Study On Zoning Of Geological Hazard And Manage Information System

The geological hazards during these years are very serious, which primarily lie in the province of Yunnan, Sichuan, Chongqing, Guizhou, Hunan, Hubei, Guangxi, Shannxi, Shanxi, and so on, specially in the western area of china. The prevention and cure of geological hazard has close relation with the safety of life and possession, and determine whether it will succeed in great projects.In this paper, based on the research task of"research on geologic disaster prevention and cure programming", a series of problems about the prevention and cure programming of geological hazard are analyzed and studied by use of systemic viewpoints; According to the principles of zoning of geological hazard and the actual geological condition of Yongchuan city, the layout of the prevention and cure of geological hazard in Yongchuan has been done, geological disaster manage information system of Yongchuan also be set up. The mainly contents contain:(1)Based on both the experiences of geological hazard research and the achievements of former, according as correlation criterions and by use of filtrating and optimizing method ,the happen degree division evaluation guidelines are studied; And the city prevention and cure division methods has been discussed.(2)According to the datum of traffic, weather, geology, hydrogeology, engineering geology, the circs of geological hazard, and so on, the layout practice of the prevention and cure of geological hazard in Yongchuan has been done: firstly, use for reference of both the experiences of geological hazard research and the achievements of former, the geological hazard happen degree division evaluation guidelines system in Yongchuan has been set up, secondly, guidelines weight in Yongchuan city are ascertained by use of the analytic hierarchy process software, lastly, introducing gridding dividing method , the geological hazard happen degree division in Yongchuan city are researched.(3)Based on computers and using the flat roof the soft of GIS, geological disaster manage information system based on is set up, every of functions, which contain the uniform storage , comprehensive of datum , the management and application , centralized storage of the datum of geological hazard, uniform storage, frequently query, conveniently gains, share of information, are come true.(4) According to the specific circs of Yongchuan city, the geological disaster manage information system is used in the process of prevention and cure of geological...
