| Abstract: | Geological hazards are the serious natural disasters that harm the living of mankind Its distribution, occurrence and process are of spatial character, and the influencing factors of them having their own features and complexity GHMIAS--The Geological Hazards Map and Image Analytical System is a kind of applied geological information system (GIS) Besides the basic functions of GIS, such as input, management,display, processing and output, etc, this newly developed system has fairly abundant GIS functions for analyzing and modeling as well as unique spatial analysis model extension The authors made out a lot of analysis on the hazards distribution, occurrence mechanism, influencing factors, development trend in Beijing Tianjin Tangshan area The spatial analysis of the subsidence process in urban district of Tianjin City reflects that the land subsidence in this place may still have a increasing trend in total The spatial prediction on the basis of gray theory shows that the mean spatial subsidence in study area will increase from 16 55 mm in 1990 to 19 38～19 77 mm in 1994, and probably will further increase to 22～24 mm in 1996. |
