Integrated Risk Assessment of Landslide Hazard in Fuzhou Municipality based on the GIS Technique

Lin Jinhuang;Yu Jinhui;Geographical Science College,Fujian Normal University;  
Frequently occurred,landslide hazard is one of the most serious geological disasters in Fuzhou Municipality,with the characteristics of strong destructiveness and sudden. Based on the existing landslide sites in Fuzhou,with the GIS analysis method,it was conducted the comprehensive risk assessment by considering comprehensively disaster environment,disaster causing factors and hazard bearing body. The results show that the comprehensive risk of landslide disasters is overall low in Fuzhou Municipality,which is mainly concentrated in the levels of medium risk,medium and low risk and low risk,with the corresponding area accounting for 34. 83%,36. 16% and 18. 39%,respectively. There is significant spatial heterogeneity in comprehensive risk of landslide disaster among the counties,the higher comprehensive risk of landslide disaster mainly concentrates in the downtown area such as Gulou,Cangshan,Taijiang and Jinan Districts,and the lower risk of landslide disaster mainly concentrates in the suburbs such as Minhou,Lianjiang,Mawei,Yongtai and Minqing Districts. This is mainly due to the common combination of landslide hazard and vulnerability of hazard bearing body. The internal driving of the characteristics of spatial distribution may be the higher population density in the center area and higher level of economic development,which has led to the higher population vulnerability and landslide hazard,and then to the higher comprehensive risk of landslide disaster in the region. While the urban gravity effect is lower in the suburb areas,leading to the lower comprehensive risk.
