Zusammenfassung:In this paper, the main factors controlling and influencing regional crustal stability as well as the coupling action of internal and external dynamic geology in Shenfu New Area were analyzed, using both previous findings and field survey results. Based on the GIS platform, the regional crustal stability assessment was carried out through the multi-factor weighted superposition analysis method. Twelve influencing factors were selected, including fault activity, seismicity, deep geophysical status, engineering rock group, topography and surface geological hazards. The regional crustal stability assessment model was established in terms of relevance and importance of the influencing factors, through which to quantitatively assess the regional crustal stability of Shenfu New Area. And the results show that Shenfu New Area is dominated by the stable and sub-stable areas covering 728.9 km2, accounting for 81.07% of the total area, which is conducive to the planning and construction in this area.
