On account of the special landform,geology and rainfall condition,Tianshan Mountains influences on the traffic normally.It often comes under bedload,coast,dilapidation at one time.This threatens the stability of the road and the security of denizen along the line.It is especially important to setup the geological disaster decision-making sustain system based on GIS (Geography Information System) in Tianshan Mountains to bear the advanced technology.After analyzing the on the theory of geological hazard about Tianshan road in detail,collecting the datum of basic geography and geology along the lines of road in the past and also contrasting the locale results and remote sensing images,it is built and consummated that both the geography database and the geological hazard database based the platform of ArcGIS after according synthesizing,coordinating,choosing,concluding and changing by the rules of database.Based on the ArcEngine platform,it is developed a set of collections foundations data gathering,the memory,the management,the retrieval,the graphic editor,the space model analysis,the line region stability assessment and the highway alignment route selection as well as the three dimensional route flight achievement graph production.The output is a body “the Tianshan highway geo-hazard stability appraisal and the route selection optimization analysis system”.The data and multimedia information system are integrated in the system,which realizes the function of space in formation query and analysis.It should provide the decision-making and management application platform for the territorial resources and traffic construction management department.
