Study On Geological Hazards And Its Prevention And Control Countermeasures In Mingxi County,Fujian Province

With the frequent occurrence of earthquakes and other natural disasters in China,the study and prevention and control of geological disasters has become an urgent subject to be dealt with.China is a land of frequent geological disasters and involves a wide range of hazards.Geological disaster is to point to in under the action of the forces of nature or human damage to the environment,the emergence of landslides,collapse,and debris flow,unstable slope,ground crack,ground subsidence,ground subsidence phenomenon related to geological changes,etc.Geological disasters have their natural and objective side,but there are also a lot of geological disasters are induced by human.Especially the change of geological disasters along with the development of economic and social,human engineering activities,economic has also intensified its efforts for the development and utilization of land resources,the resulting geological disasters have occurred,direct threat to people's life and property safety,affect the local economy development and social stability.Effectively preventing and controlling geological disasters has become a very important task.Taking Mingxi county geological disaster in fujian province as the research object,Mingxi county topography and geomorphology,hydrology,meteorology characteristics,basic factors such as stratum lithology,geological structure,determine the weights of evaluation factors,to determine the geological disaster formation of the natural factors and human factors;Evaluation method and GIS method and use the unit area,to partition and Mingxi county geological disaster evaluation,the present situation of the geological disasters in Mingxi county,type,distribution,characteristics and development trend of regionalization Mingxi county,prone to geological disasters can be divided into low high rock,rock,rock level 3,finalized MingXi county areas prone to geological disasters in eastern,central and southern,and further strengthening the geological disaster prevention measures and relevant solutions,to provide feasible prevention Mingxi county geological disaster in prevention and control strategy,as Mingxi county to carry out the strategy of sustainable development to provide strong technical support and environmental protection.
