921大地震時中長期避難所與避難圈關係之調查研究

Research of the Relation between the Mid-term and Long-term Shelters and Evacuation Circulation on 921 Earthquake Disaster

1999年9月21日凌晨1時47分，台灣地區中部地區發生芮氏7.3級的大地震，災區的居民於受到地震災後，短時間內即須立即進行避難行為，從避難行動的推移，避難至附近較安全之公共設施，因此短時間內即產生有多量的臨時性避難所因應而生且後來衍生成中、長期臨時避難所，多數災民需暫時生活於其中的情形。本研究依據921大地震的規模，地震發生時避難者數量的推移、避難的行動特性，從實際調查結果，推演因受災區之特性影響避難者的行動特性等要因，在城、鎮、鄉、村等為單位的範圍地域，分析避難圈及中、長期避難所所呈現範圍及距離的關係，以建立大規模地震後居民避難逃生可及性的本土性資料，並依據避難逃生可及性的資料來建構適於本土性的避難圈範圍。

In Taiwan, an earthquake measuring 7.3 on the Ritcher scale occurred at l:47a.m. on September 21st, 1999. As soon as thee earthquake took place, the victims evacuate to the shelters in nearby safe public facilities. Therefore, a great deal of temporary shelters were established and later turned to be mid-term and long-term temporary shelters in which most victims live. Based on the scale of the September 21st, earthquake, the movement of the earthquake evacuees number, the tendency of the evacuees action, and the result of our on-site studies, we derived the causes that affected evacuees action in connection with the characteristics of the disaster area. Within the broad scope of cities, towns, countries, and villages, we analyzed the relation between the evacuation shelter circle and the mid-term and long-term shelters in the aspect of area and distance in order to acquire the domestic data of the evacuees extensibility after a large scale earthquake. According to the data, we intend to construct the scope of an evacuation shelter circle applicable for various domestic regions.
