Abstract

Based on the features of variety and variability of geo-hazards,and using the map algebra and GIS technologies,the authors design a geo-hazard early warning model,and analyze the influence factors of geo-hazard including terrain,physiognomy,hydrology etc,and find out the relationship between the geo-hazard distribution and geo-environmental factors of Tianjin City.The warning system has been playing a considerable important action to protect life and property of human for resent years.
