Analysis On The Development Law And Disaster Factors Of Geological Disasters In Songming County,Yunnan Province

The incidence of geological disasters in Songming County of Yunnan Province is higher,and landslides,mudslides,collapses and other disasters occur frequently,in order to more fully understand and strengthen the prevention and control of geological disasters in the later period.In this paper,the related theoretical disciplines such as geology,grey system science and nonlinear fractal-ism are used.Combined with the survey data of long-term field work,qualitative and preliminary quantitative analysis of the occurrence characteristics and impact factors of geological disasters in Songming County is carried out.Through research,the main contents and results of the thesis are as follows:(1)Overview and characteristics of geological disaster development in Songming County:The type of geological disasters in the county,the relationship with geological environmental conditions,and the statistical law of spatial and temporal distribution;Analysis of the causes and influencing factors of geological disasters in Songming County: Exploring the basic geological conditions and dynamic factors of county geological disasters,and briefly analyzing their causes.(2)Research on the development system of geological disasters in Songming County:According to systematic relevance,fractal dimensioning and other systematic,nonlinear theory,combined with county geological hazard survey data,qualitative analysis and induction;Under the condition that the basic data is relatively sufficient,the gray correlation analysis is used to study the largest correlation factor among the geological disaster influencing factors in Songming County,and the fractal theory is introduced to explore whether the geological disaster system of Songming County has the characteristics of fractal dimension.Provide certain technical and theoretical guidance for the subsequent implementation of geological disaster related prevention and control measures,and serve the better prevention and control of geological disasters.(3)Combining systemic and fractal theory,such as systematic and nonlinear theory,it has certain application value in the research direction of geological disasters,and provides a basis for researching the spatial scale of geological disaster development system.For example,in the county(city)regional geological disaster point densely distributed area circle painting,or to identify the intensive development of geological disasters within the province or country,you can choose different survey and analysis density according to needs.
