基于GIS的中国地震危险性模式研究

Research on China earthquake hazard model based on GIS

从与历史地震数据的时间衔接考虑,合理选择初始地震危险性模式。借鉴美国地震危险性图编制的思路,并基于GIS的思想和技术,使用历史地震数对初始模式进行多次叠加改造,获得当今中国地震危险性模式。与实际地震灾害的对照结果,验证了该方法的有效性。可见,基于GIS的中国地震危险性模式研究具有一定的现实意义。

First, the initial Chinese earthquake hazard model was selected reasonably with the consideration of no time-gap between the different researches. Then, using the historical earthquake data and GIS, the current Chinese earthquake hazard model was constructed based on the initial model under the guidance of the theory of the United States National Earthquake Hazard Map. The effectiveness of the research was verified through comparison with actual earthquakes and finally, its significance was discussed.
