Spatial Correlation Analysis of Geological Disaster and Geological Background in Liaoning Region

Abstract:

Liaoning Province is located in the southern part of northeast China,and within two first degree tectonic units,that is,Sino-Korean quasi-platform and Tianshan-Xingmeng geosynclinals fold system,it has complex geological environment,strong natural variability and frequent geological disasters. Taking GIS as a platform,selecting the factors of the stratigraphic,magmatic,tectonic,seismic and geological hazard,and using empirical weighting method,the paper analyzed the spatial relationship of geological disaster and geological background and acquired that Liaohe Group and Triassic is the major geological disaster strata and magmatic rock area is the more developed area of geological disaster,and disaster points mainlydeveloped in the Triassic of the Mesozoic.
