-economic data such as persons per household, building characteristics, living style, and common indoor decorations and appliances. A mapping scheme is built for estimation of buildings and residential area distributions using census data to accommodate temporal change. The Shi-Ju City in Great Taipei Area was used as an example in this study. |
