摘要
On the basis of geological hazard assessment theory and land resources value theory, the land resource vulnerability assessment methods are discussed in geological hazards risk assessment. The factors affecting the vulnerability are intensity and susceptibility of land resources, which are affected by land use patterns, soil types. Therefore, a mathematical model is established for calculation of the vulnerability. Considering the economic, social and ecological values of land resources, the calculation of vulnerability and zoning of land resources vulnerability are carried out. oft-com:office:office" />
