Abstract: The paper collected and compiled the different reverse results of crust structure in Fujian-Taiwan region by using artificial earthquake sounding, arrival time of natural earthquakes and Bouger gravity anomaly as well as seismic-geological data. Through analysis and comparison of these different models, the integrated 1-D average model of crust velocity structure in Fujian-Taiwan region was given and provided reverse research of 2-D or 3-D crust fine structure in the region with an appropriate 1-D crust model.

Key words: Fujian-Taiwan region, Crust velocity structure, 1-D preliminary model, Bouger gravity anomaly, Crust thickness
