基于ArcGIS的地震站网规划研究OA

In order to further encrypt and optimize the construction of seismic stations,Anhui Province plans to build new seismic stations on the basis of the existing seismic observation network and closely combined with the earthquake situation in Anhui Province.According to the principle of taking into account the improvement of early warning ability of the whole province and appropriate encryption in key areas,this study takes the slope data,traffic road data,historical earthquake data,existing station distribution data,Tanlu fault zone data and population density data of Anhui Province as the influencing factors of seismic station location.The weight of each influencing factor is determined by the analytic hierarchy process.With the advantage of spatial analysis in ArcGIS,the suitable area for site selection is analyzed,the site selection model of Anhui Seismic Network is established,to optimize the scheme and obtain the optimal site area,so as to ensure the distribution rationality of Anhui seismic network planning.
