中國大陸位於世界兩大地震帶，環太平洋與歐亞之間受洋板塊、印度和菲律賓海的擠壓，地震十分頻繁由於發生具有不確定性以及具有瞬間造成重大災害的能力，因此本文研究希望藉由地震 危害度分析來瞭解未來地震可能帶的影響 。 本文將介紹大陸震源區的三級劃分，逐步探討中國與陸地震區劃圖的改進與變化，也收集了各分動衰減式以及危害度析的計算流程。最後提到建置推測事件資料庫，以福建為例，資料庫內包含了對於福建省地區產生重大災害之震事件，再利用此 資料進行地震危害度分析，以供模擬福建地區475年迴歸期下，各處之最大地表加速度，並繪出等加速度圖。;Mainland China locates between the two largest seismic belts, the circum-Pacific seismic belt and the circum-Indian seismic belt. Squeezed by the Pacific plate, the Indian plate and the Philippine plate, earthquakes happen frequently in China. Due to lacking of capability to predict earthquake, this research is to assess the potential seismic demand of earthquake. The thesis introduces the three layer of classification for the seismic source and further discuss the relation between seismic source classification and different earthquake area, as well as collecting the seismic motion attenuation relations of each zone. This study presents the process of construction a stochastic event database which is used to analyze seismic hazard. In the end of this study it hopes to measure the demand of earthquake in future by seismic hazard analysis. In order to construct a database in this thesis, it uses GIS program to separate occurrence rate in area source and considers characteristic earthquake model in line source. The database includes all of the earthquake events associated with Fujian. Finally, we use this database to construct a contour of peak ground acceleration in Fujian with 10% probability of exceedance in 50 years (475-years return period).
