### Abstract

This research raised the method in risk assessment of low temperature and cold damage, drought and flood disaster based on information diffusion theory. Taking low temperature and cold damage for example, through a comparison between the calculated results of risk index method and subjective frequency method, direct risk assessment, has obvious advantages: (1) it needs simple calculation process and less information; (2) it helps for risk assessment and zoning through different levels of risk assessment; (3) it can also used into other natural disaster risk assessment; (4) it can do the research of risk assessment in small county and town through information diffusion theory for less information.
