摘要: With the social and economic development, losses caused by natural disasters were more serious. Natural disaster assessment, management research are important field, developing direction hotspot issues on science geo-science in resent year. However, because most of a small sample events, uncertainty disasters, so risk assessment is particularly difficult based historical data. Information diffusion theory useful method for even; it fuzzy approach to quantitative analysis probability risk. Therefore, information has unique advantages management. This chapter presents Geographical Systems (GIS) theory-based methodology spatio-temporal taking grassland fire Northern China as case study. Firstly, we discuss connotation forming mechanism risk, basic framework Secondly, introduce theories form definitions, theorems applications comprehensively systemically. Finally, give study application area China. We employed matrix analyze quantify relationship between number annual severe burned area. also evaluated consequences 1991 2006 data from 12 provinces. The results show that probabilities damage rates different levels increase gradually southwest northeast across can be predicted effectively using disasters. result shows reliability tested two-tailed Pearson correlation coefficient. contributes reference decision making prevention stockbreeding sustainable development planning. could provide make compensation plan affected
