Snow damage is one of the top ten hazards facing the world , are widely distributed in the world , appears frequently human production and life , and the lives and property of harm . The snow damage research is focused on the analysis of the genetic mechanism and characteristics , its prevention and disaster prediction , not yet mature , less appropriate zoning and evaluation . GIS has a strong advantage in spatially distributed data collection , storage , extraction, conversion and operation and display a variety of modeling , spatial analysis , statistical analysis , and various forms ( graphics , images , tables, and data ) output the current the various disasters zoning evaluation in a wider application . In this paper, New the railway Jingyihuo along the railway area of Xinjiang study harm genesis mechanism and disasters features along snow GIS platform combined with the analytic hierarchy process method , respectively the regional wind and snow , avalanche and engineering typical section of wind and snow disaster evaluation , more fully reveal the characteristics of the disaster on the entire area of the along the Jingyihuo Railway . Start from the analysis of the environmental and geological factors , meteorological factors , hydrology vegetation and subgrade type factors for the lack of meteorological factors and vegetation factors analysis snowstorm relationship with various factors , and establish judgment matrix , so the other factors of the lack of data terrain factor judge instead , the judge , to make up for the lack of data . The use of mathematical statistics and expert experience to determine various factors inter-relationship , to determine each factor judge space ; GIS platform for the establishment of each of the main factors of thematic layers , using Analytic Hierarchy Process evaluation along regional and test a typical section of the snow victims divisions to determine the disaster-prone areas , prediction and prevention provide a scientific basis for the snow damage .
