Zhuzhou City, Geological Hazards And Their Characteristics And Hazard Zonation Study

Zhuzhou city, located in the east of Hunan province, is not only a major industrial city and the largest transportation hub in the south of China, but also is an important part of "Two Types" society which is called ChangZhuTan. In recent years, with the rapid development of national economic, the geological disasters frequently take place, do serious harm to people's lives and property, seriously hamper the sustainable development of society.On the basis of field inspection and detailed analysis of geology datum, the main types and the development features of geological disasters in Zhuzhou are summed up, then the time-space distributing rules and the formation mechanism of geological disasters are revealed. The research shows that geological disasters are given priority to small scale and soil type, and distribution and density of geological disasters have close relation with the geological background such as terrain and physiognomy, stratum and lithology, geological structure. Most geological disasters develop along with the river, and it is accordant with the rainfall on the time distributing rules.According to the local condition in Zhuzhou, improvement fuzzy comprehensive evaluation method is used to evaluation the geological disaster, and geological disaster zonation model based on many fountains communication is established with speediness distinguishing analytical method, That program is compiled with FORTRAN compiled language that can exactly and quickly finished multi-level geological disaster zonation. 5 high risk, 4 medium risk and 2 low risk area in Zhuzhou are regionalized by the program.The hazard zonation of geological disaster in Zhuzhou can be provided scientific basis for local government's work, and provided good consult to study the geological disaster in Hunan province.
