台灣在歷經了921大地震之前，人民對於防救災觀念始終一知半解，政府有關單位對於防救災系統之建構之投入也有其限制。然而，近年來的大地震所帶來的巨大損害重新喚醒了民眾及政府部門對於防救災觀念之重視與體認，也突顯出防救災計畫的重要性。都市為人口與經濟活動高度聚集地區，因此受到地震災害影響的層面遠比其他非都市地區來的嚴重，而地震所帶來直接與間接之傷害充分暴露台灣都市防災空間系統之弱點與不足。因此透過文獻回顧、現況調查與專家問卷調查等方法，建構一套適宜之地域危險度評估模式，以檢測都市空間之安全性，並作為事前防災計畫擬定之基礎，為本研究之動機。
其次，本研究流程是將先透過文獻回顧及實地調查法之方式去建構災害危險度之評估因子及項目，做為都市地域危險度評估模式之基礎，並藉由專家問卷及分析階層程序法，來求取評估因子間相對權重與重要性；此外，本研究選定苗栗市作為實證地區並藉由評點法及GIS空間分析功能之運用，對苗栗市進行測定評估，並檢討該市防災空間系統。本研究從評估結果去了解目前實質空間之防災機能，並同時檢討都市防災空間系統，提出相關對策與建議來加強防救災之事前規劃，以期創造一個人民安全無虞之防耐震安全都市空間。 / Before the 921 Earthquake happened, the people in Taiwan had ignored the concept of disaster prevention and rescue for a long time. Nevertheless, the recent huge damages by earthquake re-awakened the emphasis. The Urban is a human and economic activities intensive region, therefore the damaged degree by earthquake in urban regions is far serious than in the non-urban region.
The motive of study is to build a district-based assessment of vulnerability. The process of study has some steps as follows. Firstly, the study chooses the factors and indicators. Secondly, the study uses expert questionnaire and AHP to determine the relative importance of each factor.
Furthermore, the study chooses the Miaoli City as the example. Eventually, according to the assessment results, the study provides some suggestions to improve the planning of disaster prevention and rescue system in urban spaces.
